Welcome to our forum.
The results are the opposite of what we expected. Why does one tub clean up so much faster then the other?Any ideas? John
Try the same experiment with water already at desired temp. The only reason you got the extra filtration in the coleman is because it was heating water.So if you are saying that no circ pump will clean the water faster at start up, I agree. What about the rest of the year?I would love to see the experiment done with a tub with a "real" circ pump (35 gpm). A Sundance for instance!

no way of knowing how clean the filters were to start with.
By the way: does your water run cleaner after it has been running awhile?
lol....wow its good to look at the diffrences... that real circ pump on the Sundance are they also still running the larger pumps during the day in addition to that real pump and if so WHY? that is is something that is newer right? I understand that it will not be around long as with the current system there is no chance of it passing the energy standards that are going to be required here in the very near future.
The high flow circ pumps on the upper end Sundance spas do all the filtering. The main pumps are for therapy only. This differs from the older style Sundance system that used a low flow circ pump with the two speed therapy pump number one that also filtered.
So you're saying that the jet pumps don't come on at all during filtration... not even when the spa defaults back to factory programing?
