I'll agree, to keep the peace. But don't go overborard, I don't care what Seachem may say about doubling or tripling the dose...chemical is chemical and it adds stress to fish at the best of times, and even more when they are already weakened.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

Another one of my favorite angelfish have passed away. I am in the process of checking my sink water. Again none of the other fish seem to be bothered by anything..

pH is still at 7.6
Ammonia is at 0ppm
Nitrite is at .25ppm
Nitrate is at 40ppm maybe even 80ppm.

I did a water change about an hour ago, 50% and added two capfuls of prime. The other angelfish are doing worse than yesterday.

Are you using buckets or a direct in/out-flow water change system? If it's the former, treat per bucket volume each time, if it's the latter you would treat for the total tank volume. Given the situation and the concern about added stress by over-dosing (even though it's advised as safe by the product info) I would be tempted to go with buckets so that you can direct treat the water and not have to add any more chemical than absolutely necessary.

I am using a direct in and out flow water change system.

Here are the water parameters from the faucet

pH - 7.6
Ammonia - 0 ppm
Nitrite - Very High - cant tell if either 2ppm-5ppm
Nitrate - 5ppm

I can't believe the readings for my faucet water...

This can be handled by using Prime for a conditioner or any conditioner that detoxifies these. There are several Prime is just one. Do you have any live plants?? These will help also. As for when to put the conditioner in I would still put it into the tank first then turn the water on and fill the tank.

I do not have any live plants in my tank. I syphoned out half the water then before filling it back up, I put in the Prime (enough for the whole 90 gallon, not just the new water)

Floating plants will help ad in the removal in nitrates in the water.
Also Abbeysdad has written a thread on how to handle this issue. You should read it as I think it will help you out. http://www.tropicalfishkeeping.com/f...-water-156489/

Also I think you adding the amount of conditioner to cover the tank was a good idea at the moment but you may need to do more down the road (and I am not talking about adding more conditioner.) and that thread from Abbeysdad will explain and help more then I can at this point as I don't have nitrites or nitrates in my source water.

What kind of plants should I add? I am not too knowledgeable about planted tanks. I have a Marineland LED lighting system. It is 1800 lumens
