All was good a week ago. No led, but salt was down to 3000. I added 2 bags, now 3600. Now the low salt came on. Cell is only 2 year old. Ideas?

I've decided it's well worth buying OEM filter grids (or whole assembly) than buying the "cheap" $150 knock offs! My Pentair grids lasted 8-9 years before one developed a hole, so I decided why not but a new set. Think I paid $125 at Amazon 4 years ago. Look just the same, but one developed a...

Can't believe it's been 2 months since I tested the water! I swim 2-3 times per week, and summer has just flown by. I was really surprised things weren't bad at all. FC is high for the lower CYA level, I guess heat burns stabilizer off (I haven't replaced much water other than evaporation)...

Just curious how clear water should look at night near a light. During the day water looks very clear. At night bottom drains look clear, but near the lights water looks like it's full of dust (or microscopic air bubbles). Normal? My CC is testing close to .5, so there's a bit of something in...

Just a FYI. Buy original Pentair replacement grids when they need replacing! I bought an Amazon off brand 4 years ago. 3 have a hole in them already! I was wondering how oak catkin burrs where getting in my SWG cell.... Good thing I saved my old ones that were 12 years old with only one...

There is no leaking water around my pump or filter, but if I turn off the pump, I get a gurgling sound from the filter (Pentair DE). I turn the pump back on and I need to relieve the air valve. Only thing I can guess is with pump on the large o-ring seals itself. Maybe unseals when off? Or...

This is a follow up after 3 months of use. I thought I started a thread on this, but I can only find a few postings I mentioned this bot. They sell this through Target, and 3 months ago it was under $500, quite a bargain. I throw this in the pool when I see debris on the bottom (once or twice...

Decided to give this bot a try. I have an Aquabot 4WD, 9 years old, never stuck on drains, no repairs, so I have some faith in Aquabot. The only reason I'm trying new bots, is 9 years seems close to end of life, and the 4WD never did walls very well. Received the SP200 today, it's in the pool...

Wish I'd done this 9 years ago to my Aquabot 4WD. Cut 25' off the 60' cable (near the power supply). It makes coiling the cable and storing so much easier. Also easier to untwist when that needs to be done. I pull this out of the pool after its 3 hour cycle which is probably the reason it's...

I got this from Marina Pools, and the Prowler 910 info just seems wrong. Isn't the 910 more like the E10? I have an email to them, but not getting any replies. Just wondering what Pentair model was intended. The Prowler 920 is more like the S200, so probably not that. Why does Dolphin make it...

I'm seeing posts on this cleaner dating back to 2012. Is it still the same cleaner or have they updated it at all? 40' cord is more than enough for me. Just looking for a "cheap" backup in case my Aquabot dies. I don't care about walls or scheduling (I pull it out after 1 or 2 cycles). I'm...

Need a chemical geek. When you mix MA with water, does it stay totally mixed, or does the acid float to top? I use a 4:1 mix in a 15 gallon drum to feed with Stenner. After 4 or 5 weeks, the daily injection seems to be getting stronger. Is that possible? Or has my need for MA decreased?

The specs say the DX3 is much larger, yet they weigh the same, and take the same filter. Is the brush also wider on the DX3, or are they basically the same? Why so many similar models? 😵‍💫. I don't care so much about walls or long cord, just want reliability and easy clean filter.

First day with this, so far, like it! Seems to find the entire bottom. The X11 does walls and waterline, I didn't care about that. Took about 2 hours to charge, probably had some from store. So far it's been running 1.5 hours, supposed to make it 2.5 hours. I'll add picture following once I...

I've been using an Aquabot Rapids 4wd for past 8 years with no issues. I decided to start looking for a bot with cord swivel (the only thing I don't like about the 4wd). Came across this B200. BWT now owned Aquabot, so I assume it will be as reliable. Just received the B200 (Target online)...

Wonder why no one makes a skimmer basket similar to the fine mesh filters in modern robots. Would eliminate need for skimmer socks! Don't like how a sock (or hairy net) covers up the handle. If you know of any, let me know!

Made this from and old jet connection, a 90, a T, and 2 end caps. Sawed a slot across the T 1st. Sawed slots in end cap connecting pieces. Nice sound and aeration. https://photos.app.goo.gl/yEqueStbE25vTXrR9

I'm curious about plumbing in gunite pools. Pool came with house, has a separate line to a jet for vac (which I moved to main pump since I use an electric robot). If I dug down behind that jet, is there usually enough pipe to splice a water feature into? Or is it normally inside the gunite? I...

I installed Edge-40 2½ months ago. Salt had been measuring 3500-3600 until today (hadn't checked in a few weeks). Today's Today it's 4000. Something cause salt to rise?

I've had an Aquabot Rapids 4wd for 8 years, no issues and still going strong. I'm starting to look at what's available today since this thing is going to die. Nothing looks great to me. Requirements: 1. My pool is 32', but I only need a 30-40' cord (I have half the current 60' one wrapped and...

Areas in my skimmer and jets have turned brownish gold over the years. Removing one of the jets (attached) you can see the discolouration. It wipes off the ball, but not some other areas. Could this be dead algae?

I've noticed lately that I'm getting air at top of DE filter (releasing gauge valve lets out air for several seconds). This is with pump running at 2000rpm. It is off at night, but if I release in AM, there's air before end of cycle. I haven't had the issues in the past. Only things I've done...

Only real issue I have since switching to SWG a month ago, is I'm getting a "ring around the pool". Either from salt or calcium. I got my calcium down to 450, but even when higher with LC, I never noticed the line. Nylon brush doesn't do it. Suggestions?

I noticed 5 or 6 round balls (probably from oak tree) down in the 2nd skimmer hole. How to get them out? Short hose to other hole so they land in pump basket? Tried to take photo, but pump is running.

How important is the <1ppm overnight? I've been slamming for 3 days now, and each night I'm getting a 2ppm drop, with CC right near .5. Pool is clear since day 1. Was getting closer to 4ppm overnight drop, reason for slam. Dropped pH to 7 when I started, CYA was 60. Been shooting for FC 25...

I just want to confirm best way to calculate volume of kidney shaped pool. I laid it out on graph paper and my surface area is fairly accurate at 392 sq.ft. Question is depth. 3.5' shallow, 8' deep, 12"r bottom corners. I guessed average depth of 5.5' x 392 = 2156 cu.ft. = 16,000g. Sound...

I'm following slam process and noticed it says too brush and vacuum daily. I have never vacuumed the pool (15 years), I just brush. I use Aquabot to "vacuum" bottom, but don't really want to use it with FC at 25. Not much algae "dust" on bottom when brushing. I assume it gets filtered out...

I've got two 2" ball valves from pool that are getting almost impossible to turn. Not much space to replace. It's there a lube that will loosen them up? WD-40?

I've been struggling with FC drop. Slammed a few days ago at 20, passed all overnight tests. Had been keeping FC at 9 or 10 for a couple days with Edge-40 at at 3 LEDs. Gradually dropped to 6, so I bumped it to 4 LEDs. Noticed it dropped to 4.5 end of day yesterday, and 1.5 this AM. CYA...

My net pole is really old (dents, clamp sticks if tightened too tight) so thinking of replacing it. Does anyone make a light (carbon fiber?) one that has a clamp that doesn't stick?
