Wow cool bro! Can't wait to see your diy led set. I'm using par 38 too (4x blue, 4x white & 4x green). I bought it from eBay.. wanted to save cost as well.. $$

Bro if your interested in marine snails (what algae they feed on etc) you might want to refer to this link ( http://joejaworski.wordpress.com/2013/10/03/whats-the-best-snail-for-a-reef-tank/). I got all the info from there.

Was told they are reef safe so I bought them today. I did a research when acclimating them and realised they are not exactly what I was told.
I think it's better to be safe than sorry. So I'm hoping to give them away ASAP.
PM me for more details. Thanks.
