Crushed Coral, Sand, and African Cichlids
 
This is my first post on TropicalFishKeeping.com, so I hope I'm in the right place. First of all I have 4 tanks, a 30 gallon long, and 30 gallon tall, a 75 gallon, and now a 165 gallon. As of now my 75 gallon is full of Malawians, which I am using common aquarium gravel. I am getting ready to move these africans to my 165, and I am going to use white sand instead of gravel. My question is, I have a 2 gallon bucket of crushed coral, when I say crushed coral, I mean these are in 3/4 to 1 inch chunks, I am considering burying the crushed coral under the sand along the back wall of my tank. Other than the africans doing a lot of digging, would this be worth my effort with the coral buried in the sand to help work as a PH buffer?

If you are using tapwater now, and cichlids are doing well, then I would not bother with the crushed coral. Weekly water change with the tapwater you have been using should provide the minerals ,buffering, needed.

Putting the coral into the tank will help with your pH. Even if you tap water is good, the coral will help you keep it where it needs to be.

Get a mesh bag and put some in your filter - works a treat, as the flow will slowly break down the coral and release the minerals into the water, keeping it buffered.
