I've got it under a 4 bulb t5. The bulbs are pretty dang old though. Should I set it down on the sand or leave it up high? I have moved it 2 other times and it seems to like more light. I feel as though I don't possess the skills necessary to care for it. Nor the equipment. I have a sump with some carbon in it and I'm trying to get a handle on some chaeto. But I'm in a small town 3 hours from any real source of marine supply and shipment in the winter has already killed one order of chaeto. I have a hob skimmer which I will upgrade sooner than later but still. The only things I have living in there right now are some snails, hermits, 2 peppermint shrimp, and an Rbta. I made a mistake in buying my first fish before doing research and got something too aggressive so I got rid of it. All water parameters are ok I think; dKh 9.5, Ca 410, Mg 1400, ph 8.1 and the nitrogens are all 0. Thank you guys for the input!
