Thanks Dr. Awkward, It has finally started to balance out a little. My Ammonia and nitrates are still high, but I'll keep working on them. I just thought today that I need to test my tap water for Ammonia. I've tested it for everything else but that, but I'm wondering if that is contributing to my Ammonia situation. The crushed coral has been holding the pH 6.8 for two days, and with all of the water changes, the fish actually seem like they have a little more energy. My cories are darting to the surface every few seconds, and it's quite a distance (22 inches from top to bottom). I gave in and bought a juvenile albino bristlenose pleco yesterday and used the drip method (for the first time) to acclimate him. My semi-LFS sold me a drip line complete with valve attached. He is doing great. He started eating an algae wafer as soon as I put him in the tank, and he is active all day, which I'm not used to with plecos. I also bought two clumps of wisteria. I'm still on the lookout for more plants. With the low light plants that I have, do I need any kind of CO2 suppliment? I've been reading that CO2 lowers pH, and that's something I don't want to happen, since I just got it up a little!
As far as the wood, How long does it continue to release tannins? I've had all of that wood in the tank for at least 5 years. Does it ever stop, and for that matter, stop affecting the water quality, or will it continue as long as you have it in the tank?
I just read up on a plant that I didn't know about called African Bolbitus. It's supposed to be pretty easy to grow also. I think I'll look into that one also. Anyone have any experience with it?
