You can wedge a piece in your rock and over time it will encrust itself. If it's a frag on a plug it's easy, just glue the plug anywhere you like and watch it grow.

Heres my newest edition

72" aquamedic fixture.

4x 250 watt metal halide
4x 39 watt t5ho

That is beautiful. I love the rock arrangement and the new light.

Did you have to lose the canopy for the new fixture to fit?

Nope I opened the canopy and the fixture sits on top

so i was having problems with the lights heating the water to about 84F

so i installed 2 large computer fans to the back of the canopy and have decreased the temp to 80F while the halides are on.

i will be adding fans to the stand too and hopefully it'll bring the temp down a couple more degrees.

i also re plumbed the return to the opposite side of the overflow as i was finding that i had film forming on my water.
