my lighting and sps

Anyone that can spread any light on this would help me

This is what I have
75 gal
1 54w bulb - Ocean sun 10,000k t5ho (strong emissions in the blue range)
1 54w bulb - ultra sun super daylight 6,500k
2 54w bulb - coral sun actinic 420 t5ho

Is this enough light and right combo? I have a favia and open brain sps and 3 soft corals. I would like to add one more sps in a few months.

Suggestions?
What would I need to add if I were to add a clam?

 

listing the lights doesnt helop, what type of lighting is it? t5, pc, halide, led??

 

OP posted that the bulbs are T5HO. (Look above.)

You should be able to keep SPS fairly well with those bulbs. What fixture are you running? Does it have single lens reflectors or is it one big one?

 

i would not keep many sps, they need a larger fisture of t5's, at least 6 bulbs with individual reflectors

 

A clam like a squamosa should do fine on the sandbed, but if you wanted a maxima, which needs more light, it would need to go higher up in the tank(on the rocks).

 

i would not keep a clam under those lights, also dont put one on the rocks. if it fals it would be fatal for it

 

One is a coralife the other Glo - both are second hand. both have a single reflector

 

I should add that with the 4 bulb T5HO fixture, you will want SPS towards the top of your ranks. They will do better there.

 

sps need more light than that, youll need at least a 6 bulb fixture for the easiest of the sps

 

I made that suggestion based on the clam's natural environment. Maixmas are rock-boring clams where as squamoas like to be on the sandbed.

The clam will plant it's foot when it is comfortable. If the clam is wedged b/w two rocks, it will not fall.
