At a guess, your over dosing co2 and the plants can't use it so the algea is jumping on it

Can CO2 be overdosed? Wouldn't it kill the fish first?

Yea it happened to me on my 20gal. I didn't have the NV set right or I thought it was set right but 5HRS later everything dead 15-20 neon tetras, 2 glow tetras, 2 Siamese algae eaters, my 3 Cory's were weak and so was my yoyo loach. A lot of death that morning. When it's to high (CO2) you will see the fish gasp for air at the top of the water in the tank then after they will be floating upside down. If it ever happens to anyone n u catch it in time put an air stone connected to a air pump and get as much air as u can in the tank and either shut the CO2 off or turn it down.

Sorry to hear about your losses :-(
My fish are doing pretty good tho. No gasping, or weird behavior. So I think my CO2 isn't yet at killing levels.
However, my bobble counter is going crazy with too many bobbles to count. And the inline diffuser fills tank with lots of mini bobbles.
I am wondering if it's normal. Maybe for 80 gal tank it is how much is needed.
What you think?

Yeah, mine also grows huge and very fast too.

So I almost doubled the CO2 dose today. All fish still doing fine. Shrimps went close to the surface tho - that maybe a sign.
Will give it a week and see what happens.
Whole tank looks like filled with soda water - don't really like that much bobbles - maybe I should ditch the inline diffuser.
The idea was it would be more efficient and better dissolve CO2 - therefore I would need pump in less. But it doesn't seem to make much difference :-(

I'm pretty sure they are on the respective manufacturer pages, but if you want a specific one, PM me which one you want, and I will dig through my files.

If there are no fish then can you overdose c02?

So I recently set up a paintball CO2 with an ASA valve and a Watts LFA 41 needle valve...does anyone know why I'm unable to control the bubble flow with the needle valve? I've already killed 3 fish...possibly due to the fact that it either gives me like 10 bubbles per second or no bubbles per second...

It's the needle valve those are no good it's so hard to get the precision u need for 1-3BPS u can get it but its hard the easy way is take the diffuser off an put the end of the hose in water not tank water till u get the amt of bps u want then put the diffuser on and put in the tank.

No, but at some point, the CO2 you are injecting will just be wasted.

The needle valve (really, more of a flow valve) will not help control the CO2 flow rate to the level that we require in our hobby. I would suggest you get a needle/metering valve that is capable of reducing the flow to much lower levels.

If its still too high (co2 levels ) in tha tank what u can do is run an air pump with a stone for a little bit. That's only if u see the fish swimming at the top of the water once it's low enough they will start to swim lower in the tank.

I'm having a problem with my vts 253a. I'm not sure why but the blow off valve opened and blasted gas out really loud. My delivery pressure maxed out the smaller gauge so it must have been higher than 30 psi. Is there anything I can do to troubleshoot? Also, how do I close the blowoff valve after it's blown open?
