Co2 levels suffocating fish?

[Prediscus23]

My discus and one of my german blues were hovering at the surface of the tank gasping for air.... is this a sign of my Co2 being too high? This only happens when I turn off my power head because it blows my frogbit around. Any Ideas on what I should set my bubbles per second at?

Also does anyone know a way I can keep my frogbit from getting thrown about?
an anchor of sort?

Whats your tank size, bps, diffusion method, etc?

Also, you should really have a drop checker for this exact reason.

I have a 26 gal w/ pressurized co2 system, I have a regular glass diffuser. What is a drop checker?

A drop checker is a glass bell-shaped device that gives you a measure of co2 levels based on the color of the liquid it contains. You can pick it up for super cheap online.

What was your bps?

it was prolly around 5-6

How long do you inject CO2 to the tank (time)?

Nevertheless, That is too many bubbles per second. You should be aiming for 2 to 3, that should be enough.
