If you all started agreeing that T5's are better than halides i'm going to be pretty pi**ed off as i have just paid over £1200 for new halides.![]()
Id rather have halies. Less bulbs and less fuss imo.

216watts is plenty of light for corals and anemones on a 3x18x18 tank, but Tridachna clams will need to be out in the open to maximise the light they get. I kept Acroporas under 2 x 36watt T8 globes but the tank wasn't as high. It was only 12inches high but the corals did well.So can some one tell me ( ski? ) with 216w T5 power can i keep Hardy corals,Nems,Clams??? ect ect??? or am i going be limetd

Same unit, smaller wattages
With both Colin_T and BigC both saying T5 are fine for your set-up though, I'd say the choice realy is yours
Be careful with too much sand. More than 1" deap and you could get a DSB (Deep Sand Bed) filter forming at the bottom of the tank. If this happens, you need to take steps to enusre the livestock can't diturb the substate too much. The anairobic pockets, some report, caurse issues for the tank inhabitants if disturbed, though many argue this not to be true... With conflicting advise going round here, I'd play it safe and mesh over the bed if it's more than an inch deap, such that only the top 5mm or so can be disturbedAlternatively, you could keep it shallow
All the best

SPS = small polyp stony corals like acroporas.
LPS = large polyp stony corals like torch and elegance corals.
Basically it is the size of the coral polyps that determine if they are SPS or LPS. The larger the polyp, generally the less light they need. This is due to the bigger polyps being able to catch food like small fish and shrimp, whereas the small polyps have trouble catching anything and rely more on their symbiotic zooxanthellae. The zooxanthellae is the algae living in the coral's tissue and often provides the green or brown colour.
Corals with small polyps need more light because they are unable to get food from anything else beside the algae they have growing in the cells, (the zooxanthellae).
Plating monti = a type of coral called montipora that grows out in a flat round shape similar to a dinner plate.
then you have the job and cost of replacing 4 bulbs quite often. Id go for a 250W or 150W halide if i were you. You have 2 400W dont you? you could sell them for a fair bit i reckon
Yeah 2 400w halides . dont want much for them just enuff to buy smaller halides but no one seems to wan buy much as it comeing up to xmas time
