my RO unit was serviced not to long ago, i believe back in December, i also have a TDS meter on it, it reads 0 for the RODI water coming out

any other thoughts??? things are still dying off and i have no clue as to why??

Not sure why yet,

But do a few big water changes and try running some carbon for a little bit even if its in the filter socks maybe a contaminate got into the tank

WC and carbon are a good start for most problems then keep diagnosing it

Fish all look ok?

Well bud, it's not easy , could be hundreds of guesses, if you say all you parameter are good, maybe something is in the main water in your house, light intensity, something got in the water accidentally, try to get the store or a friend to test the water for you, just to make sure it's all in check...
If corals are dying, something is not right...
Did you start using some new product?

You said you had neglected your tank, how did you arrived at 0 Nitrate and 0 Phosphate? Maybe you stripped your tank nutrient so fast.

what i mean by neglect is, i havent had as much time as i once had, im not testing things as much and im not changing the filter socks every three days, i left them in for weeks....
anyways i did a water change and i added carbon...fingers crossed
