    SLAMming for almost 2 weeks

    Make sure you add the DE extremely slowly. A little at a time. I added to quickly and the pressure rose 25% within a few hours - I backwashed etc. realized that I was really just backwashing mostly the DE.

    The Pool that wouldn’t clear...

    Yes. For 3 weeks straight I had stable FC. I had SWG off for initial 3 weeks and passed OCLT for 2 weeks straight with SWG turned off. For last 1.5 weeks have had SWG on and everything was stable. Last night had to add the LC to get to shock level. Today adding just a touch of DE and letting...

    The Pool that wouldn’t clear...

    12 hours later, I was close to 25% psi rise so I went ahead and backwashed. Previously to doing the DE drill, I’d reach 25% in 2-3 hours. I think I know what happened. I think originally when doing the DE exercise, I was putting to much DE in - and although I waited the 2 min to stabilize each...

    The Pool that wouldn’t clear...

    Thanks. I’ll look into it. Well, I can’t explain it, but I just checked pool and cleaned leaves etc. Pool has never looked more clear - in all my efforts this past 30-40 days. Overcast day here FC is still 22-23. PH has climbed a bit to 7.6/7.7, though FC is above 10 so this can’t be taken...

    The Pool that wouldn’t clear...

    This morning: The good news is the pool looks almost like it did prior to all these leaves. FC is 22.5. So no drop overnight from the 3 gallons I put in. I really have no idea... Put the robot in and added some DE..

    The Pool that wouldn’t clear...

    Just checked FC. It’s down to 5. It was 9-10 about 7 hours ago. Something is going on as it has been very stable FC wise last 3 weeks. The only change that I know of is the leaves falling. I lowered PH to 7.2 and brought back up to SLAM level for overnight.

    Robot has been in daily. I’m using the smaller filters it Came with. I don’t get much. Standard very small debri.

    It’s a 500 lb sand filter. Returns are pointed toward the surface.

    The Pool that wouldn’t clear...

    I generally would have no problem turning the filter off but as my birch tree keeps shedding leaves m (skimmer baskets getting a bit full every 2-3 hours) not sure if It’s a good idea to not have the pump skimming right now

    Thanks but doesn’t necessarily explain why after several weeks of marginal improvement took a step back today.

    The Pool that wouldn’t clear...

    Yes. I’ve done the DE exercise numerous times. Several weeks ago, I did it few days back to back actually. Adding DE to raise 1 psi, then monitoring - would last 4 hours or so until 25% increase then I would backwash. Then I would repeat exercise. I’ve done this numerous times.

    1 thing to add...prior to the deep clean of the sand filter, cleaned the ladder and behind the light/niche. Thank you.

    The Pool that wouldn’t clear...

    Hi all. I had another post regarding opening my pool, but that has long come and gone so I’ve created a new thread that hopefully will shed some light on my situation. I opened the pool on May 4 (green swamp). Followed SLAM protocol. Pool went 100% blue within 1.5 weeks, however was still...

    Bullfrog Spa A8 cleaning

    Hi - have a 500 gallon bullfrog A8. Previous home owners bought it a few years ago and I’ve owned it for about a year. About a year ago, I replaced the two filters, drained and cleaned the tub. Since then, water clarity has been great. PH has historically run low which I had been fixing with...

    Planning as much as possible for pool opening

    I never said it was a contest? I’m just trying to get the water crystal clear.

    Planning as much as possible for pool opening

    It’s been 3 weeks and 1 day since opening. Pool has been blue for about 2 weeks. I’ve passed OCLT for about 2 weeks. Marty has also been helping me (a lot - thank you). For some reason my pool just will not clear. I kept slam until I passed OCLT for almost 8 days straight and we realized that...

    New cell question

    The cell is brand spanking new. I think it’s unrelated, but the breaker keeps tripping as well (could be due to some water got in the panel from a rainstorm). Last I checked, it climbed up to 2800...but still 400 short.

    New cell question

    Thanks Yes. Sent to t-9. So what qualifies happy? Above 2500 on the board and as long as its producing? Why is that occurring - is the salt reader sensor bad or something? Crazy to me you can’t do anything about this.

    New cell question

    I installed a new aqua rite t-9 cell. Initially board was reading 2000 salt (verified using my treat kit I should be at 3200). It gave me the check salt/inspect cell and wouldn’t run. I did the instant salinity test a few times over 5-10 minutes (I’d reset to OFF, then back to auto). Each...

    SLAM still Cloudy - CH issue?

    I am in this same situation (SLAM for 13 days). Opened to a swamp and in about a week was blue but cloudy. Yesterday, found a bit of algae in the niche and light. Saw some dead algae settled on the steps this morning. Not a drastic improvement in clarity today but I’m hoping soon...

    Planning as much as possible for pool opening

    Here’s a brain puzzler. Last night, I turned the pump off for 8 hours (thanks Marty - good tip) to see if could get any settling (this was before realizing there was algae in light). Turned the pump back on in morning and did the light cleaning as described above. This afternoon, noticed my...

    Planning as much as possible for pool opening

    Thanks to a tip from Marty, I removed the light. There was algae in the niche. Also on the light (attached). Hopefully this will help my clarity issue.

    I just measured it twice. It’s closer to 35 but I rounded up to be more conservative.

    Planning as much as possible for pool opening

    Day 10 of SLAM. Did aggressive DE treatment all day today. About 2-3 hours after each SE treatment I reached my 25% psi increase and I backwashed. Robot running all day. Just still, seems...cloudy...

    Thanks. Still no discernible change in cloudiness this morning.

    Planning as much as possible for pool opening

    SLAM has been going ... though I feel last 2 days have been a bit stagnant. The pool went from green to blue and most (if not all algae is gone). However, pool remains cloudy and the cloudiness level has really been the same last 2 days. I have been relentless on keeping the FC in check for the...

    How do you measure your chlorine

    I use a clear workout shaker cup ... it has the OZs listed so very easy to measure.
