Actually...am I right in thinking I need to first decide what type of fish I want in the tank and then set the GH? Fish like Neon Tetra's seem to want a very low GH while fish like the Zebra Danio need 5-19 GH. That would seem to indicate that trying to keep those two fish in the same aquarium wouldn't work out that well for the Neon? Well provided that GH was set for the Zebra that is...however I think its always better to go with the higher GH than the lower since the Zebra simply couldn't get the minerals it needed from the softer water right?
