Correcting RO/DI rookie mistake

[bigterp77]

So I made a dumb rookie mistake and my RO/DI unit wasnt set up correctly (real embarassing... my RO unit was in backwards). Assuming the DI unit was picking up for a lot of the slack in the beginning but I have some high phosphates (.80). I fixed the RO/DI unit and figured to do a bunch of water changes through the next few weeks to get it down so it doesnt crash. Fish are fine but I obviously have gotten little to no coral growth and browning due to the dirty water, they are obviously struggling. I dont have any algae issues so I thought that tank was fine.
I was going to begin running GFO to help get the phosphates down, but should I be looking at doing anything else? Nitrates are high around 10, should i be looking at using biopellets or just use carbon in the tank to help get the numbers in the tank down? Im assuming if i lower the phosphates without addressing the nitrates that could present a host of other issues. Should I just rely on the waterchanges to get the Phosphates and Nitrates down slowly?
What else should I be concerned about while using well water?

Thanks for your help!!!

Nitrates of 10 isn't really a high level. Just stick with your water changes and you'll gradually improve your water quality. You can run GFO or a temporary phosphate remover.

Water changes to slowly fix the phosphate are probably best and safest. The nitrates are fine.

As stated, the nitrates are within acceptable range. WC's and GFO to reduce phosphates. I would also be running carbon at this point, as anything could have been introduced to your water column from unfiltered well water.
