| || | Pressurized co2 in heavily stocked tank?
I'm going to order my pressurized co2 this weekend, and I have just a few questions please...
I've been reading everything I can to try and get ready to get it going when it gets here, and I came across an article about CO2 not being safe for the fish if it is a heavily stocked tank. Is that true? Also it said something about if it is a covered aquarium (glass tops) the co2 will form a layer in between the water surface and the glass and prevent oxygen from entering the water. I have to keep mine covered because of cats. lol Opinions?
Also, what is a good ppm of co2 to start at? Should I start low and work up or something?
Stocking (75 gallon):
4 dwarf neon rainbows
1 red tailed shark
2 botia striata
1 common pleco
