I'm putting together a 75 gallon setup hopefully for cichlids.... Malawi I'm thinking especially yellow labs. Anyway, I have well water and here are my test results.

PH 7.6
GH 0-1
KH 5

I've been using my well water in my community tank for 4 months now and it maintains the 7.6 PH with no problem but I'm wondering if I will have to do more like use some coral in my filter and maybe some crushed coral in my gravel as well? Thanks.

your water chemistry is not appropriate for African cichlids. the numbers you want for Malawi cichlids are:

pH 7.7-8.6
gH ( hardness) 160-280ppm
buffer capacity (kH) - 180-240 ppm

1° hardness = 17.8 ppm

you need crushed coral and some Rift Lake cichlid salts by Seachem or similar.
 
Here's some great info on setting up a Malawi tank:
http://www.malawimayhem.com/articles_setup_01.shtml

Here's a quote from that article:

"Malawi cichlids come from a rift lake in East Africa (Lake Malawi) that is very much alkaline (pH 7.5 to around 8.8) yet has relatively soft to medium hard water at best. (4-6 dGH and 6-8 dKH)."

You're current water is close. If you decided to use some buffering substrate, it would probably put you right where you need to be.
 
Thanks. I want the best conditions for the fish and don't want to try and really stretch the parameters. As long as I'm in the ballpark and can adjust a bit to get it near perfect I think I'll probably go for it. The last thing I want to do is try to do a major altering of my water to make it right which might not work in the long run.
Thanks for the tips and I look forward to hearing more, learning more and getting it right long before putting any fish in the tank!!
 
If you are within the limits (even lower limits) then I wouldn't spend time adding chemical buffers. It's more important to keep stable water paremeters, rather than constantly trying to achieve the "perfect" water conditions. Your fish will appreciate it.

Good luck!
 
What do you guys think of Eco-Complete Cichlid sand? I actually like the appearance of it and it looks like it will also help with the water parameters.
 
I had the eco-cichlid sand, and I liked it had no problems with it and it did help with my water.
