I'm in the process of setting up my new 130l tank and I'm going to have a crack at a low-tech planted aquarium. I picked up some driftwood, plants and a piece of ocean rock on my way home from work today. I never really thought about the effect a rock would have on water parameters, but as it was called 'ocean rock' I thought I'd have a quick Google just in case.
It looks like it's a good job I did check, because I discovered the vinegar test and it did fizz. However, I'm still a little confused because there's quite a lot of contradictory information out there. Some people are saying to give it a miss because it will raise PH levels, whilst others are saying that's only an issue if you have a low PH beforehand.
My PH is already 8, so does that mean the rock would have no or very little effect, or will it raise it still higher?
Thanks for your advice
