Fouling Fish tank Problems?

so I'm getting a 37 gallon + fish tank tommorow because my fish tank is becoming poluted, and slowly poisoning my fish.(i had to put them in a 10 gallon cuz my other fish tank cracked...i have 1 angel, 1 bolivian ram, 1 african featherfin catfish, african brown knife fish and a bristle nose pleco) i need to put them in the tank quickly cuz idk how much longer they can survive in there. so is there anyway for me to put the fish in the newly bought fish tank right away? the old tank is a 10 gallon fish tank with 2 filters a 10 gallon filter and a 25 gallon filter. can i thuroughly clean out the filter and use that in the new fish tank along with the new filter? because lately the fish tank is fouling up even with water changes, and with all those filters and causing alot of funky smells to come up. can i just use the 25 gallon filter on the 37 gallon tank with the new filter to get the cycle going and the fish established?
