Funny thing... I have an ATO that I bought when I picked up the tank but haven't hooked it up yet. After adding the lid (which still has a gap for gas exchange) the evap has been negligible but is probably still more than is desirable for some corals. Thankfully at the moment I work from home so I check the water level three or four times a day. I'm definitely not getting into anything difficult yet. I am too new at this. So far I just have some gorgs, a xenia and a gsp and I've been adding them slowly making sure each piece is doing well before I think about adding more.If you're new to the hobby and have never had a reef tank before I reccomend starting out slow with a few mushrooms and maybe a plug of zoas or a pulsing xenia toadstool
Once a week is most likely fine unless you’ve got more than one small fish. I don’t think small tanks are really that difficult, there are certain considerations and you should only put hardy species in it, but a 5g can be pretty easy. Doing a 50% water change once a week should keep most of your levels fairly stable (may have to start dosing Alk and Cal). IMO, you’ll likely never need a skimmer or reactors, some media in a filter bag in filter would be just fine, most people don’t put skimmers on a 5g because it’s ineffective, especially when large water changes are so easy. Just try to keep things stable, and your corals should do well.Ironically I did put on a lid a couple months ago and it slowed evap a lot. I only have to do a minor topoff once a day now. I have been doing larger weekly water changes but have been considering doing twice weekly smaller changes which pretty much is in-line with what you mentioned.
Thanks for this! The water changes seem to be enough for now and as it is I don't have room for a skimmer even if one would be beneficial. LOL. I barely have room for the 5g. It's an AIO (Top Fin's version of an AIO) so I have room to put media in the second chamber. Right now there's a baggie of MarinePure Gems but I have room to add more media if needed down the road.Once a week is most likely fine unless you’ve got more than one small fish.
