when it comes down to it unless you have a concrete pool it matters way less.. I have only checked mine a couple times a year.. it does make a difference for CSI but you are emptying water every week..
Note MPS will show up on the DPD test unless the PoolLab has included an MPS interference remover. My understanding of MPS is the advantage is to oxidize waste before chlorine to help prevent the formation of CCs. With frequent dumping that seems unlikely to be an issue, so I'd give it a shot with cal-hypo or dichlor only first. Perhaps both, if you alternated cal-hypo with dichlor perhaps the pH rise you see with cal-hypo will be balanced by the pH reduction in dichlor?as we could have 5 guests using the hot tub and with it being a holiday let people are in “party” mode, I was considering some MPS each morning to help tidy up from the night before and take the load off the Chlorine? That way hopefully the Chlorine I’m adding will keep more consistent rather than being used up quickly to oxidise the previous evenings use? Remember I can’t ask guests to handle chemicals
I bet it’s fabric softener- this happens especially if people take a dip in their clothes cuz they forgot their suit. I had some in my tub yesterday as my son’s friend forgot his swimsuit. It was gone in a couple hours. At any rate shock level fc & filtering should take care of it. (Wash your filter out) Get u one of these to add to your tool box as well- very handyAny ideas what this is?
fresh fill yesterday so can’t be anything too bad. I’m thinking either ash from the burner or just soap scum? It wasn’t immediately visible but came up after having the bubbles on for a while.
very difficult to get rid of. Had to wrap our skimmer net in a pair of tights!
Also we had a family of 5 in. Overnight FCl dropped to 0.5. It’s taken me 40g DiChlor to get the reading up to 5.0.
Is this where MPS would be useful first to burn off the organic matter first, then add (less) DiChlor after?
The advantage of MPS would be less CC generation and lack of CYA buildup. With your weekly water changes it’s unlikely to be a big issue either way, but yes, lots of waste after a heavy use is exactly the situation where MPS can be useful.Nice one, I’ve found a net with a really fine mesh so will see how that works.
if it takes 40g of DiChlor to get the FCl back to 5ppm is that the best route or use non-chlorine shock first?
