Just curious if the experts in this TFP community think paver joints are a higher risk for seeding algae in pools. We have a screen enclosed pool with a paver deck. Some of the joints are a bit black (with moss?) even though sealer was used and I hit them with bleach from time to time. I’ve managed this year old pool with the TFP algorithm and its been great although I am now suspecting some rising chlorine usage even as the weather moderated. I have had to dial up my SWG % to get the same levels even though the water looks fine so far and no CC. Doing OCLTs in case and for now keeping FC higher in range. This seems to have possibly started after the last big rain we had a while back. The deck drains and drys well but I would guess that the biological stuff from paver joints could find a way in on feet or by splashing. So if indeed I have to SLAM I’m still wondering about the source and possible high inoculum potential from paver sand joints and about disinfecting the Crud out of that too. I like pavers but is this a consideration in choosing pool decks vs concrete etc.?
