I've been playing with lighting times. Currently running about 9 hours a day. I will try the Nerite snails.how long are you running your lights each day? Do you have a lot of plants to compete with algae for nutrients. How often do you do water changes? Toss some nerites in there to eat algae, they are good at it.
It very well could be. The tank has been running for about 6 -8 months now.From what I understand, isn't this part of the after-cycle?
I've tried everything when it came to ferts. Researching algae's some suggestions will state, add this fert, reduce that one, ect... Eventually I just stopped using ferts all together.If I also recall, stopping and starting ferts is part of the problem.
