reef lighting

I am new to this. I am interested in ensuring the correct lighting for my corals. I think what I have is wrong. When I read on lighting, I struggle with the complexity. I would like to tell you about my tank and what I have and if you would be so kind as to advise on anything you read, I would be grateful.
Tank = 90 gallons. This 90 gallon tank has been fishless and cycling for a month.
fish = 5 ocellaris clowns and one goby (the clowns are tank bred and raised together and so far get along fine) These have been in the tank for 2 days.
LR = lots and lots of it (sorry, didn't measure)
filtration = two marineland canister filters, one 50 gallon and one 100 gallon. Protein skimmer died and I am saving for an octopus over the back as advised by this forum.
Corals = top of tank: blue anthelia (doing well because I feed it daily), various zoos and palys as well as some interesting russet colored mushrooms (all doing relatively well).
Middle of tank = More zoos (doing relatively well but some do not open very often), a new red flame blastomussa colony (not as bright as when it came in but seems ok), a superman montipora (crossing my fingers here but seems not to have changed..its not as bright and amazing as I thought it would be but seems not stressed), and two rhodactis mushrooms (placed into the shaded areas but still look totally miserable folded over onto themselves).
ricordia mushrooms seem to have lost some of their color but are multiplying.
bottom of tank = purple and green mushrooms (seem happy), a few zoos doing well, and a wellsophellia brain (sometimes looks good, sometimes looks bruised. Just when I think I should never had added something so complicated, it perks up)
Lights = new light that came with new tank when I switched from the 55 gallon ...coralife 50/50 48' long t8 32 watt
Two 18 inch lights = 1. coralife 15 watt 10,000 k
2. coral sun 420 actinic 15 watt
and finally two 12 inch LED strips purchased by my pet shop man (box had no details) appear to be "stunner lights" at 6 watts each. These did not come mounted and get VERY hot so I have them resting on small rocks to keep them from the glass top of the tank.
Water parameters = 0 ammonia
PH 8.0 (i have been dosing using the proper PH 8.2 for the last three days but am tired of adding chemicals into my tank. My pet shop owner says continue to add the purple up daily and it will adjust itself).
nitrites 0
salinity 1.026
These are the only things I have been advised to test for.
Thank you in advance for your thoughts

oops, add one large powerhead, one medium one, and one small. The small is aimed at the anthelia and the others are in the top portion of the tank and aimed at the front. The only corals that I have that appear to need strong direct flow is the anthelia.

i ran my 90 with two 175 watt mh's for over 10 years.actually still running but i donated the tank to my wife for her turtles.i kept alot of corals in that tank.actually they out grew the tank so i bought a 150 and now have a 250 .soon to be a 490. i am a big metal halide person but i recently had a customer of my business that has a 90 with a t5 set up with alot of corals. so with the new technology out there you can go a couple different ways. looking at that guys corals and thinking t5 is a nice set up and the bulbs last longer

From what I read, I don't believe you have enough light for corals. I know you have a lot of lights, but not the intensity that you need. Stunner lights don't provide enough light period.
Metal halides, quality T5 units, expensive and quality LED units, and a mix of t5 and VHO are usually what people go with these days. You could also mix quality LED units with T5s, or mix metal halides with VHO or T5's. There's no real watts per gallon rule anymore.....
I had 8 T5's over the top of a 90 tall (32") and was able to keep a clam on the bottom. So,... that's pretty good.
I've also used metal halides in the past and have been able to keep anything under the sun - literally. Just depends on what you are going to keep.

How about the aqua life system that includes 4 t5 lights?
Would that be sufficient for my tank?

Personally, with your open brain and montipora and a couple of other corals you have, I would suggest no less than a 6 bulb unit, preferably eight. That way you can keep anything you want. Not only will you have to buy the fixture, but you should also replace the bulbs with more energy efficient, better quality, higher par light bulbs - I like ATI brand myself.
A four foot 90g tank would greatly benefit from a retrofitted metal halide system with a couple of t5 supplements too.
It seems like you are going for a nice mixed reef, so you want to have just enough light to meet the needs of its most demanding corals.

I wanted to get back to you to say thanks.
I appreciate the advisement. I purchased T5 lighting (6 bulbs) and will add more as needed.

Your welcome! I'm glad you took the advice. You will not be disappointed!
Please start a build thread if you don't have one already - we would all love to see your tanks progress!
