<br>

My experiences with cichlids have so far only been in Americans but I want to start planning an African tank for Mbuna. My tap water comes out with a pH of 7.4 which is great for my Americans but I will need to achieve a higher pH for Malawi's so my question is if I use coral sand, crushed coral or some kind of rock to buffer up the pH will this achieve the desired pH and stay at that level on its own or will I need to still add salts/bicarb etc on waterchanges? Also will the effect of the coral substrate deteriorate over time?

<br>

cheers

from my personal experience the coral sand has been a great buffer no deterioration in levels or changes over time hope this helps... also have heard that chipped marbel is ok and cheaper too good luck .

<br>

I'd recommend either shell grit or chipped marble (marble sand) over coral sand.

<br>

<br>

Coral sand is expensive

- and there is no real difference between these substrates.

<br>

<br>

Best place to buy marble chips or marble sand is Mini-Crete in Lakemba.
