For my 29 gallon I am thinking of getting either T5 HO, or PC. But since it is such an odd length, 30in there are no T5 HO fixtures at that length, but there are for PC. I am thinking of either getting 2 24" 4 bulb T% HO fixtures, or 2 30 PC 2 bulb fixtures. the T% would give it 192 wpg, and the pc 260. I plan on keeping some sps, some lps, and some softies. It will be a low to medium flow tank as it will be holding Seahorses. Any ideas are welcome. Thanks.
