Is the hex cycled? If it is, then she has an adequate colony for this purpose. It's not going to colonize more than enough to support the fish that are in the hex regardless of how much floss and noodles you stick in it. Seriously.Persimmon said:The problem here is that it not a well colonized wheel and she has no other bio in the filter system. She has only been over using the charcoal inserts. If the wheel was highly colonized or she had other media, yes, I think it would work for the bigger tank too, but from what I saw, there is no good bacteria goo build up on that wheel.
Jeeny, the wheel looks clean, have you been washing it and if so, how?
It's not over-oxygenated. It's nitrogen from the tap water. When you dump water in a tank the fish can absorb the nitrogen bubbles and get a condition similar to the "bends" that divers get.lilchris_28 said:The tank he is in now currently has a biowheel and a one of those filter pouches with carbon in it. I didn't even know water could get over-oxygenated. How do I know if it is or not? I just bought a 20 gallon to put him in in a few days after it cycles for a bit. This one just has a filter without a biowheel. I'm planning on buying another filter with one ASAP though next week I'm buying a bigger tank for my bichir. Can he just use the regular filter in his tank or does he need a bio wheel too?- I'm talking about my bichir on that one.
Wow, good catch. I missed those.rrkss said:I did not read every item listed here but looking at those images, the red veins in the tail stand out to me. Can you please give me a test of your water. Usually dialated vessels in the fish's tail signal ammonia poisoning and the blisters could just be damage done by the ammonia if this is the case.
