Love all the corals! It’s sad your sticking to just one type of acropora. I also love seeing collectors interact on boards like this. Don’t take the following the wrong way I am just trying to help by giving some experience and am curious what you think. Considering your losses are so high with the coral your selling and collecting I would second the notion of trying some halide lamps like Texas Todd was talking about. You should be able to lower your prices by getting more corals to live. I don’t think tiny swings have anything to do with new corals dying either, unless the coral was on its way out to start and from my experience half the corals from wholesalers I have got died within 2 months. I love how many fixtures your using and I bet you would be astonished at how well a halide can color up a coral to look amazing under blue light and at this point you might even save money on electricity.
Also buying straight from the point of origin is easier on the coral ime. Buying from wholesalers is just buying pieces that have been handled many times over and allowed to sit with a lot of other corals and in the end I have seen more deaths (from stress and handling) when trying to order from a wholesaler than if I order straight from indo and setup the correct tank to keep them alive. Most people collecting wild corals to grow and or resell have much better survival rates. They also get to sell the corals that are not worth propagating before they turn an odd color or die.
