Well, its not a tank cycle cause the tank is years old... I don't think its water movement as I have 2 filters and a bubble wall and there is generally a lot of current except when the filters start to clog.
I always thought light caused algae? Everyone always says don't put your tanks in direct sunlight cause that will cause algae... so why now is poor lighting an issue?
I am probably gonna go with the hard water thing. I live in the city and its not well water but I know from when I used to check that, my water was always hard and the PH was always low. I had to solve that problem by adding crushed coral to all my filters.
Oh well... guess I just have to deal with it.
