Help me get my tank back on track, please!

Keep it simple. You shouldn't really be adding more equipment unless its a GFO reactor. At least not yet.

Get good test kits.
Baking soda for low ALK, limewater for dosing and keeping everything in check.

Cyano needs the GFO. It will keep coming back, lighting isn't the problem.

Don't dose if you can't test- calcium reactor, ahem...

Vinegar bath the skimmer if needed.

A 6x54w T5 setup is proper for a 75g. You are gonna need it for SPS. Don't buy any lights without lots of research and asking about it here.
As for the look you want General Electric makes the GE6500 and its a great bulb at the best price of any of the good T5 bulbs we use. GIESEMANN "midday" is also a true daylight bulb.

I think a ge6500 and ATI blue plus together make a very pure white look.
Maybe 2 ge6500 & 2 blue plus is a good color temp that you will like. If you want a hint of yellow use a coral plus or maybe an aquablue special instead of one of the blue plus.

Stick with it, it can only get better if you try to fix it.
