Bpm for nano tank?

Hey guys just wanted to know wat you guys think is a good bpm rate for my 8 gallon fluval flora. Im using paintball and co2 regulator pushing through a glass nano diffuser. If I set it anything less than 120 bpm (2bps) it won't even push through the diffuser. It's running at 180 bpm(3bps) right now, fish are not bothered but co2 drop checker never changes. Stays dark green.

BPM and WPG are the same thing, a sort a guide line at best. And that's being generous.

If your fish aren't bothered by it then it's not too much. You cold probably even turn it up more.

use a drop checker and visual queues from your fish to set the co2. bubbles are different sizes so it would be a like trying to shoot a target in the dark, you might get close or you might be a long way off.

You can have various tanks the same size and the bpm will differ to achieve the same level of co2

A heavily planted shrimp tank is possible!

Hi thanks for the replies. My fish aren't bothered but my shrimps will not tolerate it. My drop checker never changes colors unless I flood the tank with co2. My goal is to keep shrimp and fish and plants all happy in one tank. So far I'm 2 out of 3

Try moving the drop check around a bit, might simply be a case of the co2 not reaching where it is atm.

Got a tank? Doing it filterless? Add it here!
