I've done acrylic with MH and never had a problem. Just make sure to suspend it a reasonable amount above the lids.TankBuster;673825;673825 said:Just a quaick note, make sure your fish will and can tolerate the bright lighting of the power compavts. I also dont suggest metal hilides on an acrylic tank because the extreme heat will cause the top and lids to warp badly. I know this from experience. The top of the tank that has the cut out openings have warped on my old tank a good 2 inches higher.
Actually High Output T5 bulbs have a higher lumen rating, and high lux rating than MH, and are much cheaper.Boydo;673746;673746 said:Power compacts are nice, they have a new bulb out thats 50/50 ( 6700K / Colormax ) looks great. If you want brighter theres always metal halides which are the brightest per watt, and the most expensive.
