Shrimp And Co2

[SLIM]

Do shrimp and co2 mix?
Some online content suggests its ok
Other suggests co2 kills shrimp.

Co2 kills shrimps just as it does fish........at certain levels. If you are running the CO2 properly at a safe level then neither are affected.

Fantastic! Thank you supercoley

OOh sorry one last thing.
I also read that the PH swing when the co2 switches on n off can also kill shrimp, is that true?

?

I don't have CO2 but I know that pH swings are bad news for shrimp. Some varieties are more delicate than others. For example, the Crystal Red's and Sulawesi are very sensitive to everything and can die at the drop of a hat.

So i guess the answer is no then?
Co2 and shrimp dont mix.
Thats a shame!

Shrimp and C02 do fine. As Andy states, you just have to monitor it.

The Ph swing caused by CO2 is irrelevant to a fish/shrimp. Ph swings are not important at all in reality. It is more the KH that matters and that can normally be measured in effect by the Ph as they can be related however in the case of Ph changing due to CO2 the KH will not change therefore not a problem.

I run CO2 very very heavy in my main tank and the shrimp colony is in the region of 1000+ and breeding far too succesfully. the Ph will swing from 7.4 down to 6.2 with the CO2 on. Not a problem.

CO2 can be dangerous to all life forms if it gets too high however many people make incorrect correlations.

So summary. Ph swing bad for shrimp/fish Yes if it is linked to the KH swinging with it. If not linked to this then nothing to worry about. If it were we would not dare put woods into the tank, would not dare to change large amounts of water etc for fear of the Ph altering.

Brilliant just wanted to hear. Dont suppose you wanna sell me about 20 of your shrimp do ya?

A little bit busy at the moment with ew baby. Sold 500 already this year. Will start again in a month or so

Great, gimme a shout when you do.
Congrats by the way. Thatll be me in 8 weeks.

That's interesting, I didn't know that . That must be what's happening then when you hear of shrimp getting wiped out in planted, CO2 tanks. Will pass on the word . So I just want to confirm; pH swings are no big deal? It's the KH that's the problem? Do they always "swing" together then or are they two separately occurring things?

So I just want to confirm; pH swings are no big deal?

Not massively. Definetly not when its caused by CO2

It's the KH that's the problem?

Something to be aware of yes.

Have a read.

If the KH changes the Ph will normally go with it....normally. the 2 are independent of each other however they do tend to walk hand in hand.

With CO2 the Ph drops. 30ppm will drop the Ph much less in a higher KH tank than in a lower KH tank. Still 30ppm though. This is why we often read that CO2 causes Ph crashes in low KH, however many scapers are banging the CO2 in with KH of zero with no ill effects.

So its quite simple really. watch fish/shrimp for distress with CO2 addition. if you see it then most likely cause is too much CO2, KH a far second.

If you are worried then take the Ph after a water change and use that as a benchmark, take it 4 hours after CO2 starts and use that as your second benchmark.

You then have a rough max and rough min to measure to. If it goes past either of these too much in either way then you can start checking more often.

For me its much easier to just watch the livestock

So, what if you're not using CO2? Do the pH and KH go hand in hand in the same way?
