I am using a Color Q photometric test kit by LaMotte. Which aside from a couple of issues, I love.
My problem is that no matter what I seem to do I cannot get my free and total chlorine numbers in line.
They are always consistently more than .20 apart, which because I have a semi public pool concerns me.
I don't think it is the test because I have used my DPD tests and get very similar results. I've also had my water tested at a pool place.
And just to prove a little knowledge is a dangerous thing, I just took my first level pool operator course and I now feel more confused than ever.
My question is how do I go about getting these numbers closer together?
I have to submit water samples once a week to the health department and have already got two unsatisfactory results, something I don't want to repeat.
I have a 100,000 litre vinyl in ground pool. We have no less than 10 to 30 people in the pool at all times on the weekend and very little bather load during the week. (We are a campground)
Free Chl 2.00
Total Chl 2.71
Cyn Acid 100 (yes, I know it's high, that was one problem with the Color Q, inaccurate for Cyn acid, so I added)
I use Trichlor pucks in our Hayward feeder and calcium hypo for shock. I also have been using Pool Perfect.
I notice that my pool gets very cloudy by Saturday night and then takes a couple of days to clear. Is there any way to avoid that? I know it's the heavy bather load and all the various things they put in the water but there must be a way to keep it clearer.
We are installing sensor and auto feeds for Chlorine and Ph soon but in the mean time I'd like to get on top of this.
Thanks in advance
