My boyfriend and I started using Seachem Flourish Advance a few week ago and our plants are doing great but green furry looking algae starting growing so quickly on everything. Our poor little lone nerite snail is useless to all the algae that instantly started growing. We stopped putting that in this week because its out of control. We just got a new filter last week and the new media that's in there is also all covered in furry algae. We leave our light on for 6-8 hours a day. What can we do? I added some pics so you can see what I mean, its been maybe 3 weeks.
