Jonas 3 lb Winter BorateTab Cartridge
The larger charge, for the larger pool.
The Jonas 3 lb winter BorateTab cartridge, part NJP0100201 and stocked under SKU PST-NJP0100201, is the larger of the two borate cartridges, sized for pools that need more buffering capacity to get through a closed season. It floats in the collar and releases borates slowly, holding pH steady while the pool sits with no pump, no test kit, and no one looking at it. That steadiness is what keeps the rest of your closing chemistry doing its job. The floating collar, part NJP10030, is required and is sold separately.

How is this different from the 1-1/2 lb cartridge?
The 3 lb cartridge carries twice the borate charge of the 1-1/2 lb cartridge.
Can I run two cartridges at once?
Each cartridge requires the floating collar, part NJP10030.
Do borates replace algaecide?
No. Borates buffer pH, but a closing still needs a dedicated polyquat winter algaecide to actually hold algae back.

Let customers speak for us
No issues with it. I received great customer service ensuring I chose the right thing and shipping was really fast.
Can not say enough about the Balboa retro fit system. I’m no expert, but I watched a you tube video and installed it myself. Hot tub is 14 years old and is up and running like new. Very pleased with my purchase. Thank you.
The process was smooth and lights arived as expected. Everything test out in good working order.
Needed to replace the control overlay on our Nordic Impulse hot tub, but could not find out the make or model number of the actual control panel on our tub. By taking measurements and photos or our actual control panel button positions and functions, I was able to narrow down the options. I ordered this overlay as the button positions seemed to be in the right positions, even though the overall size was smaller than the control panel. The overlay works, in that all buttons and functions are in the right place, and the overlay seems to have adhered well to the panel. It is not a perfect match, as it is smaller overall than it should be. But I am happy with the result and will buy an additional identical overlay as a backup in case this one, too, deteriorates at some point. Took a lot of detecting, but the result is successful!
This costume is legit. It has the sparkle, glittery sheen to it like the one used on screen! Very happy with it!!
Excellent service!
PST was great at communicating the status of my order throughout the various stages. I actually did encounter a shipment issue and they handled it without issue. I will be doing business again with them.

as described, fast shipping
My wife has RA and is always uncomfortable. Our hot tub heater failed and all the local shops were not able to assist until November. I was able to order an exact replacement part which was delivered within 3 days the hot tub was up and functioning in three days. I was very impressed with the quality and service.
Good quality just ordered wrong size and also need thicker cover
Fit perfectly, and fast shipping
Super fast shipping and reliable product !
I accidentally broke the original knob by tightening it too much. This was a perfect fit and works 100%. Fast delivery too!
Swapped out broken heater (lasted about 6 years) for this one. The instructions are for the electronics, not for the plumbing. You must get everything perfectly aligned or the plumbing may leak. I needed to loosen the electronics box to get the plumbing perfectly aligned. I have hot water again.
