Ok, I just tested the water>
Ammonia: 0 ppm
Nitrite: 0 ppm
pH: 7.4 to 7.8
I don't have a way to test nitrates, but with everything reading normal, nitrates should be low to none. When I did the water change I noticed, besides an ugly site, I had sturred up tons and tons of either planaria or nebatodes (they are like 2 mm in length and white). I don't know if this could be the cause, but I know for sure that they won't be eating for a while. Since it is only the 2 fm's with a common pleco, I thought I was giving them a small amount once a day. Any other useful info would be nice!!! Thanks!
BTW, I have noticed round the edge of the aquarium, fine concentrations of air bubbles. Almost looks like a foam of some sort. I don't know if the possible foam is trying to tell me something or what. I really need some answers and help!!!
