sorcha Posted January 30, 2008 Report Share Posted January 30, 2008 Not sure if this is the right place to post but I am trying to raise the pH in my tank, have heard tufa rock is good for this & light, anyone know where you can get it from? Have also been using limestone, oyster shell, coral sand, our tap water is very acidic which doesn't help! Any advice appreciated. Quote Link to comment Share on other sites More sharing options...
Blackadder Posted January 31, 2008 Report Share Posted January 31, 2008 What you're already using should work, are you trying to raise it faster? You could use baking soda to get the pH of your tap water quickly to round what you want before adding it to your tank and keep using the shells, limestone or coral sand to buffer the water in your tank to stop it drifting.

sorcha Posted January 31, 2008 Author Report Share Posted January 31, 2008 Hi thanks for that Checked the pH last night and finally it was where I want it! lol, I had a tiny bit of wood in the tank so maybe that had been the problem. I was also wanting to add lots of rocks for hiding places etc but find that the limestone is really heavy which was why I thought tufa sounded good, but i've added some pumice which seems ok and is light Cheers Quote Link to comment Share on other sites More sharing options...
Foxglove Posted February 1, 2008 Report Share Posted February 1, 2008 Hiya, tufa is only slightly lighter than limestone - mostly because of the amount of hollows in it. You can drill holes in limestone if it is soft enough - make sure you wear eye/ear protection though. Pumice can look great - and can also be carved to suit. I have more limestone if you want it, including smaller pieces. Quote Link to comment Share on other sites More sharing options...
