  1. Once a tank is cycled, I've never really seen a problem with ammonia spikes, unless the water quality is really bad... I've sometimes seen unexpected nitrite spikes in tanks that I thought were cycled, but really didn't build up enough BB that consumes nitrites. What are your nitrate and nitrite readings with that level of ammonia?
  2. Yeah I hate it when I think I got an amazon sword planted just right and not too deep, and it floats to the surface about 5 times. Then I jamb it in, and I know its too deep, lol.
  3. I have that in my 53 gallon display tank setup in August (no C02, crypts, java fern, val, etc). Finally starting to look really good after 4 months, plants finally overtook algae and are growing nicely. Water is very clear. And I barely fertilize.
  4. I saw the video with Jason from Prime Time Aquatics talking about the Ziss. He had a light shining right on it, as I do with my SF bay hatchery. I place a flexible arm desk lamp with a 40 watt bulb right over the open top of the 2 liter bottle. So I get light and heat. It keeps the water exactly around 80 - 81 degrees, with my room temp around 70 degress.
  5. I actually felt the same way and was thinking about blue when I was looking to get a pair. Right before going to pick up a few, I saw a YouTube video with Dean sitting in front of a 29 gallon tank with 13 beautiful koi ... so I ended up with a pair of koi 🙂 Good thing though, because 4 local shops said they sell well and would be willing to buy them. I have a question, which I why I looked for this thread... I have a black marble and a koi that paired unintentionally. After pulling the eggs I finally have a batch that was not eaten. Just starting to vaguely look like "darts" ... what would you expect them to look like from a black marble and koi? Real hard to tell at this point, but almost looks to me like I see some light, orange, and a good amount of black almost like the koi with a lot of black.
  6. I have diatoms on my two newest tanks, I know they don't bother anything but I'd rather not look at them, at least on the glass, and on the plants... It's been over 3 months, and I'm starting to finally see plant growth picking up, so I'm hoping that reduces them. I'd post a pic, but I just cleaned most before last water change. Always starts to form within a week.
  7. I've been making these every day for a while, following the instructions in the great video by @Irene. I made a couple of minor adjustments: 1. I don't know if this is true, but an experienced breeder said he finds it better if the salt melts before starting, so I put the salt in a cup and add a small bit of really hot water to melt it before adding it. 2. The SF bay site, who also sells the eggs, gave the range of salt needed for hatching, and they claim that the eggs hatch better at the lower end of the range, so I use exactly 1 tablespoon, instead of 1 2/3 - 2. I am pretty sure I noticed a difference, but would have to repeat to confirm. 3. I add half the water, then the eggs. I leave it like this while I clean up, then add the rest of the water and cover with the light. Lets them get water logged without me needing to stick my fingers in and push them back down 🙂. The 40 watt bulb right over the top keeps the temperature right at 80 degrees. 4. When draining the BBS, I point the light at the very bottom, and put a towel over the top of the bottle to block out all light except the very bottom. I did this after seeing Dean shine the light at the very bottom in a dark room. I think it helps. Leave it about 5 minutes, then drain until it runs clear. Leaving it covered and light still positioned, you can let more collect at the bottom and drain again after a minute or so.
  8. I actually found this thread googling. I'm going through the same thing right now. I actually have 3 batches going. One from a nice pair of Koi and two from a pair of Petco angels (koi and black marble) that kept spawning in my community tank. The koi did a great job raising the first batch, but ate the eggs the second time, and the female was not eating well so I pulled the second batch of eggs so as not to stress here. A huge thanks to @Brian Scottfor advising me on exactly what to do to get her eating again (which was different from advise from two other experts)! Anyway, I know some experienced breeders say it's easier (and better yield) to hatch the eggs separately, but I found much easier to let the parents do it, if they can. I swear, it seemed like they even knew how to eat and swim better the first few times when with parents, like going right after the BBS rather than watching it drift by and taking days to learn to eat. I see why @Brian Scott prefers this method! Anyway, I'm currently using two large glass jars with airstones submerged in a 10 gallon tank that has a heater in it. I take the jars out and place them on my desk in good light for feeding and water changes. Will move them into 10 gallon tanks with seasoned sponge filters soon by draining most of the water and pouring them into their rearing tanks. The first batch that were raised by the koi parents came out extremely well. Any that were lost were too small to notice, and I only found 1 dead body since they reached the "dart" stage. Only one or two obvious deformities out of about 190 - 200, but I have to examine them closely.
  9. I need that! We must be around the same age, lol
  10. I just got this yesterday! Like $19, a 2.5 gallon serving thing from target. Angel spawn on breeding cone, wanted something to put it in with a mini heater and airstone, but easily able to change water when needed and this drains, so I can pour water in while draining and keep the eggs under water.
  11. Use wood shims. If it's crazy out of level, you may need something else like 1x6 or whatever, with wood shims on top to make small adjustments (I think they're like 1/4" or 1/3" max) but I've never had a floor that unlevel. I use the black composite wood shims from home depot or lowes, they are strong and you can break them off easily.
  12. Yeah, the DIY guy on YouTube builds all his own stands, and had a tank explode sometime later, because a pebble came off his shoe when he was climbing on the stand, and it was making contact with the glass. Also make sure stands are level, regardless of rimmed or rimmless ... probably a non-issue for 5 gallon tanks, but could be for larger tanks.
  13. I know it would be better to use in food, but if a fish isn't reliably eating has anyone used Metroplex in the tank water as described, and successfully treated parasites like hexamita, as in a definite improvement after treatment?
