Is this light settings suitable for SPS only tank ?

[Verti]

I have 2 MH bulbs. 250W each. 14,000K.
My tank is 70 cm high. SPS will be set on all level (even near bottom).

Is this light settings suitable for SPS only tank ?

I think you'll be OK. If you find that the 14K isn't bright enough, you can switch out to a 10K bulb.

You'll be fine. Any 250w bulb is enough for SPS. Keep in mind that you need everything else stable for keeping SPS. Lighting is just one piece of the puzzle.

Actually, I would like to switch from 14,000K to 20,000K.
I understand (correct me if I am wrong) that in 20,000K algea will not bloom as in 10,000K-14,000K.

Anyway,
Alk level - 9.8 dkh (trying to get it low to 9.0)
Ca level - 420
Mag level - 1380
NO3 level - 2 PPM
PO4 level - 0.02-0.04PPM
Stream - 2 Vortech MP40 - great water stream
Temp - 25.5 c
Salinity - 1.025

Algae shouldn't be blooming under a 10-14K. That would indicate a water quality issue. Try lowering your nitrate and phosphate.

i used a 150w ushio 20k bulb on a 20 inch tank with less than an inch sand bed. this frag was completely brown so i brushed it aside and left it there on the bottom left side at the front of the tank and i just discovered this after scraping my algae. i dont remmember ever buying this. point? yes, your lighting is way sufficient for sps on the bottom
