Goodbye GHA!
Well ever since ive owned my 33 gallon aquarium ive struggled with HA here and there. Ive ran a 4x T5HO light fixture and played around with bulb colors trying to get a combo I liked as well as changing the bulbs out every 6 - 12 months (whatever i can afford at the time). Frequent water changes, blasting the live rock with a baster, growing cheato, phosban. Nothing was ever a quick or easy fix.
Almost a week ago I switched my lighting to a single 250w MH fixture and loved the color and shimmer of the ebay 20000k. Days later I noticed almost all the algae in the tank slowing disappearing! Melting off the CPR overflow, off the PVC intake, off all 4 panes of glass. The light schedule shuts off a couple hours earlier but Im convinced the lights had a much bigger influence on the HA growth than I previously thought. I cant afford to change my bulbs every 3-6 months so Ill defiantly try this out for a couple months. Corals are happier than ever as well. My only complaint is of course the heat but ill add a fan to blow over the surface when i make a more permanent stand for the fixture. Anyone have a similar experience with HA and light setups?

I have 2 tanks, one with MH and one with T5HO, and it is a striking difference how much more beautiful and happy all my corals are under MH, wereas the color and thriving is very low in under the T5HO.
I keep T5HO under my other tank because it is a nano and the heat would be hard to control, but nothing beat MH  I have pink and gold paly in my MH tank that are really gorgious, bright golden yellow in the center with very saturated pink tentacles, but when ever I sell frag to people without MH the polyps always become brown. Even those with LED cannot keep the pink and gold color! I don't know what's in the MH that give them that beautiful color but they obviously because very dull and brown under any other type of light.

absolutely agree, Everything appears to glow, especially my green zoas Time to get some new frags and see what other corals look like under this light
 I have thought about LED eventually but I want to run the MH train for awhile and gain some experience.
