SOS my ammonia and nitrite !!

[09jk]

In my 90gal freshwater with a 36gal sump. Daily changes , accu, conditioners. My levels are still high and my fish are gasping for air! Been set up over a month now.
Ghost knife, peacock bass, pleco, Oscar. All are juveniles.

I'm stumped, this is my first time running a sump.

I'd like to pay someone to come by and see what I'm doing wrong.
I've spend lots of money on my set up and nothing is working out right.
I'm almost at the point were I want to get ride of it all, and start with a larger tank and a couple canister filters. I'm into the tank and sump now close to a grand now and I'm having nothing but horrible results

I'm in the nw part of Edmonton 134 and 124

Give me with a number if ur available
Thanks Curtis
