I finally convinced my girlfriend to buy a bigger tank!!
But I got a few question since I'll change from 20g to 90g.
In my 20g tank I got enought liverocks (25 pounds) so I didn't use skimmer. Only a small AquaClear 150 filter with Carbon and sponge. It's been over 4 months now and my water is excellent.
So I'm wondering if I can do the same thing with a bigger tank. If I have enought LR
(let say 110-120 pounds), is it possible to maintained good water parameters without to need of other kind of filter or skimmer?
Second question. I'll keep my 20g tank as a quarantine tank. As it will stay in my living room, can I keep what I actually have in it (LR
, few corals, snails and crabs) or I should remove them?
