That's because unless the Thai LFSs have a CITES permit (which they don't), all stony corals are banned in Thailand.

With the very reasonable price and wide variety of choices for chillers in Singapore, it would be a travesty if you settle for cooling fans instead of a chiller. Take a look at the sponsors threads in SRC and you'll find everything you need to stock up on fishes, inverts and corals.

Algae blooms and cyanobacteria will occur and grow more frequently with higher water temperatures. Fishes are also less lively in a warmer tank and many corals including softies won't "open up" so much. Best to install a chiller sooner or later.

Because the brown and green corals are cheap. And Malaysian reefers don't want to pay extra $$ for better looking livestocks.

They will never be sold in Malaysian LFSs as long as the malaysian reefers continue to be happy with brown and green corals.

Have spoken with the reefer on this - he's got everything spec out for me. Like you said, will be fun.

Point noted. Will place accordingly.

The bulb casing comes with a GLASS cover to protect the bulb from splashes.

All MH bulb are encased in casings so no worries about splashes.

Thanks. I won't be using a commercially sold chiller, will use a custom-made chiller with an air-con compressor sitting outside the house like a split air-con unit. The compressor will be a 1.5 hp unit. One of my reefing friends have this unit done up for his 210 gallon tank and it's worked very well for him.

Will increase it to one hp then. Wrong use of words - it should read intensity, not spread.

Good idea - I will place the 150Ws at 4 inches above the water surface for a better spread. Will place some wooden beams in the hood to accomodate this change.

If my current resun 650CL can't cope with the additional heat, I'll retire it as a back-up chiller and get a custom made 1/2 hp to do the job from an air-con man who's experienced in making chillers with air-con compressors.

Thanks for the feedback, fellow reefers. The MH bulbs and fittings have already been bought so I can't change those without considerable expense. The tank has yet to be ordered - I'll raise it to 24 inches then. Won't be keeping any LPS - just SPS and mushies (yumas, floridas, discos etc).

Dear fellow reefers, I will be placing a 10KK 400W XM bulb and two 15KK 150W XM bulbs supplemented with two T5 actinic bulbs over a 42 inch (length) X 30 inch (depth - front to back) X 21 inch (height) future tank. Bulbs will be placed 8 inches above the water surface. Top two-thirds of the tank will be devoted to SPS corals (mainly acros) and a single crocea clam. The bottom one-third will be yumas, floridas and other types of mushies. Bare bottom. What would be your recommended photoperiod for these three MH bulbs and actinics? My thoughts is on 8 hours for the two 150Ws and a 2-3 hour photoperiod for the 400Ws to simulate the noon sun. actinics one hour either side of the 150Ws photoperiod.
