Axe the pH buffer. In 99% of the cases it's not needed and you do *not* use chems to "fix" pH. No chems in tank. Condition water. That's it.

A bigger tank is easier to care for than a little tank. I'm gotten rid of all my tanks that are under 20g, except for my two 10g QT/Breeder tanks.

Ten gallons is too small for even ONE goldfish. You need at least a 30g tank for two Fancy Goldfish and a 40-50g tank would be even better.

Your common goldfish can grow 12+ inches and it needs to be in a pond. They really aren't suited for in-home aquaria at all.

Hope that helps

Leave the chemicals out, know your source water and maintain the enviornment for your fish. All those items that "do things instantly" are kind of like the "weight loss" pills" that burn fat while you sleep.

:OT: I would say, not in relationship to aquariums in any way, you can control pH of a liquid system with chemicals, but it doesn't create a livable enviornment, as most primary and secondary systems in reactors will attest to.
