I already have 2 weeks with my new planted tank and I think I already have algae problems. I was using a DIY co2 but I have like 4 days without using it because I got out of citric acid and I'm waiting for some I ordered. I'm using exel . Below is a pic of the tank, also the one on the back ,don't know how is that called it seems the leaf are turning brown. The light is a finnex 24/7
