I’ll follow up with those details tomorrow. Thanks for the insightful reply!

So we let it go. Original fish are fine, it’s been a year. Algae growth was insane. It was a planted tank. Sand for substrate. Big lava rocks were the only objects. It has a fluval 307 and I don’t recall what media I used in it. So I got fed up and I’m doing this again. So I pulled out all features, cleaned walls and heaters and tubes. Flushed a ton of water and siphoned the sand (leaving it in). Only one plant survived my fury. And fish of course are still fine. Hopefully they’ll handle the drastic change. We have hearty tetras. Anyway on this rebuild I really just want to eliminate all algae. This keeps happening, it shows up quickly and aggressively. Few Qs: Is my expensive fluval light too strong? Should I gut the 307 and fill with new media, if so what do you suggest? I’ve kept track of my water conditions with the fluval drops and such but I’m not understanding what indicates such a prime environment for algae. It’s bad stuff. Really ruins the tank aesthetic and makes it not worth keeping a tank. This time I think we’re going the fake route with classic fish tank ornaments and keep it simple.
