Thank you Captin Math... Thanks now I have an area to post when people say that all the time...
If your fish are not breathing heavily then, I would continue the water changes...
wow-i am so sorry for your losses! do you own your own freshwater test kit?(not the strips either). im not saying the fishstores would get odd results, but i would still test it myself everyday for a few days just to see if there are any changes anywhere..
the only other thing i can think of is bacterial, parasitic or a fungus of some kind.. im at a loss..

So I realized to today it would be easy to figure out how the surface area at any instant.
3 seconds in the water per buble (24 inches to travel)
So then in 3 seconds we have for a rena 300 pump how much air? Well rated for 200 liters per hour => 3.39 cubic inches per second => about 10 cubic inches of bubles if you are pumping a 24 inch tall tank..
So at any instant we have 10/(4/3*3.14*(1/64)^3)= about 625,000 bubbles (again rounding down)
Which means we have a total surface area at any moment = 625000*3.14*(1/64)^2= 3.3 sq ft.
So that is the lowest end... Remember if you have smaller bubbles you get more surface area, and the bubbles stay in the water longer...
Ok now thinking more on the actual problem. As stated it likely is something that got into the water, (assuming your bubbler isn't just a little thing meant for a 10 gallon tank). How well did you wash out the pumps/tops? You said they were new, so then they shouldn't have had anything in them... But who knows. With all the water changes you are doing I actually wouldn't think it would even be problems from the tank cycling (which shouldn't be happen anyways.)
It really almost sounds like poisoning though... And honestly if you had something on the glass or in the filters that were concentrated enough changing the water 50% multiple times still wouldn't be good enough.
Are they still dieing? If so I would try to set up some emergency tanks and move the fish. I would say don't use the same fitlers or anything... Then empty the tank totally, toss you filtermaterial, clean everything the best that you can, and fill it up. Then toss in some goldfish or something. (Though the problem of course is that it is the weaker fish that are having the problems I assume, so goldfish might not be a good test...)
Your situation sucks... I have been having a 55 full of young fish go bad on me too though I am fairly certain mine is being caused by bacteria, since I see signs on the fish.
Do you see red gills or are the fish breathing hard or flashing or anything?

well originally they were just dying in an instant no signs or nothing, now today i have had 3 die and i have one who seems to be dying,he cant swim well at all. So i am going to remove him now, do another water change and see what happens. Also the fish with the growth on its tail has died so I'm seriously hoping that that may have been the issue. I am at a complete loss right now. Also right now oxygen levels cannot be the problem at all. the water level has gone pretty low and so i have 2 water falls going in the tank from the aquaclear 500's plus the waterfall from the fbf , and the movement from the water shooting back into the tank. my water movement is beatiful
Stop the feedings period! What are your ammonia, nitrite and nitrate levels?
Such large water changes can do more harm than good if the issue isn't the water quality. When you added the new filters did you also add carbon? New carbon can remove O2 from the water. Once a few fish died you started with large water changes which can add a lot ammonia per water change if your tap water is treated with chloramine. Chloramine is ammonia and chlorine bonded together. Your water conditioner (don't tell me you don't use the stuff) will break the bond and neutralize the chlorine but not the ammonia. 90 gallons of water with free ammonia can be very deadly. So toxic it can kill your fish and your beneficial bacteria.
Test your water and post the results and don't use those unreliable test stripes. Get back to us as soon as you have your results.
