Here are the choices I've made. It's between two different setups which will cost roughly the same amount (within $10):
6-T5HO 39w retrofit:
3-Workhorse 5 ballast
6-reflectors, bulbs, endcaps and standoffs
This would be relatively low heat and efficient system with the ability to mix and match various bulb temps. Using three ballast would enable me to set-up several different on/off combinations.
1-250w MH w/2-T5HO 39W actinic supplimentals:
1-250w Icecap electronic MH
1-PFO Parallel 36" reflector
1-PFO Mogul socket w/cord
1-250w XM 10K MH
1-2 bulb T5 retro kit w/bulbs
What's your opinions on these setups? The tank is 36x18x20. There will be a 2-3" sand bed reducing the depth to 17-18".
