Tom Barr No-CO2 Method, still new at this, just mucking everything up.

So some history. 20 Gallon long, set it up late May, cycled by early/mid June. Have had it stocked with 1 betta, 5 julli cory, 1 snail, 3 otocinclus, and a varying amount of neon tetra (as low as 6, currently 17).

I've been basically OCD about following the rules laid down in r/Aquariums. 25% WC every week since fish first hit the tank after cycling. Gravel vacuuming. Making sure not to overfeed, had an Ich outbreak thanks to the tetras so I dealt with that for nearly 3 weeks. Lots of water changes.

So I'm sure you can see where this is headed. Basically, my plants were fine for the first 2-3 months. Amazon swords experienced some melt (as usual) but came back strong, Bacopa was the best grower in the beginning, and the anubias were doing well. Since my motto was "Keep the water clean", I never saw nitrates after the tank was done cycling. 0/0/0 for a LONG time. When I was finally done treating for Ich, I noticed that the plants weren't looking as good as usual, and I had the beginnings of an algae problem.

After a whole bunch of conflicting research and opinions both here and on various forums, I decided that my best bet would be to buy the E.I. fertilizer kit from GLA and start with Tom Barr's Non-CO2 method. Basically, I dose 1/8 tsp NO3, 1/32 tsp KH2PO4, and 1/32 tsp trace nutrients. I do this once per week and will only be topping off the water. Maybe a gravel vac here and there.

The plants have all started to grow new life and seem to be doing much better, but the algae issue is persistent. Some of the anubias and almost all of the old growth on the bacopa is covered in thick, hair like green algae. Like ultra-dense, short grass.

Should I go grab some Excel or some other algaecide? Should I clip all of the bacopa at the substrate and start over with them? Clips the anubias?
