I recently setup a shrimp tank. Right now I only have RCS but want to get CRS too. I used aquasoil because it is supposed to lower the pH and hardness of the water. My tap is 7.6 but when I put it in the tank with the aquasoil it drops to 6.4 I tried adding buffer this moring which temporarily raised it to 7.5 but it has slowly dropped throughout the day and is now at 6.4 again.

Does anyone have experience with aquasoil or a way to keep my pH up?

Will my shrimp be ok at 6.4?

lol... you got ada to lower ph, but now you want a high ph?

I don't want high pH but I would like it between 6.5 and 7.5. 6.6 or 6.8 would be great. I had no idea the aquasoil would drop it that much. I thought 7.6 was too hight and now I'm worried that 6.4 is too low. Is 6.4 ok?

If you've just added AS, you'll need to do lots of water changes in the next couple of days. AS won't lower the pH that much once the parameters are stable. Test your ammonia.

Oh, 6.4 should be OK for CRS anyways.
