Hi,
We've got a 50 gallon well planted tank on the go at the moment. I'm hoping to add co2 to it soon but have an issue. The pH is about 6.5 and as I understand it will get even lower when I add co2. I don't want the pH too low as it'll upset the snails...
Apart from plants there is a "clay" gravel and some slate as scaping. I've come to the conclusion that the slate is reducing the pH. Would anyone else agree? I popped some slate in a jar of tap water and tested the pH a few days later and it was very low. I was surprised as I'd assumed slate was inert.
The tank looks pretty good and I'm really loath to take out all the slate so I was looking for advice as to how to raise the pH. At the moment there is a net bag of shell chips in the filter which has made no impact.
Cheers,
Su
