My pool after 15 years has developed a crack in the concrete shell: An overall view of the corner: The crack also extends to the other side of the corner. I need recommendations on how to stabilize the crack. Thank You in advance.

Is there any way to mark all posts as read?

I have a solar heater controlled by my AquaPlus controller. The controlling valve is a three port motor operated valve. Recently it looked liked the solar heater was not working i.e. the pool was not warming up. A couple of years ago, I had the same issue, and I replaced the internal parts of...

I have a Dolphin A30i which every week I roll out, plug in and put the cleaner in the pool every Friday. It then does it's scheduled cleaning cycle. There has been a contractor working in our neighborhood repairing the sidewalks. Last Friday, he not only managed to dig up my Internet connection...

Does anyone know how to change the default standard cleaning cycle when creating a weekly schedule on the MyDolphin Plus app? When I configure an operation for a certain day of the week, say Friday, the only thing I can change is when the cycle starts. I can't change the type of cycle or the...

I decide that I would again try to test various robotic pool cleaners. I managed to local demos units for both the Maytronics Dolphin and the Polaris line. All were tested in my pool with at least two cycles. For the last two units, I put dirt into my pool (my wife screamed at me!!!) to see how...

I really want to purchase a robotic pool cleaner. Both of the above companies will not accept returns of used cleaners. Several years ago, I demoed a Dolphin 300I. I would not clean the short side of my L shaped pool. I did call Maytronics at that time but never resolved the issue due to the...

A bit of a gloat thread. We remodeled our master bath and replaced the existing oval garden soaking tub with a corner whirlpool tub. Color balance is off, tub and tile are all white. Looks and works quite nicely.

We are in the process of getting our existing old garden tub replaced with a new whirlpool tub. This tub will be filled and emptied with each use. I recently saw that cleaning this type of tube is different from a regular soaking type tub. Most recommend filling with hot water, adding some kind...

I don't know if this is the right place to post this. We currently have a large single person Jacuzzi tub in our master bath room. We are going to replace it with a whirlpool hot tub / spa. We are looking at tow types. The first is a corner mounted drop in hot tub more in line with a regular...

I have a Hayward CX12002 filter on my system. Several weeks ago I noticed that it was leaking between the top part and the bottom part. I opened the unit up and the o-ring gasket was in very bad shape. The unit is about 12 years old. I purchased a new o-ring and some gasket lube. That seemed to...

I have a small in ground "L" shaped pool. Last year I tried several Maytronics cleaners, and neither of them would clean the small end of the "L". I still want to get a robot, but the fact that two Maytronics failed on my pool, the draconian policy for pool cleaners (you bought, you own it, no...

I am going to replace my existing halogen lamp with a LED model. In studying the available options I have found the below and would like to know if anyone has experience with any of them. WYZM Bonbo White P&LED Bolaxin

The pool light has not worked for some time, so recently I had some free time, and I decided to get it working. First the relay in my AquaPlus controller, was clicking in, but not passing electricity. I have problems wit ants getting it. I changed our the relay, and then found that the...

The diverter valve on my solar heater has bit the dust. The cover and swing arm (inside the valve) are badly worn. The problem is I cannot see who the manufacturer or part number is. This information appears to be on the backside of the valve which is against the wall of my house. I went by my...

My last two cleaners are/were suction side cleaners. My current unit is a Pentair Great White. Unfortunately it is suffering from advanced age and will soon need to be replaced. I have been thinking of going with a robotic cleaner as I believe that setup and take down will be simpler. Some...

I have been vacuuming my pool with either a suction side cleaner (Great White) or a pad with the same suction hose. The pool is in a enclosed screen cage, so normally does not get real dirty. Most of the time it is just some sand/dirt in a one corner or the other. It is a hassle to get out the...

My in ground concrete pool has a leak. I am loosing about 1/4" of water a day with the pool cover on. So I have to a) find the leak and b) repair it. Some background. When we first filled the pool, it drained down rather quickly. The pool contractor discovered that one of the bottom drains had...

Spent all of last week reducing my TA and balancing the pools chemicals. Yesterday had over 3" rain in less than one hour, entire backyard was flooded including the pool. Now I have to start over! Sigh!

The movable, floating (used to be) door between my skimmer and the pool has lost its foam and so no longer closes when the filter shuts off. I have some Styrofoam that I can replace the old However I would like to know what adhesive I can use to attach the foam to the skimmer door with? I was...

I have a Pentair Great White suction side cleaner which I have had for a number of years. Recently it has developed a problem that it will not stay flat on the pool bottom. The front, which has the bumper bar lifts up off the surface. Any ideas as how to correct this?

I have had my PebbleTec pool for about nine years. There has been a consistent problem in that if I let the FC go below 5, I start to get growth in the pool. According to various tables on this site and also other places on the web this should not be so. Anyway last week I started to get green...

I have a solar heater which is controlled by a three way valve. Recently (in the past several months) I have noticed a noise similar to cavitation or turbulence coming from around that valve. Filter pump is still working correctly, filter pressure is still at its usual level, no discernible...

This is off topic for a swimming pool, but I would like to get the chemistry experts to weight in on this. As part of my work, I am setting up a titration type analyzer which measures total alkalinity in mg/L as calcium carbonate. This analyzer uses a standard alkalinity solution as part of its...

I have a Pentair Great White pool cleaner. In the ladt six months this cleaner has developed an issue with the front end wanting to lift up off the bottom of the pool. Has anyone encountered this problem. I have been thinking of adding some weight to the front bumper bar.

It doesn't rain but pours. Been on vacation for a week, so pool without maintenance for two weeks. Now both the pump bearings AND the SWG cell are bad. Will pull the pump this afternoon to start to change the bearings. However I would like some advise or testimonies on a replacement Hayward T-15...

The TA in my pool raises slowly over time. The pool is about four years old, and I do not add baking soda. About once a year I have to perform the TA reduction process. I would like to know possible causes of increasing TA.

My pool has sprung a leak. This evening I will try and determine where the leak. However I believe that it is probably in one of the main drain fittings. When we first filled the pool several years ago, we discovered that the pool was leaking. The pool contractor found that one of the main drain...

Hello; I noticed what looked like two small spots of black algae on the top wedding cake step. Brushing with my regular nylon brush would not remove the spots, so I purchased a small stainless steel brush. This removed the two small spots. As I was brushing I noticed a white cloud rising...

I have an old Kreepy Krawler type cleaner that is showing it's age. I would like recommendations and suggestions for a suction side pool cleaner. My pool is "L" shaped with a bench at one end of the "L" and a weeding cake step at the other. The skimmer/suction port are located at the corner of...
