    Single speed pump vs. Variable speed pump

    At 3/4 hp running at a proper schedule it will take a few years for a vsp to equal the cost, but running your pump 24/7 I wouldn't be surprised if it's 1 year.

    1st SLAM, persistent floor algae

    Over by the robot the floor was clear of debris, you can kinda see a line in the last picture where there is debris and not. Took 3 backwashes and I got most of it with the vaccum. Pic uploader didn't work yesterday and I was buzy. Tested 3 times over the course of the day, if I recall 8, 6.5...

    1st SLAM, persistent floor algae

    I backwashed a few days before, I run my filter from 11->14 psi typically. I started yesterday at 11 psi and now I am at 13. July 5 8:30am test and remove robot FC 7 Cc 1 I think I may have broken the algae production as the fc was dropping faster before, only took 2.5 gallons of 10%. I'm...

    1st SLAM, persistent floor algae

    I'm calling this my 1st slam because I've only had to bump the clorine twice in the 4+ years of tfp style of pool care, didn't really need to hold the fc to fix the problem. I think my problem started last year of floor algae taking ahold in the creases and wrinkles of the liner and inside my...

    Is a 10” intex sand filter too weak for a vacuum?

    Did you prime the hose with the return first?

    Pump peculiarities with the electrics

    Might want to see if they sell a 1/2 hp pump as if they don't the chances messing up impellers is lower Typically those watts meters are inaccurate and only good for comparing.

    Pump peculiarities with the electrics

    My guess is that they use a 1/2 hp motor for both 1/2 hp and 1/3 hp impellers, and you got a 1/3 hp labeled motor with a 1/2 hp impeller Probably wrong

    It's the clorine, and cheap Intex parts, not salt

    Hard to put up pool....

    Most sod cutters have trouble in my area, so a square shovel cutting bricks works. Then I put the bricks in the front yard to grow Bermuda there. Yeah over it

    Would this foam board work?

    Eps works and there is a few members with it, but eps doesn't do as well v water than xps, so if xps is available get that, if it's just a price point.......

    Intex 18’ x 9’ XPS with pressure treated boards advise.

    Find some pavers or pour a concrete footer, wood plus water won't work

    Deck is harder. Just need to make a solar heater and the pool is done for this year. All the other pictures were too big so I'll post them in a update thread laster this week

    1.5" -> 2" PVC for Equipment Pad?

    If anyone would take the time to read the sticky at the top of the page, it clearly shows that....... less head = more watts

    1.5" -> 2" PVC for Equipment Pad?

    If your about saving enegry, you should figure up the head savings, then pull up a head chart and see the enegry cost difference. Spoiler alert, less head = more watts

    1.5" -> 2" PVC for Equipment Pad?

    Aside from adding a swg the only thing you are going to accomplish is more chances for leaks. All of that work will not even show up on a pressure gauge. Two 45's has double chance of making over a 90, and has little effect. The best way to put it is think of two straight runs of pipe, but one...

    Losing suction

    You have something in your filter or pipes after the pump. If it loses suction you would not have any pressure. There is probably a plastic bag in the filter that falls off after off and works it way back to plugging it up.

    Considering a VS motor? Look at the whole system to optimize performance.

    I would think(but don't know) it would be off as the spring inside the case gets compressed, it will compress at different rates at different case pressures. Now, does this matter enough, probably not but as one who loves super precision, it would to me.

    Considering a VS motor? Look at the whole system to optimize performance.

    A low pressure gauge with fluid in it has the air pressure from the factory in the case, which is a different air pressure where you are at, and the air pressure changes over the seasons. A air bleed will zero out the case pressure and the gauge will move 1-2 psi. You only see these on 30psi or...
