20 Gallon Tank Can you keep a German Blue Ram with CO2 ?

[Mark2621]

My favorite fish is German Blue Ram. I want to get one for my 20 gallon, but I'm worried becuase my tank now has Co2. I was reading that German Blue Rams are very sensitive to PH swings, and my Co2 causes my PH to swing from 7.2 to 6.2 every day when the Co2 comes on.

Can I still keep a German Blue Ram or is this too risky?
A backup plan could be a Betta fish, but I really love the way a German Blue Ram has a ton of personality and chases your hand begging for food.

Any other fish suggestions that have a lot of personality and aren't super sensitive to PH swings?

First of all do you have a bubble counter...
What mesures do you have to check CO2 concentration in tank...
What kind of diffuser you are using...
If are unabla to tick all these boxes...
Then probably it will be better you dont do fishes in that tank.
Like in aquarium of that size... flux diffuser should be used
Do you have a precision needle valve
If you are planning to intoduce a fish. Your CO2 concentration should not exeed 30ppm...
Guppies, mollies and swordtails can thrive n high PH.
But I dont believe there is any fish which can be comfertable with sudden PH Changes.

Yes, I have a co2 drop checker, and the color is green.
I'm using a small ceramic diffuser designed for a smaller tank.

I don't have too much co2. My drop checker is never yellow.

However, every time my co2 is off at night, my PH is 7.2
When my co2 is on during the day, my PH goes to 6.2.

Will this daily PH swing caused by co2 harm my fish? Specifically, my German Blue Ram?

Fishes are not good with sudden changes...
You can try with mollies, guppies, sword tail and all...
If you want you can take your chance....
