    Multiple DE filter panels found with holes during cleaning

    Yesterday, I did the spring cleaning of my DE filter. Most of the time I do it, I seem to find one panel that needs replacement. Normally that has been because the fitting that connects to the water supply manifold was broken/cracked. I was surprised yesterday that four of the panels had a...

    Expected life span of a DE filter o ring

    I cleaned my Pentair FNS+60 DE filter a few weeks ago and it has developed a leak under the belt clamp. I generously lubed the o-ring and have tightened the clamp so that the springs touch and even a turn or two beyond that. I believe the filter assembly was installed with the pool 20+ years...

    DE filter clamp not releasing

    I set out to do my annual spring filter teardown today, which I've done a few times before, but I couldn't get the belt to release. The nut/spring came off like usual, but the tension stayed on the belt since I can't get the T-bolt threads to slide out. Any suggestions?

    SWG scaling analysis

    I've noticed what I think is scaling starting to accumulate in my SWG (please let me know if it's not scaling :) ). I've attached a couple of photos. Does this seem like a little, a lot, or in between? My TA has drifted up over the last few months, so I'm starting to work on bringing it back...

    Help me find another one of these

    This came with a little water feature I bought for the pool, and it regulates how much water flows from the pump to the water feature. I'd like to find another to use elsewhere, but can't come up with a good name / description. Does anyone know where I could find something similar and what...

    My SWG installation saga

    We bought a house that had a pool 4 years ago, and have been managing it ourselves ever since. We've been thinking about adding a SWG for the last year or so and this spring as the chlorine demand started to rise, we decided it was time to make it happen. My initial plan was to hire someone...

    Skimmer weir door stuck full open

    I looked at our skimmer (the lid is a Waterway 519-6450), and it appears that the weir door is present, but stuck open either by adhesive or by the tile grout. I've included a couple of photos, one looking out toward the pool and one looking in. Any suggestions? It would be nice to remove it...

    Dried glue causing valve to have a small leak

    I finally made the time to re-plumb my pool/spa return so that I could shut off the spa spillover and control it with automation. That all went ok (I might post some pix and lessons learned another time). But, once the install was complete, the spa would still have a tiny trickle spilling...

    Standard fitting for acid pump

    I'm going to be installing a SWG in the next month or so, and have considered adding an acid pump at the same time. I've decided to wait and see my acid demand after the SWG is running. Is there a standard plumbing fitting I could include when I do the SWG install to prepare for a possible...

    add a shutoff valve

    To reduce aeration, I'm working on getting my pool setup to allow automated control of spa spillover. I changed the wiring in my automation panel today and flipped the dip switch to enable spillover control and that went well and works like it should. I attached a photo of how the plumbing is...

    Choosing SWG

    I have a Pentair VS filter pump and Jandy Aqualink RS-6 automation (more details in sig). Based on my reading in other threads, the Circupool RJ60+ seems like the best SWG, but is there a SWG that would be more compatible with my setup?

    Threaded vs glued connections

    I'm starting to plan my SWCG installation. I was originally going to hire a company to do it, but I haven't had any luck finding one interested. So, I feel like it would be better to just do it myself. As part of the process I want to re-plumb the spa return, so that I can manually shut-off...

    Another spillover control question

    Pepperdinegal's thread in this forum about spillover got me motivated to figure out how to control spillover in my situation, which I've been meaning to do for awhile. I've attached photos showing my return plumbing. One pipe that descends into the concrete goes to the spa, and the other goes...

    discoloration

    Can anyone help me ID the discoloration in the attached photo? The stained area is a step in the pool and has that golden brown color; my shadow is also visible which creates an area that appears darker. We had a few spots that turned out to be iron, because vitamin C took care of them...

    Volume of a drop of R-0871

    I'm working my way through a SLAM; my CYA is 60, so I'm using a lot of R-0871 drops to do the FC tests. I came across a thread the other day saying that I shouldn't squeeze the bottle when dispensing drops. I think I was doing that too much to hurry the process, so my FC readings were...

    When to increase CH and a question about adding MA

    I think my test results are visible, please let me know if they're not. I did a pool water exchange a few weeks ago to reduce CYA and my CH dropped from 450 to 275. 275 is just above the minimum but outside the recommended range. Would you recommend that I increase CH to 350, or leave it as...

    small patches of green algae in shady parts of pool

    Hello - I tried searching through the forum and didn't find my exact issue addressed in the past. In the last few months, small patches of green algae have been forming off and on. It brushes off easily and I have never observed it grow in the parts of the pool that get direct sunlight. The...
