my approach to nano tanks is that a skimmer and wetdry is unnecessary and only complicates teh set more then necessary.. either way a nano requires alot of attention so its much easier to just do a weekly small water change then to deal with skimmers and sumps and wet dry .. most back pack skimmers do a mediocer job at best except fotr maybe the cpr but thats not really a cheap unitIt's got a skimmer and wet/dry......are you saying the wet/dry wouldn't be good? I don't get it.
The only things going in the nano would be a few seahorses, like 3 or 4.
you might be better off just getting an aga tank then get a large aquaclear filter and swap out the impeller for a smaller one to slow downt th flow and turn the filter into a refugium, very good for these type of setups to allow for the growth of iso pods with are very benifical for most marine animalsGotcha, I'm sure that 2 would be fine in a 24gal cube. I've been pricing it out and may just go ahead and get a 29gal for them.
