My biggest hold back is money. These systems mentioned like the dual 250 with VHO
O3 can be very expensive here. I priced out a PFO system and it is over $1100.00 CAN before taxes and shipping. So when I saw this MH
sYstem for so cheap($80.00 USD) I jumped at it to upgrade my lighting system. As it its right now I have no corals in my tank only one Sebae anemone and six fish. My tank is about 2yrs old an still in the building stages because of the lack of funds(It always seems to get diverted to the house). But one day I will have the big lights. For now I have to make due with what I have. I found through more research that I had situated the reflector in the wrong direction and have also added my PCs to my hood to help supplement the MH
. It doesn't look to bad now and i also see what you mean about the shimmer.
