I want to know if there is an automation system that is capable of reducing the speed of the pump after the solar speed is activated. The reason why I want this option is when solar demand turns on, the pump needs to run at a high RPM to make sure the panels on my roof are fully primed, but...

My robot, about 4 years old, would not remove the fine dirt from the pool until I replaced the ultra fine filters. On close inspection I could see some very fine pin sized holes in the filters and I'm guessing the fine dirt would go right through the filters and stay in the pool. The filters...

When is it recommended to change the brushes on a robot? I've had mine for a few years now and it doesn't seem to pick up as much as it did when it was new. The impeller is free of debris and overall the robot is still in excellent condition. As noted below I have Dolphin S300I.

I can't find anywhere in the forum where we have actual data about SWG's and low flow rates. What I'm looking for is the brand of SWG, pump specs, minimum RPM or flow that the SWG works, and your estimated flow if you know it. Many manufactures don't stat their minimum flow requirements and it...

My pump is not starting when high-speed is selected to turn on the pump. The pump makes a loud buzzing sound when trying to start the pump and then the thermal cutoff switch shuts the pump off after a few seconds of trying to start. The pump makes the same noise when starting on low-speed, but...

Pros and Cons of a SWCG Pros: • The convenience of not having to haul and add chlorine daily • Chlorine is more consistent over a period of time. Eliminates the trouble that can be caused if the normal chlorine dose is missed for a day or two • Able to go on vacations without the need to have...

I'm replacing my old timer with a new intermatic T10604R control box. My question deals with the length of the original wires. The new box is larger and I don't think the heater wires that are connected to the 240V lines will be long enough to reach the terminals on the new timer. Will I be...

I know the FloVis can be retrofitted in a Jandy 7305 check valve, but will it work accurately in a Jandy 7512 90 degree check valve? I've been having problems with my SWG flow on low speed, sometimes it works other times not enough flow, and I'm wondering how close my system is to the 30 GPM...

I'm not interested in keeping the water warmer during the winter here in SoCal, but I'm interested in what you think about shutting off the solar panels during the winter. I do not close the pool and we use the spa 3-5 nights a week. My question is, will the panels stay in better shape if I...

There should be a link in Pool School that explains WHY we recommend a proper test kit. A lot of times newbies get bombarded with suggestions to buy a new, better, more accurate test kit to fix their pool. Most of these newbies have been "pool stored" already and then we want them to spend...

I'm wondering if anyone who has the new Jandy tri-sensor with the board addition has had it fail yet? If so, how old was it? I know that there have been a lot of failures lately with the tri-sensor but I believe they are the old models without the board.

How much time do I have to read the pH and CYA tests after they have been mixed? Also, will CYA read higher with 90 degree water compared to 70 degree water? Thanks!

Ever since the server upgrade the spell check does not work for me. Is anyone else having this problem? The spell screen pops up and it is blank with done at the bottom.

I have a 16 month old aquapure and my readings have always been higher on my aquapure than my aqua chek strips. My aquapure measures 3500ppm and my old strips measured 3000ppm. I just ran out of my old strips and the new ones measure 2700ppm. I ran the new and last old test strip at the same...

I am wondering if this is the type of spot etching you guys are talking about. The pool is almost one year old and it has this white splotching around the steps and swim-outs. I have always tried to keep my csi on the lower side 0/-.35ish. I have never had the need to clean my SWG yet. The...

This summer I had to run my pump for 15 hours and have my SWG output set to 80% to maintain proper FC 5ppm for my CYA of 80. Does that amount of pump time and % seem out of the ordinary? Background about my pool: The pool is not quite one year old. Swim load is on the heavier side for a...

I just checked my in-laws pool and have some interesting numbers. It is a 30 year old gunite pool with the original white, ha ha, plaster. The plaster is still smooth but is mostly stained with different shades of colors. They like the look, as it just isn't a small stain here and there, but...

I have a question regarding the OCLT reguarding if I passed the test or not. My results from this morning and Monday morning are a little mixed. On Suday night to Monday mornings OCLT I got the following numbers: 25ml test I had 30ppm to 28.4ppm for a loss of 1.6ppm. With the 10ml test I...

Hi everyone, my first time posting but have been reading on this site since my pool was built in November, 2010. We live in Long Beach, CA. My numbers first: FC 24 CC 0 pH Lowered to 7.4 at start of shocking was 7.6 TA 90 CH 230 CYA 80...
