Hey guys, I'm totally new to this hobby. However, I have done several months of research. My current set up is a 20 gal
. tank, a marine penguin HOB
filter, a koralia 600, 4 pieces of live rock (ordered 15 more pounds), a 2" live sand bed, heater @ 78-79 degrees, 3 hermit crabs, and four snails. I ordered a fluval 206 that should be here soon. I was wondering what else I would need for the set up. Also, I bought ocean water, and was wondering if that means that the tank wouldn't have to cycle. However, I think the tank might be cycling anyways because the ammonia has spiked to 0.25. The pH dropped from 8.2 to 8.0, and the nitrates and nitrites are remaining at 0. Any help would be greatly appreciated.
