Well I finally got sick and tired of the Coralife legs on my 2x18watt fixture. They never fit well in the first place, and lately have begun slipping all over the place including falling completely off. Considering that it can get a bit warm while the light is on, I'd find myself juggling a hot potato until I could get it put back together so that I could put on the tank or ground as the case may be.
Today I used some 1/2" CPVC to build a stand. Cut 1/4 groves lenthwise in the front and back horizontal pipes for the light to sit in and then notched 1/2 of the bottom pieces so that it hugs the rim of the aquarium. I'm very pleased with the results. It's much sturdier and easier to handle than before. I still plan to see about getting ahold of some black paint and then it should look really sharp.
Anybody want some used Coralife legs?
