Looking for CPR CS-xx Deluxe Overflow Box Experiences

[FBNitro]

Anyone have any experience with these overflow boxes? Anyone ever had one lose suction on them? The pump 'should' eliminate that chance, in theory.

yes i have had the dx-150 running on 2 of my tanks.... the problem i came accross was that in a power outage the air lifter couldnt pull the air out of the siphon fast enough to start a full siphon again and poof 15- 20 gallons on the floor..... i liked my u-tubes better.... only problem i had with them was i had to keep them clean cuz i was pushing max flow threw tham, and if i waited too long to clean them then the flow slowed, and it would slowly raise the level of my tank till finally it overflowed.....
