hi ppl as you will see im new to keeping fish,i bought a jewel190 corner tank and i have 2 eheim classic filter pumps the problem is they were working fine untill i decide to clean them .the prob is they work for about 3 days as normal then the water slows right down and the tank goes all misty as if i have a blockage but dont think its that .just water intake has slowed down so much any help would be great .
cheers ppl ron
