I have one nice 5" and there are a few 4-5" at my LFS.

Is there a site that lists the pros and cons of all three purification processes?

Is there a diferance between deionized and RO water? I was directed away from using RO water ratios to balance my PH by a LFS guy who has been pretty cool about giving me advice.

What is the least costly and or easiest way to reduce the ph to <7?

Do the parasites require dense confined breeding ground, or do they do best with some circulation of water. I have coarse river gravel .25" < .5", about 1.5" deap, and wonder if reducing the ...

I have a half a coconut, with a 3/4-1" hole, in my comunity tank, that come out of a well aged guppy tank. My royal will not leave it alone.

I have a community tank, that seems to have a fungus or similar infection, (fish scraping and a barb with a 1/16" gray patch).

I have heard that Loricariidae have a low tolerance for copper.

Is this true, and what other medication ingrediants should I avoid?
