Add a few small pieces and monitor the pH over a week
Hi colin
Ph is the same at the moment after adding a couple of wheels to the tank. I've put a background on, not sure if fahaka likes it or not. Here is a updated video

Add a few small pieces and monitor the pH over a week
OK thank you, just added 4 sells at moment.. What sort of limestone can I add. Would cotswold stone which is limestone be OK. Or are we talking about ocean rockThe puffer appears to be a bit unsure/ wary of the back of the tank now. It will settle down in a few days.
It takes a few days before you see any change in the pH if it's going to change. Just monitor it over the next week and if the pH is still low, add a bit more limestone, coral rubble or shells.
I have no idea what Cotswold stone is.
Just use normal plain old boring limestone. If you can find some nice smooth pieces at the beach they will work. Just rinse them off under tap water and add one piece at a time.
Make sure you are not to take stuff from a marine park.
Unfortunately I'm 3 hours from a beach lol, so it's shops or garden centres onlyI would just go to the beach and find a couple of bits of limestone and grab them. try to grab the dry stuff not the stuff in the water, which could have marine life on it.
Pet shop that sells marine fish will have some. Otherwise a garden centre or hardware store but make sure they haven't sprayed it with any herbicide.
