The reason we glue corals to the rock or plus is because the heavy current required to keep corals will blow softies all over the tank. And because hermits and snails can move them, knock them over etc.
Do you have to attach corals to live rock?

The fish will be fine. Yes they need to run all the time. I have somewhere around 3000 gallons per hour of water movement in my 40 gallon. It can be tricky to dial the directing of the flow in just right so it won't dig holes in the sand.

Good points brought up by Pete. Allowing to detritus to accumulate inside the filters will inevitably lead to an increase in nitrates. I don't see the carbon being a problem on a 90 gallon with just the aquaclear filter cartridges. I could be wrong but I think "burning" the corals like in SPS is from having higher ALK and dosing carbon.
If it were me I would toss them and add some powerheads to get that water circulating and you will have more control over the flow patterns that way as well.
Using too much granulated carbon can burn your corals up.
The use of granulated active carbon in saltwater is essentially a way to polish the water.... So use sparingly.
I agree with getting powerheads and would suggest 2 jebao rw-8. You will probably have to run them at a low speed but also have the ability to go hurricane mode if you want.

Good to know Pete! I don't run GAC in my tank but have considered it. I like to keep my set up pretty basic lol less variables that come into play and more things that could potentially go south! lol

Well gac is a good tool for removing toxins out of the water column also.
I run gac continuously in this tank. I only use a couple tablespoons.
What about if you don't have any soft corals, just LPS and sps? Also how do you run it? Media bag, reactor, or another way?
All those methods will work and so will a hang on back filter, canister filter etc. Having 4 hob isn't a bad thing but you should keep on top of cleaning the pads and run a small amount of carbon in each one. For a 90 gallon maybe around 6 tablespoons all together.
