I hate to say, but the first step should be trading the softies for the lps, because the two don't get along without problems. Softies spit chemicals designed to clear their areas, and it results in unhappy lps and sps.
If you wish to try, I'd suggest running carbon to remove those chemicals, and to position the lps upcurrent of the softies...BUT: bubble and tentacled lps will sting their neighbors to move THEM out, so be sure to allow 6" for the longest-tentacled lps.
Short tentacled, hardy: caulestra [candy cane].
Medium: frog and hammer [can touch each other], maze brain.
Long: bubble [a shade stony], galaxea [6-8"]
Mobile: plate coral [expert only]
All but bubble like moderate to bright light.
You might

consider leaving your successful AC24 for softies and setting up a separate system for the stonies---that's how you blow the rest of the funds the first tank didn't get.
On the other hand, you could investigate some of the more exotic softies, which do get along [not because they're friendly, but because they have defenses against chemical spitting.]
