this is interesting, you saying its more likely to happen with low-tech tanks? I have always done water changes with lights on. I never really thought about this? But I have never experienced this problem in 2 years. is there something Im doing that counteracts this?
Every tank is different, and it's more likely to happen in low tech tanks when water changes are increased.
@ Deano, if you're experiencing algae problems, you don't want to be increasing your photoperiod. Changing water after lights out is fine. Just out of interest have you added and shrimp or ottos yet?
