Well I set up a 32g biocube for frags that is running and doing well. This w/e I set up a 90g tank and it is cycling now. I made 1 mistake in plumbing by putting in the uv in the back and will have great difficulty changing bulb(hope they last a long time). I am trying the 8x8x4 brick w/ rock in fuge, are they really that good. If anyone has a little chaeto I will need some in a while. The game has changed a lot since I got out, especially in lighting that is programmable, I will have happy corals. I got out for a while b/c one of my 6 kids threw pennies in a coral/fish tank and the results were not good. I appreciate the information and support from this group as I have been following for about 3 months.
