Ok, so I started my aquarium about 2 months ago. Everything was going somewhat great until now. I did a water test and my ammonia is just a little bit high, not too high is like .05 on the scale. And my ph is around 7.8. Today my fishes had white spots all over, and I decided to treat them for ick. The spots seemed to have disappeared. I have a type of red algae on my tank, is growing on my sand and rocks,(I had this problem for a while now, it seemed nice at first but it seems to be out if control now). I have 5 small fishes and about 20 snails/crabs. Any suggestions?
Oh so far I have made 2 water changes of 5% with water from my regular water filter. I added stress remover or something like that to remove chlorine and such. I have added water twice due to evaporation (no salt added).
