Nano advice

i bought 2 bags of sand for my tank...

but my next will be all dry and seeded with a scoop of my selection live sand.

i ran bare bottom last time. i plan to do it again. i might put sand in the bottom of my or two of my tanks. what you could do is make/get and overflow and a return pump and use the 30 gal as a sump or refugium for now... use egg crate and cable ties... you can run a DSB and cheato in there and it wouldn't be so hard to keep it stable... if you don't want to use your 30 gal. you could get another tank for cheap or free somewhere...
just my $0.02

also you can buy loads of stuff (including LS) from GARF.org they are REALLY good and also tell you how to frag coral or you could buy some from them...
