New Tank questions

[Reef Tank Engineer]

Try to get 1 pound of rock per gallon of aquarim water
For lighting 2 t5 good for fish only, try to aim for somewhere between 3 to 5 watts per gallon for a reef tank to keep corals happy and growing get bulbs in the proper colour temperture a 10k or higher and a 470nm or 460nm pure antinic bulb will be fine.
If u use a canopy u may have heating issues and may need to add a small fan for additional cooling.
I have 4 55 watt t5 over my 90 gallon reef with a diy led fixture
All my softies, lps and two anenomes are all growing rapidly with polyp and tenticle extension.
