Finally my tank together and the floor was dry this morning!!!! :bounce: 135 gal ,wood canopy with 2x96 & 2x55 ah lights, Flourite, substrate heating cables,,, (witch I think are going to a real pain down the road,) and for filtering a xp3 and a 2028.
I barely hear mine from about 5 feet away under a cabinet, so they are very quiet. They have a pretty good flow rate too so it cleans my 55 very well. The sound it probably closely compared to the 2028 since it's the same company and they are probably using near similar parts.
