External filtration systems

[jerzy]

I've been dumping and scrubbing way too often. Doing all the right stuff. Looking over the internet, can't find anything like this. Anyone have any suggestions?

 Not sure what you are talking about. An external filter unit will not help, either way the filters need cleaned and chemistry needs balanced with shocking as needed depending on the amount of usage. Normally an average residential hot tub should only need to be drained 3 to 4 times a year.

If you handle your suits right, and make sure to go in after your shower. Then be sure to sanitize/shock properly based on use. Going every 3-4 months on a fill is very common.

With the cost of the system, plus external plumbing and loss of pump head I'm not sure it's worth it.

In my 30+ years in this business, I have never heard of such a thing. The only thing this would do is allow you to go longer between filter cleanings. The "stuff" in your water that's making it so "crappy", is far too small to be filtered out with this type of filter. Me thinks you just need to learn how to more properly care for your spa.

Why not start with explaining what exactly your problems are, and telling EXACTLY what you're doing to maintain the water (including all the chemicals, the amounts you're putting in, and test readings).

 I think it would be a waste of money and if you are in an area that freezes it could also be a very bad idea(loss of efficiency, possible freeze damage to external unit). I clean all my service tubs filters every single week and that is regardless of the sq. ft. of the cartridge. Cleanliness entering the tub and shocking are the two key factors in hot tub health.
