CO2 and cherry red shrimp careful!

I gradually added CO2 to my shrimp tank, and ended up losing quite a few. I gradually lowered the ph over2 weeks. My conclusion is that it's a bad idea to use it with shrimp.
Thoughts?

Did you shut off CO2 and let it all gas out before adding the shrimp in? If you didn't that iwll kill them gradually.

Another reason could be that you ramped up the CO2 too quickly which also can kill the shrimp. It needs to be very slow after the shrimp are successfully acclimated.

But yes, CO2 is quite harmful to shrimp.

As long as you shut it off a day before and gas all the CO2 out (by turning on a bubbler) before acclimating the shrimp there won't be a problem. Make sure you slowly ramp the CO2 back up. SLOWLY. Also, at night you want to make sure not to gas your shrimp so either shut off your CO2 or if that is too difficult then put a bubbler on a timer. If you follow all of those steps your shrimp will be fine with CO2.

I started without the CO2 for months and gradually added via regulator and bubble counter. Over two weeks I increased the bubble count and then a die off. Conclusion, careful with CO2, best not to use it in a shrimp tank.

Did you turn the CO2 off at night? Do you have any surface agitation?

two words DROP CHECKER . I haven't lost a shrimp in any of my tanks with co2. A bubble counter only tells you what you are putting in the tank not what is being used. And if you left the co2 on with the lights off that is your problem.

I have DIY CO2 on my 10g with RCS and they are all doing fine. (was added after the shrimp had been there for months) Its only running about 1 bubble/3-5seconds but the shrimp are still making babies like rabbits.

co2 isn't bad, people that don't understand how to use it is bad.

Excel is the same thing use to much and every thing dies , pretty simple


people need to use common sense , with dosing any thing that goes into a tank

Excel is perfectly safe with shrimp. Unless you overdose 10x the amount you won't have any problems. Just try not to dose on top of a shrimp :P

If you do it right, CO2 will not cause deaths. It needs to be balanced. You can't just crank it up, and forget about it.

You have to slowly over time, for me it's about a week increase it until your shrimp are ok plus your plants are happy.

Currently my gf and I have a 12G CRS tank that we dose CO2 24/7 with .5-1bps and eveything is doing just fine, they are even breeding and very active. Got 1 prego shrimp so far and we are talkin about SS-SSS CRS here.

The problem would most likely be the inconsistency in the pH level. Keep it as constant as possible and you should be fine. DIYs are more risky because you really can't control the CO2 output.

Thank you for all the comments. The problem it seems, was in the bubble counter exit port being clogged. The bubbles expressed small and slowly and were less noticed. I've cleaned it out and now see much more "crisp" bubbles, starting at 1bps, and increasing 1bps per week
