  1. Today, I had to titrate my tap water with RO water to get to recommended harnesses... and then I went down the rabbit hole. Now I'm confused. I'm looking at my easy green and am confused how mathematically I convert the bottle contents into an ending ppm when added to a barren aquarium. Assume I am adding 1ml into 10 gallons of water for simple math. Using Nitrogen as example, easy green has 2.66% water soluble nitrogen. So for the fertilizer itself, converting from percent to ppm we would have 2.66*1000000/100=26600ppm Then putting 1ml of this into 10 gallons (37854ml). 26600*1/37854=0.7ppm (edit for 10 gallon) So even if this all went to nitrates it would only raise it by 0.7 ppm. I feel like when starting my tank (8 gallons-->0.88ppm) two pumps of easy green got me from like 5ppm to 20ppm when I was testing. What am I conceptually missing? Thank you, Brad
  2. Maybe I failed math as a kid, but I'm a little confused LOL.
  3. Hi folks, I’m doing a bit of learning about fertilizer methods, and want to get a better handle on what I’m currently doing. I’m dosing Easygreen into my oto breeder tank, and I want to figure out exactly how much. Apologies in advance for mixed units, and I'm not even pretending to remember significant digits from school. In a nutshell, I want to know how many pumps of Easygreen it would take to achieve a nitrate level of 20ppm in a 30 gallon tank. Low end of recommended dose, and a means of calibrating my brain. 20ppm means that out of every theoretical 1,000,000 parts in a volume, 20 of those parts would be nitrate. So if 30 gallons of water weighs 113562.3g as mass (1 US gallon of water = 3,785.41 grams ), I want 2.271246g of that to be nitrate (113562.3*20/1,000,000). The label says Easygreen is 2.66% nitrogen. That's not nitrate, so we need to do an extra calc. The atomic mass of nitrogen and oxygen are 14.01 and 16 respectively, so nitrate is 22.59% nitrogen by mass (14.01/(14.01+3*16)*100). Getting back to our 2.271246g of theoretical nitrate above, that means we need to add 0.51307g of nitrogen specifically (2.271246*0.2259). So in a nutshell, how many pumps of Easygreen add 0.51307g of nitrogen? 2.66% by weight would be 0.0266 g/mL assuming Easygreen is roughly the same weight as water (1g/ml). So if 1 pump is 1 mL, and 1 mL contains 0.0266g of nitrogen, does that make 0.51307g total nitrogen/0.0266g nitrogen per pump or 19.3 pumps in 30 gallons make 20ppm from scratch? That seems high, so I think my math is wrong somewhere, but I can't see where. The rotalabutterfly calc site says 3.7g of KNO3 in 30 gals yields 20ppm, as a check. The molecular weight of KNO3 is about 101 vs 62 for nitrate, which checks well against my value since 3.7*62\101 is 2.27, which I calculated above. I’m just not sure on the pumps of liquid fert. Thanks in advance for anyone’s time!
  4. I recently had to add some aquarium salt to my tank to weed out bacteria that was making some of my fish sick, I was wondering how many water changes would it take to make the water safe for planting? I just received two Java Ferns I had ordered from the co-op prior to having to use the salt and I heard that salt will kill live plants so I figured it would be best to ask before I go planting them lol.
  5. I thought this might be fun to see what people's stats look like. Active tanks only (something, plant, animal, invert, living in it). 226 / 25.4 / 9 Enough tanks that normal people think it's crazy, but few enough that aquarium people know I'm a newbie.
  6. One of the many questions @Cory gets is: How many... So, in today's inaugural episode of 'Care Forum Investigates', where average fish keepers of average intelligence attempt to solve simple problems, the question is… How many gallons of water can I put in a 10 gallon tank? I'm not the only one apparently. According to Google people have asked: Not having the fancy scientific equipment to answer the question 'How many gallons does a 10 gallon tank hold per hour?', in this episode we will confine ourselves to the 'how many gallons can I put' question. Equipment used: Non Affiliate Links Aqueon "10 gallon" aquarium: https://www.amazon.com/Aqueon-Aquarium-Fish-Tank-Size/dp/B01MRCNVSY/ref=asc_df_B01MRCNVSY/?tag=hyprod-20&linkCode=df0&hvadid=167116240456&hvpos=&hvnetw=g&hvrand=8960182847743316893&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9010107&hvtargid=pla-338193400514&psc=1 United Scientific Large Beaker: https://www.amazon.com/United-Scientific-BG1000-10000-Borosilicate-Capacity/dp/B007QO3RDA Medelco Small Beaker: https://www.fishersci.com/shop/products/pyrex-griffin-beakers-15/02540M The result after adding 37.85 liters of RO/DI tap water 25°C (but with no dechlorinator) is seen below: The aquarium began to leak at about 9.95 gallons apparently because of the lack of an unbroken seal along the top most part of the rim. Discussion: While technically possible to put 10 gallons of water in a 10 gallon aquarium, you may not be able to do so without a substantial leak. It is also possible that if we were to increase the total dissolved solids (TDS) by foregoing reverse osmosis water, that all the little solids in the water would plug the leak along the rim, thus allowing for the full 10 gallons of water. Next week on 'Care Forum Investigates': How many gallons of water can I put in a 20 gallon aquarium?
