How do you like the prime? Was actually looking at that and the Kessel A80 since its only zoas and SoftiesI have a tank similar dimensions to yours, with yours being slightly wider and taller, and I don't think the A29 would be the best choice here. I had it on mine for a few months and switched to an AI prime and there was a HUGE difference (I'm actually working on getting a second AI prime to get rid of shadowing). If you actually want to keep an SPS dominant tank, id recommend getting a good light like a radion XR15 or XR30
