I went with special grade reef sand in my new tank and like it way better than sugar size. Way less storms especially if you have a sand sifting goby. I have one area in the tank that the sand would disappear from , so I added a cup of Crushed coral and it solved that problem.
Not sure of your requirements , but I love my radion LEDS.

Radions are wonderful but I'm a stay at home contractor so those aren't in the cards for er awhile.
unless someone needs some design work done har har har

Oh! That's the 24X24X24 one that was on Kijiji right!? I was seriously considering it! Take photos when you get it set up, please!!

Go for it provided you do not add heavy fish like tangs.

Nope this is the cube off out of Steves store it's even better.
tangs weigh at least 600lbs each I'd have to be crazy!

If you can use a solder iron then you can make a better Led fixture for a fraction of the cost. Http://aquastyleonline.com

If you're really worried and can't check the joists, you could add a sheet of plywood on the floor before setting up the tank to help spread the weight. However, I don't think it is going to be an issue.

For all the threads started on fish sites about this weight of fish tanks & floor strength issue, I have NEVER heard of one case where a tank actually going through a floor. NOT a single one and I've been keeping fish since the mid-70s. Yes, too much weight can cause floors to sag if not placed properly perpendicular over the floor joists, but yours is small enough & light enough it shouldn't be an issue.

yeah me neither urban legends I'm suspecting. I can use a soldering iron so those lights are what I was looking at.

I've built two of these kits and it was fun and easy. The hardest part was getting the fixtures to fit within existing hoods but you will not have to worry about that.

i have the aquastyle kits too the only thing i dont like about them is the rehostats , they dont seem to dim on a consistent curve . Once i pick up a few better ones they will be perfect.
