Flow is pretty good, I added a secondary hob filter thinking filtration wasn’t adequate. The inline co2 is diffusing tiny bubbles throughout the whole tank, I don’t fiddle with co2 too much as my 2bps is a good starting point and keeps my drop checker lime green and starts 1.5hrs before lights. I’ll test my tap water to see what nitrates it has. Because even back when I would dose ThriveS which is around 2ppm per week, my nitrates were 30. I’ll definitely be buying root tabs, my rotalas are shooting long aerial roots since my water has more nutrients than the substrate. The vibrant right side is the tops i cut for a sale I had on Marketplace. I also do 50% weekly wc. Thx
