Hi, I'm new here and last night decided I want an African Cichlid tank. So I started setting up my 55 gal. I cleaned it out and rinsed off about a 5 gal bucket worth of sand and about a 5 gal bucket worth of crush coral that had been sitting for 3-6 yrs and put that in my tank. I also put some rocks in there, but I'm not liking the look of most of them. So my question is...Can I use reefs and live rocks (no longer living) that have been out of a marine tank for about 6 yrs in it? I'm wanting cichlids from Lake Malawi, not real sure about which group yet. We'll probably go to a store and look at the different types soon and start trying to aim at getting the ph and temps to which I chose. I know I need my tank to be running at least a month before adding fish.
We currently have the following tanks....
10 gal in the kitchen with a few female guppies, platies, coolie loaches, cories, baby kribs, and an African butterflyfish.
125 gal in the living room with kribs, a leporinus, pleco, covicts, oscars, fire mouths, and gorumies (sp?) The covicts, oscars and fire mouths were just added over the weekend.
We will also be setting up a 30 gal reef tank later. And are helping my daughter's kindergarden class set up a 10 gal comunity tank and may look into setting them up a small reef tank for a short while.
