i run a wet dry and supposedly that should be a great way to aireate the water. is it? i have a sick ray and i finally turned on a bubble strip and 2 powerheads with airlines. he's a tad more active. how much aireation is needed? can too much be bad? i have a 100 gal, with 2 good size retics (9" and 7 1/2") yepezi 4". 18 " longnose, 15" lima.
