Rock for rift lake tanks

[Hawkman2000]

I will be setting up my 37 as a tang tank soon, and I will be lokkibg for some rock to stack that will bring the ph up.

I found this on amazon. Dont know if it will raise ph. Posted question on listing on that. Looks good though.

I have also been reading mixed responses on whether or not lace rock raises ph.

If it's mined from Florida, it's almost certain to raise the pH.

I've used this stuff and lace rock for African tanks. I prefer lace rock only because its a bit stronger. IME, both rocks broke down over time and became brittle. Nothing where I was afraid of anything collapsing, only when I did a WC and rearranged rocks. pieces would break off. Also, both types of rock have sharp edges. I stopped using them because the fish kept scratching their eyes as they tried to escape from aggressive fish. What Tangs are you planning to keep?

Dont know yet. A guys at Fishy Business is gunna help me figure out what to put in it. Also seen that there are alot of old world breeders here in central florida.

Gunna some tough choices since its a 37 tall.

Cool! Be sure to do some research!

Easiest way to tell if rock adds to pH / hardness is to drop some vinegar on it. If there's bubbling and fizzing, then there is CaCO3 (Calcium Carbonate)...

How do you put vinegar on something on Amazon.com?

I was originally going to use lace rock to raise the pH because I like my white PFS. but the guy at Fishy Business said it doesn't raise pH, and I have read conflicting info on it online.

I have a few pieces so I'm going to put them in a bucket of water for a week then test the pH.

I have had good success with the Carib Sea African Cichlid white sand. It buffers the PH. I also worry about lace rock due to the sharp edges. I stopped using it. I only have Tangs.

+1 for Carib Sea for African Cichlids. That is the only substrate that I use. I have used different colors and sizes.
