Need help on MH for SPS

[Mao]

Good Day,

I have a 2x150w MH with 4x24w PL, if i change my MH buld(DE) to 'Iwaski' or 'BLV', can i keep SPS.....

Thanks....

as long as the bulb does not fall below 6500k in colour temperature.. it should do fine.

You can browse the lighting topics discussed before on the various important factors like lumens, spectrum analysis and PAR comparison of bulbs of different colour temperatures as these are important for SPS growth and colouration.

The brand doesn't matter as much as wattage. 150W can keep SPS but 250W or 400W will bring out the colour better and promote better growth.

There's more to SPS then ridiculously intense lighting.

Chris,

That's a good point I missed out!

Light intensity is important... 150w is able to penetrate less deeper compared to a 250w and likewise vs a 400w. With a 400w, you can keep SPS on/near the sandbed in a 2.5ft deep tank with no probs as the light intensity is still strong.

I hope that's not a dig at me!

Tanzy's right about that too.... you have a lot more stuff to go hand in hand with lighting, especially for SPS corals.

IMO, water quality is #1, that includes low dissolved nutrients, stable water parameters like cal, alk, ph, salinity and temp and good water circulation.

Agree with Tanzy,

Lighting is but one aspect of the numerous conditions required for SPS to thrive.

Thank guys....

When you are done installing your 6000W Carbon Arc lamp, then we can talk.

..........6000 Watts!?!?!?!? You can use that for suntan already...

6000W!!!!!

AT, since you live on the top floor, replace your roof with retractable glass roof for the full sun spectrum

If I install a 6000w, Raffles lighthouse can close shop!

With regards to sps i would say 70% to do with ur water conditions and 29% lights and 1% luck

Luck? What luck??

Seriously, they are all equally important. Lighting, water conditions/parameters and good flow/circulation. However, as Ming rightly pointed out, without optimal water conditions, your sps wouldn't last very long.

why not use the spotlight which Batman use, haahaa

Colour temperature too low. Not suitable for SPS.
