Product Questions

Hi, what is the size of the outlet for the water escaping the skimmer? I want to attach pvc to it in order to feed a 2nd sump with return pumps. I want the skimmed water to go to another sump and need to know what size pvc it is.

trying to decide between this skimmer and the 202s in a 90 gallon with a medium load. any thoughts
Question by: Tom Lowers on May 23, 2017, 8:35 AM
If you have the room for it, I would personally go for the 200INT. The space saving skimmers are always a bit of a compromise on performance in order to save space, and as long as that's not a limiting factor, you'll find it's easier to maintain the skimmer pump and you get more ideal performance from the classic skimmers with externally mounted pumps.

Hope this helps!

Hello, what is the minimum sump size to properly house this skimmer?
Question by: Walter Maldonado on Nov 28, 2016, 5:46 AM
Great question! The foot print of this skimmer is 14.6" x 9.8?. So you will need a sump large enough to accommodate that footprint. :-)

What are the differences between this model and the classic 202-s model?
Question by: Mark osborne on Mar 12, 2016, 2:10 PM
Great question!
The difference will come down to foot print size. Both will be designed for 250-150 gallon systems. The 202-s has an internal pump while the 200int has an pump outside of the skimmer body. Feel free to let us know if you have any further questions!

energy consumption?
Question by: mark on Dec 10, 2013, 10:57 PM
Hi Mark,
The manufacturer's information says 41watts on the included pump.

Hi, do these skimmers come with a wedge pipe or gate valve for adjustment? I see a gate valve in the picture here but I have seen pictures and reviews elsewhere showing a wedge pipe...
Question by: Ken on Sep 2, 2013, 6:56 AM
Hi Ken,
They come with a gate valve. They used to come with a wedge pipe years ago but have been gate valves for quiet some time now.
