Just some updates, Jebao doser was setup, then died 3 months later, its getting warranty replaced, but since it happened right before going on vacation I broke down and got a DOS. Over the next 2-3 weeks I think I have it dialed in, dosing 120ml of 2 part over 24 hours equally spaced 15 minutes apart. I was testing alk at 7am, and 7pm, and it was withing .3 of each other. Starting to see some corals coming back, other definitely have died. I'm really hesitant to add new corals but there's been alot of new sales recently. Also added a RO buddy smart pump, increased water production by probably 2-3x time, and its capable of putting out 0 tds water now still with no DI resin. Added some float valves to the mixing station. Fixed some apex programming issues, and Harry Singer 3d printed me a snail guard for my display tank float switch. Also ran my prime line into the sump, so with the added gravity siphon it actually runs really well now, along with being silent, I think it will also add the to the life of the pump. Pics will hopefully follow when I have time.
