Tips for a discus newcomer

Greetings all,

I'm starting out with a new discus setup (a 25 gallon tank set up with peat
substratum, low Gh, low Kh, slightly acidic water with pH at 6.6, marineland
exterior water filter). The tank is now being cycled with a small tetra
population (6 black neons, 6 serpae). I'd appreciate any pointers as to what
are the best practices after cycling for helping to provide a low-stress
environment for my fish (I'm holding out two weeks before transfering the
cychlids from the dealer, a pair of blood pigeons).

Thanks in advance

Carlos Pires.
