What a long road of difficulty Andy. I am rooting for you to get this puzzle worked out. Just so you know.
Thanks. While most people have water issues, it's not all that common, I believe, to have AIR problems with fish. At this point, I'm not even sure that ventilating the place is even the answer anymore considering that this is happening still with the place being aired out all day. But if I can get the fry to free swim at the house then move them to the building, I'd be okay with that. That's how the outside farmers do it anyway. The fish aren't spawned in the ponds directly in most cases. You just have to adapt.What a long road of difficulty Andy. I am rooting for you to get this puzzle worked out. Just so you know.
What about the possibility of air purifiers? You know, the ones for mold and smoke style of thing?
It's great to see some answers developing and some new fry coming along any which way!
Yes, I've been cheering for the fry but figured they were in good hands. So complex though!
Today is moving day. My 2 swimming spawns from next door are in the process of being acclimated to their now homes in the building. With a sponge filter, now all I need to do is more frequent water changes to keep the nitrates from getting too high.
Bingo! problem solved. Why not just put them inside a cycled sponge filter when they hatch instead of moving them? As you say a cycled sponge will take care of the ammonia problem.
If it were only that easy. I tried that and the problem was the ammonia level in the air here was enough that the nitrATE level was high in the fry water after only 48-72 hours and the fry still didn't swim. I'd have to be doing massive water changes daily and I just don't have that kind of time with so many pairs going. Even with a sponge filter, more ammonia going in means more nitrate coming out. Outside of the building, there is no ammonia or nitrates to deal with which is better for the fry. These 2 spawns are proof. But another example of why it's better for them to be out of the building, the fry from one of the tanks that remained in the building for 2 days after hatching ( and having air circulating in the building all day) are now showing signs of distress after only being exposed to the higher ammonia for just under 48 hours. ( ammonia was just higher than .25ppm.) I did a 100% water change on them and moved them next door but even that didn't solve the problem apparently. Those fry should have been swimming 2 days ago but they are just dying on the bottom of the tank. I've been using the same old proven pair as my "standard" and their first successful spawn since July of 15 is one of the ones I moved back yesterday. So I can rule out the fish, the food, the well's water and the routine because when given the right conditions, the fry survive after all those that didn't.
That's just the short answer.
Sorry to report that I lost the new babies to a heater malfunction. I was very disappointed but I will keep an eye out for a new spawn in the future.
