I have a 67 gallon tank, running a Fluval 306 and a Fluval 305 canister filter. My tank has been running for about 3 months and I thought it was cycled. Although I added fish over a period of time, I must have done it too quickly and "set back" or "stalled" the cycle. I am not convinced it has cycled yet as every 4 or 5 days the ammonia shows a little high. I use the API testing kit. Although comparing test colors is a little tuff sometimes, the ammonia has always been between 0 and .25. Nitrites are always 0 and nitrates at 5. Ph was always about 7.2 or 7.4 but have been slowly climbing and are now at 8 or 8.2. I was doing 20 to 25% wc every day to control ammonia but now have backed off to about every 3 days. I have a Fluval E300 heater (which I am not impressed with) and try to keep the temp at 26 degrees. I say try because the heater will not keep it steady, but it only varies by .5 to 1 degree, and that is as high as it will put the temperature. I have 1 red tail shark, 4 bronze cory's, 7 Tiger Barbs, and 8 assorted Platies. (had 10). I have a small floating plant (not sure what kind it is), and recently added 2 small bunches of hornwort Before adding hornwort to tank I rinsed it, washed it in a mild bleach mixture, rinsed it, put it in dechlorinated water for a few hours, changed the water and let it sit overnight.
3 days ago I noticed 2 Red Mickey Mouse Platies (one male and one female) had a white spot/bump. Both were on their left side, lower than the fin, but near the top of the fish. They were acting "lazy" and would not eat--hiding in the hornwort or at the bottom, by themselves. I asked this question on another forum and have not received a reply yet, but both fish have died. As sad as that is, I am wondering if it will effect the other fish--and what do I do? The others are acting perfectly fine. I added pictures on the other forum but have not found a place to do it here?
Sorry this is so long but I thought it might help if people have somewhat of a history of my knowledge and the tank. I will appreciate any advice. Thank you.
