CPR CS100 Overflow Box

[Crimthann]

Anyone try to use one of these? I need some more flow on my 75 gal and I was curious to see if anyone has tried using one of these with a Aquatics Aqua Lifter dosing pump connected to it.

Personally I would go with an U-tube overflow box -- I use the LifeReef one on my 75. I think the CPR one (( and any C type )) is a poor design.

yes hes right. they looks good and pricing but poor design, i have one overtime aqualifter wont help much. dont know why but suction will get weaker and weaker and tank will be flooded. +this is my second aqualifter out of 8months. i will go for lifereef

Yes, I tried to use one. It failed twice in 3 months. Do yourself a favor and get a decent U Tube overflow.

I have the CPR 100. Go with something else. I am frustrated that in some ways I am risking my entire system to the reliability of a 10 dollar pump. They fail eventually, I'm on my second one. If you change the bladder inside periodically, or buy new ones, go for it. It hasn't failed on me completely, but I have had a few close calls.
