Well, it has been awhile since I have posted. My boys and I rebuild our entire pool system a few years ago and I wrote all my own software to manage and maintain it. We converted to SWG and never looked back. Now years down the road I have hit my first problem. In the last five years we have done nothing but add acid to our acid pump and occasionally add salt.
Well, a couple of weekends ago my wife and I took our kids on a little vacation and while we were gone my pool panel circuit breaker tripped for some reason (never happened before). As a result my pump shut down as did my SWG.
My ORP crashed and FC tested at 0 when I returned. With a water temp averaging 90 degrees. when I got home we have a little bit al algae showing up. Of course, being a longtime member here I knew I needed to SLAM the pool.
So, its been awhile (5 years) so I downloaded the app, put everything in and it says the recommended SLAM is 1 to 3 which I find very very low. Then when I look at the chart for SWG pools for SLAM (my CYA measured ZERO) it is showing 24 FC at 60 CYA but the chart does not go below 60 CYA, I am at Zero. For non SWG it shows a 10 FC. I am not sure why SWG pool sneed a much higher FC for SLAM as opposed to traditional pools.
I took the middle road and selected a SLAM Target FC of 10, but that really does not seem to be doing much after three days so I am wondering if I really need to double that amount per the calculator.
Before SLAMing I dropped my pH down to 7.2, it generally runs about 7.5.
I don't have a problem jumping up to an FC of 24, I just wanted to sanity check my numbers before doing so. In the app, when I put in a SLAM target of 24 it tells me in red that it is outside the recommended range, FWIW.
Any thought would be greatly appreciated. I have been totally babied these last five years with our system literally running itself with zero algae or problems. I add acid when my system tells me its low, I backflush the filter when my system tells me to, I run the vac and empty the strainers. Now I have algae and I want it gone
Of course, the other issue is that I am in Phoenix with 119 degree days the last few days so holding a SLAM FC level in that heat and sun is brutal.
