I decided I wanted to use a 20g high to setup a high tech tank a couple months ago. All my tanks have been planted, but not aquascaped or co2 injected or anything. My main issue is algae control, at first I just had bright green algae on the glass but now I'm dealing with algae on plants and rocks too. Mainly I've got dark green spot algae on my ludwigia leaves and a bit of hairish algae on my hairgrass. It's gotten to the point that I have to clean all the walls of the tank thoroughly every week or it turns into a green murky mess when I look at it.
Here's what I have going on: my light is a Finnex Planted+ 24/7 CRV (was on max for ~8hrs/day now on the 24hr cycle), Seachem ferts(I'll attach a link to my schedule), co2 running about 1 bubble/second, and a Fluval 207 Filter on about half power. I've got a couple honey gourami, 5 ottos, and 4 amano shrimp. My NH3 is 0ppm NO2- is 0ppm and NO3- sits around 10-20. I used inert substrate and I've used flourish tabs rather densely in the substrate. I use RO water and do a 25% water change each week.
I've tried to fix the problem myself, but after reducing lighting to around 4hrs/day and not ferts for a week the problem really hasn't changed. I've tried raising my co2 injection rate, but any high than 1 bubble/second and my gourami start gasping and sitting on the substrate. Perhaps it's something else but I can't figure it out. All help/advice is appreciated!
