This is the situation. I have an established 15G at the moment. Lightly planted with Java Moss and Glossos. Then my girlfriend wants to give me a bigger tank (30in x 18in x 18in - how many gallons?) I'm planning on switching all my plants, substrate, driftwood, water, etc from the 15G to this new tank. This is pretty much a no-brainer, right? Just take all the stuff from one tank and dump it in the other tank. I'm just checking with you guys first before I do anything.
