Hi there,
I bought 2 overflow boxes online. The seller doesn't know the the type of these overflow boxes. Any one could help me ID them and tell me how many gallon per hour they will be?
Thanks in advance.
The first one has 1'' hole.
The one below has 1-1/8'' hole.
The second one is a cpr overflow, I have the same one on my 40g system, it's a nice overflow. Check thier site they make a couple different ones, with different flow rates. Good luck.
I believe the brand of the first on is Pro Clear made by a small company in FL and is part of a wet dry system, I have the same one that now flows into my sump had to call them to find out the gph rate and I believe it was 475 gph.
