About Me

  1. So I am unsure/curious about this. My grandma set up a new tank about three months ago for her angelfish and recently began trying to add more. They all came from the same pet store and of the four total she bought only one survived. Of the first two, one had notable deformities and died within a few days because it couldn't swim properly and kept ramming into the tank walls. While the last two she purchased a few days ago, along with two silver dollars for the same tank and a goldfish for her goldfish tank. The silver dollars and the goldfish are doing perfectly well, but the two angelfish died the next day. She tried to get a refund for the angelfish and the pet store had her bring in some tank water to be tested. According to them, there's 0ppm of ammonia, nitrite, and nitrate in her tank. The employee said the fish died because her tank is too clean and that there's no nitrogen cycle going on. The tank water does get cloudy very quickly, but I'm pretty sure that's because my grandma has a tendency to overfeed. That being said, I'm pretty new to the hobby so I don't know much about the nitrogen cycle beyond the basics. My grandma is very discouraged and might stop keeping angelfish. The thing is, she's been successful in keeping angelfish in the past. I've never heard of tank water being too clean and want to know if that was the pet store talking bs or if there is a potential legitimate issue that could harm the (seemingly healthy) fish still in the tank. It would be terrible if more fish died, she's already extremely stressed from other non fish related things and took these deaths pretty hard.
  2. I've been using the Coop's Ammonia test strips and I've noticed that they get bluer (indicating more ammonia) after they've come out of the water and sat for 10-20 seconds. I'm wondering when I'm supposed to read them. Is it immediately after it comes out of the water, or should I wait?
  3. What is an acceptable range of ammonia? My tank is currently at 0.25 ppm. Should I do a water change? All other perimeters are perfect.
  4. I started cycling my tank 11 days ago. It’s fishless but I did add ammonia (started at 2ppm) and api quick start. Tank is 37g. Ph is 7.6. Yesterday I went to a fish store and purchased a fish but won’t be getting him until this is cycled. While I was there the guy gave me about half a gallon of water from one of his tanks that he squeezed out his sponge filter into and it was super dirty so I assume it grabbed a bunch of stuff to help. I poured it into my tank. How long do you think I should be seeing changes for the cycle? I did it last night and my ammonia now looks like it’s at 1ppm but idk if it’s like that because I added some water or not but nitrites is 0. I did nitrates for the heck of it and I think it’s a little orange? It’s strange the tube looks orange but when I pick it up and look through it in the sunlight it’s yellow but a tad more yellowy orange than the 0 level yellow if that makes sense lol (using api test kit)
  5. I started working at a local fish store recently (yay!) and I’m finding myself struggling with explaining the nitrogen cycle to newbies. I feel like I tend to over explain things and intimidate/confuse people, so I’m trying to come up with a simple-ish explanation and diagram to guide the conversation. This is a very rough draft, and I need input before I finalize the design and actually make it look artsy and nice. I am usually a good salesperson, but I feel like I’m already failing at this job because people’s eyes glaze over when I begin to talk about the components of aquarium ecosystems and water quality and whatnot. Is this normal? I feel like this is vital information for the wellbeing of an animal and I find it really unnerving that people seem to not care. Any advice about this would be welcome, my confidence in my position has taken a bit of a hit because of the interactions I’ve had recently. Copy/paste of text portion for easy editing: Beneficial “nitrifying” bacteria grows on all surfaces in your aquarium where water flows, including decorations, substrate, plants, and most importantly: filter media. Porous media such as sponge and ceramic make excellent homes for these beneficial bacteria, which convert toxic ammonia and nitrite to much less toxic nitrate. These bacteria colonies take time to grow in a new tank, from 3 to 8 weeks, and this initial bacteria development is known as “cycling a tank.” High nitrate levels can still harm fish, which is why water changes and/or live plants are essential to keeping a healthy tank. Testing your water regularly to keep track of ammonia, nitrite, and nitrate levels can help you understand your tank’s ecosystem so you can keep your fish healthy and happy! Always wash dirty filter media in used tank water. Chlorine from tap water can kill your beneficial bacteria and may cause your tank to “crash.” A crash happens when there isn’t enough bacteria present to convert ammonia and nitrite, so the concentration of these toxic compounds rises to harmful levels. (Side note I just realized I need to write out “carbon dioxide” next to CO2 for consistency, I’m sure that’s not the only mistake I’ve made)
  6. Hi all! I am replacing my HOB with Large sponge filters on my 75. How long do I wait before I can take off my HOB. I have 2 Sponge filter in the tank for one week now. And 2 HOB's. One HOB has crushed coral, so Ill be keeping that and maybe just have one Sponge filter. Thanks for any advice!
  7. on aquarium coops new video about nitrogen cycle he says he doesn't test for ammonia all he does is add plants and wait for growth. Once you see growth does that mean the cycle is done?
  8. Thinking it's finally cycled. Ammonia 0 ppm Nitrite 0 ppm Nitrate 80 ppm I would assume that a water change is in order. This is a 29 gallon tank. What next? If a water change is in order what percentage?
  9. I'm into week two of cycling a 29 gal. I'm using a sponge filter and a ziss bio filter. Can anyone tell me where I'm at with the cycle?
  10. Here's what currently in my dad's 30 gal aquarium. Water is a bit yellow due to the tannins from the driftwood. Thought I soaked it long enough to remove the majority of it but I was wrong. hehe Plants 6 Vallisneria gigantea 1 Taiwan Aquarium Moss Taxiphyllum Alternans 2 Brazilian Pennywort Hydrocotyle Leucocephala 3 Pearl Weed 1 Willow Moss Fish 2 Cherry Shrimp 4 Variatus Hifin Blue 2 Green Lantern Platy 1 Glo fish. 2 Dalmatian Mollies 2 Clown Pleco 10 Amano Shrimps 2 Hill Stream Loaches Want to add 3 Khuli Loaches to the mix and maybe 2 Bristle Nose Plecos.
  11. We are 4 months into a fish-in cycle for our 1 betta in a 5 gallon aquarium. I posted awhile ago about a sudden pH drop and we have gotten that issue taken care of. However, we have not ever registered nitrites or nitrates. We use Prime daily for the ammonia, which has never risen above .25. We have added API Quick Start and Brightwell MicroBacterStart XLF. Our Betta's fin rot is progressing so we are getting desperate trying to figure out what to do. Any advice is appreciated.
  12. I am currently cycling a 16 Gallon aquarium. As of now, it has two inches of ADA Aquasoil Amazonia, 2 inches of pool filter sand, a large driftwood piece, one bahai stone, a seeded sponge (has been used continuously for 2 years), and Fritzyme 7. I started all of this on Saturday and so far, I am reading no Ammonia and no nitrites. How soon should I expect to see Ammonia show up? It has been 3 days and all I am registering is Nitrates (which may be from the Fritzyme 7)
  13. Set up a Fluval Flex 9 on Jan 6th. I added a bottle of Tetra SafeStart Plus that afternoon. Tap water with API conditioner. Substrate is SeaChem Flourite Black. That evening, I added plants, 2 cherry shrimp, 5 Celestial Pearl Danio, and a dwarf gourami. Testing with API Master Freshwater kit. After 1 week, I was still not showing any signs of nitrites or nitrates. Ammonia was .5-1PPM. So I added API Quick Start to help and also a handful of gravel from a friend's tank. Started adding SeaChem Stability around week 3 and been adding it daily since. There's like 7 or so root tabs in the substrate. Also weekly squirt of Easy Green. Well today is week 6 and still same parameters. Doing weekly water changes. Typically about 20-25% except for about the 3rd week which was 30% or so. I test the water after doing the changes. Ammonia .5-1 PPM Nitrites and nitrates 0 First day, Jan 6th. Week 1 Week 3 1/27. I did about a 30% water change. 1/28 Lost both cherry shrimp 1/29 Lost 2 CPD. Dont know if they died in the water or died when they got stuck on the intake vents. One was on the bottom vent. Other on top. Started adding SeaChem Stability Week 4 Week 5 Week 6
  14. I'm still cycling my 20G H aquarium since 3 week ago. I'm in my 4th week. I used fritz zyme 7 beneficial bacteria, and put fish flake to help start the cycle and I haven't gotten no reading of ammonia, nitrite, or nitrate. so what am I doing wrong? the tank is starting to get cover of white sluff I don't know what that is. should I do a partial or what to do about no readings. any suggestions.
  15. I’ve never understood what nitrates and nitrites are I’ve just known what is good or bad so what are they and(because it’s always nice to know what others think) what is a good level of both I know nitrites should be 0 but what is good for nitrates
  16. I'm going to be setting up a new tank for Cichlids, which I've never had. Can I take the filter material out my HOB from my regular community tank and put it in the new HOB of the new tank for the good bacteria? I know the PH levels are different for Cichlids, but I just wanted to make sure I am transferring the correct beneficial bacteria.
  17. I think I have had this second and smaller tank running for four weeks now. I have many snails in this tank. I think I have only seen two empty shells. I have lots (and I mean lots) bladder snails (mostly babies but plenty of adults), I think one ramshorn, and three nerites. How is it possible to have absolutely no trace of ammonia in my water? There doesn't appear to be any nitrites either. There is plenty of algae to go around and I have sprinkled a little food in the tank here and there. I have plants in there too. What gives?
  18. Hi I didn’t fully cycle my 125L tank it’s planted I only left it 7 days . How often should I check water pramiters it’s stocked with 24 juveniles
  19. Hi, I have a 29 gallon tank that I am going to be cycling soon. I did a bunch of research on Fritzzyme 7 and turbo start but no store around me carries it and a lot of reviews I read said the BB was dead because it wasn’t shipped/packaged/ stored properly. So today I went to my LFS and asked the worker if I could possibly get some filter media from one of her established healthy tanks to speed up the cycling process. She told me I could but even with the cycled media it would still take 6-8 weeks to fully cycle. Is this true because it completely contradicts all my research if it is. Also, after adding the cycled media in my uncycled tank do I need to add ammonia to the tank so the BB doesn’t die? And if so what form of ammonia should I use? I’m wanting to do a fishless cycle. Thank you!
  20. So the motor unit on my AquaClear died. I don’t have a back up filter (I know shame on me) to use while the Co-Op order with a sponge filter comes in (To replace the motor was $20-30 plus shipping, while the sponge filter was $7.....you can do the math) Will my tank/fish be okay for the couple days without a filter? What should I do to tide it over until my order arrives? It’s a 20g long with 15 neon tetras, 6 ember tetras, and a school of panda corys. Fully cycled and partially planted.
  21. I performed a large water change last night (I needed to move the tank so I emptied like 70% of it) and I am checking this following morning. This tank is covered in bladder snails and their thousands of eggs and is hopefully ready for a couple of puffers.
  22. Are there best ways to cycle a larger tank using a tank half as small? I read that I can use my new filter side by side with my old one to start seeding. I can take a rock from my tank and transfer it to the new tank. Maybe put in some of my sand from the 29 into the 60. The goal is to cycle my tank as fast as possible so I can purchase my rope fish before they go out of stock again. I would appreciate any advice!
  23. What a tank is cycling will nitrite levels go up? tested my tank today and levels were at .50ppm nitrate is at 5.0ppm is the tank cycling and should I change water...
  24. I have been using Imagitarium Biological Booster in my tank from the beginning and now my tank has finally cycled. Do I need to keep using it after each water change or is it just wasted money now that my tank is cycled? My tank is not a planted tank. TIA 🐟😃🐠
  25. Hey guys! So I’ve had my 20 gal long tank since Feb. 7 of this year and everything was cycling well with some semi-established media. Then on March 1 I found a decaying cockroach in one of my tank decorations. Since removing the roach and decoration I have done two massive water changes and subsequent ones as needed to lower the off the charts ammonia. However, even when I get it down to 0 ppm it climbs back up on its own. Before all of this I already had some Nitrites and Nitrates and then the cycle stalled. Two days ago my Nitrites finally converted into Nitrates but the ammonia is not budging. Thank you for any help. If you need more info from me let me know.
