I have a new 55 gallon freshwater aquarium that I set up almost 2 months ago. I transfered one filter from my old tank along with some rocks and one plastic plant to speed up the cycling process. That seems to have worked. I have had some low ammonia levels, but never any nitrites, and have had nitrates after the first week. I'm concerned because there is absolutely no algae growth at all. The plant that I transferred from the old tank had quite a bit of algae on it and it is slowly dying. I've never had this happen before. My water is soft and the ph stays at 6.0. Alkalinity is low and there is still some ammonia which also concerns me after two months. I expected the cycling to be complete by now. I have not added any new fish. I have an 8" pleco, which I'm having to feed algae wafers, and a 5" blood parrot (did not buy it, someone gave it to me). The fish seem fine. Any opinions on this?
