So I am running HQI MH's on my 20G long, currently using a simple retro kit reflector. Looking to switch to something else, space is an issue, with that in mind I was at first looking at the lumen brights but i think even the smallest is a little too big for my tank. the lumen max seems to be a good size. the dimensions of the tank at 30Lx12Hx12W. Anyone have experience with the lumen max 3? or can recommend any other mh reflectors? Dont want to spend the money on LEDs with my current setup. t5's I might do but atm would like to explore mh's more.
