Hey everyone I'm questioning if I should run a DIY co2 or not. Ok so right now there is a moss ball, baby tears, dwarf grass, and java moss. My ph is 7.2. I have 5 black skirt tetras, 5 adult guppies and a bunch of baby's, 3 neon tetras I may get 3 more bc one sits in the corner I think he wants more to school with, a gold nugget pleco (l177), and a candy stripe pleco. I have a 4x36 t5 lighting system, 3 6400 bulbs was 4 but one blew out. I'm gonna put a 10k if it is suitable but idk that either. I'm new to the planted tank part. I am getting growth but not fast enough. I'm afraid if I add more plants I'll limit growth. Any suggestions on anything here will be greatly appreciated. I'm on a very limited budget. The 10k light would be from a former reef tank.
