Ozonator Connected Ok? Spa Sanitation Issues...

[mgrobins]

Hi,

been a while since I visited the forum .

I have a Jacuzzi of 3100L I think. When I first set it up about a year and a half ago it was workign well with the N2 carttridge and ozonator functioning (well it was bubbling air in at any rate).

The one-way valve for the ozonator failed and it ingested water. I replaced the ozonator but note that it has 2 connection spots for the hose to the water-line. My question is, for a CD type ozonator is the line I connect to irrelevant? There are no markings to suggest which I should have as input or output. I figured the chamber produces ozone and the venturi effect of the water would draw it down whichever connection I have the hose on.

The reason I now query this is that I am finding that with a N2 and ozonator I get cloudy water and a strong drop in pH after a few days away for work. How much of this should the ozonator be stopping?

The only other change to the spa has been a pipe I blocked to a 'waterfall' feature that was leaking internally. With no corculation through this pipe I figured it may have formed a biofilm and be seeding the spa with bacteria. I'm going to fix the leak or at least get this pipe back into circulation.

Overall I'm after any suggestions people may have

Cheers,

Well, I pulled apart the waterfalls on my J-385 (actually 2100L not 3100) and resealed the leaking fittings. There was a fair amount of bioburden in them. After fitting the hoses again and running it while I shock the spa it's looking a lot nicer.

Time will tell how much of an issue it was but I do think the blocked hose was allowing water to stagnate and affecting my CD.

Still keen to know how much effect the ozonator and N2 should be having...

are you using anything with the ozone and nature 2, you should be using chlorine or MPS with chlorine as needed.

I use bleach and shock with MPS as needed .

My queries are more about how much of a difference do the N2 and ozone make. Both cost money and are sold as items that enhance or replace the need for chemicals but a sanitiser is still required.
