I started my tank in June of 2015 and have done many upgrades and changes. I added apex doser three months or so after setting up. Then added 55 gallon refugium with live rock and sand bed. Over time my calc and alk was dropping. I was doing 20-30 percent water changes every two to three weeks and cleaning sand. My dose at its peak for a while went over 300 ML each daily. My sand in both tanks turned to hard cement like blocks. I have about 13 small reef fish and mixed soft LPS mostly and couple acro corals. maybe 15 total. Over the course of time up until today my corals do good for weeks months or even a year with some dying sooner. My parameters are always on target. I took off 55 gallon refugium and took out all sand in 125 gallon and replaced with new sand. I have a eshopp sump in basement RS-300 and mini 180 royal exclusive protein skimmer.i installed a new ATI 60" 4x75" LED and T5 light last winter. and I am at 80ML daily dosing now and still having issues with corals. Did not lose one fish. I have a salt water maintenance guy taking care of my tank every two weeks which we changed to three now. He seems to know what he is doing and has many other clients and pictures of tanks he takes care of. He has spoken to owner of ESV which is additive I dose daily and several other people in field. I have 2- MP 40 power heads in tank and dual over flow boxes with 4- return spouts pushing water with plenty of live rock in tank. We are at a point where we have tried so many different things that he know feels that I may have dosed too early and dumped so much into water table all these years that it could be something out of whack in water and decided to completely drain all my water and start from scratch with new water and go through new cycle. What is your opinions on this therory and plan of attack. It is getting frustrating and expensive. I have spent so much and have the best equipment apex gold controller watching everything cameras online so i can view everything alarms to trip to avoid crash no expense skipped and still cannot keep corals alive please help my fellow reefers before I throw in the towel >>
