opinions on subtrate in your nano

[dino]

Lots of debate anything other than nano id use sand but nano id say bare bottom

[Myka]

What do you consider a nano? I've used Caribsea Reef Select in all sorts of tank sizes from 5 gallons and up. I don't think the size of the tank matters so much as the amount of flow and the livestock going into the tank.

I'm barebottom on my 20 gal. If I had sand in it I'd have huge dunes and barespots from the wp25. The 3 Koralia 425's I had previously didn't affect the sand too much but they also didn't move the detritus into the water column. In a small area it's tough to get the perfect amount of flow so barebottom is just what I find easiest.

does anyone have any experience with crushed coral for subrate in a nano?

I would say crush coral is a bad choice for nanos. Because most of the time, people would keep fishes like gobies in nano who are prone to getting scratched from crushed coral. Look at aragonite special grade. Big enough to stay in place.

very good point on the gobies, I will probably have one in there too! so top ideas will to be no substrate or to do a thicker
sand.

Depending on the goby you will need ti have some kind of sand for them to sift thru... if its that kind of goby
