Factory installed filter restrictor in Master Spa? (with video)

[BB_Mike]

I believe this is a common sense question that is not brand specific, but I'd like some experienced input from you all.

I just purchased a 2015 Master Spa Twilight 67.25.  It has two filters.  One normal and one with an Eco Pur insert (so a special filter inside of a normal filter).  For the hole that the eco pur filter screws into, there is a green plug/restrictor.  It has three tiny holes in it that are 1/8" diameter.  It cannot be flowing much if any water.

Here is a video of it:  https://www.youtube.com/watch?v=cTui6vWEcy4

I think this was a factory installed piece to keep debris out of the return before a filter is installed.  Only it never got removed at the dealer or at the delivery  What do you think?

Also, the previous owner used Bromine while the user manual states in bold to not use Bromine with the Eco Pure filter.  I intend to use bromine, so I think my next step is ditch this two part filter (on the left in the video) and just simply run two of the one piece filters.  Make since?

The disk looks like it's a broken off piece of a bromine floater.  Absolutely remove it and yes, you'll also want to ditch the Eco Pur two stage filter and just use the same type single stage filter the other side uses.  The Eco Pur filters clog quickly, starve the circuit pump, and are expensive.  For these circ pump/low flow applications I recommend Pleatco brand filters as their open core design allows more water flow even as the filter media clogs over time.

Good luck,
