Guys here's a helpful POV, my tank is a 220 and I have higher than normal algae growth and I have a few acros that are doing well but I also have a thriving colony of FF Digi I bought from Dong a while back. It's been in both high and low flow areas of my tank due to me being unable where to keep it and it seems to enjoy both oddly enough. Maybe your water could be too clean? I'm one of those weirdoes though. Also I do plan on reducing the levels of elements that are causing the algae growth so that'll be interesting to see how it does. My lighting is 3 250watt radium's on for 8ish hours a day, also its a bare bottom, with skimmer and sometimes a filter sock and carbon bags.
