    Pool Water Quality Testing Research Project

    I test for all the basic conditions; pH, Free Chlorine, Alkalinity, Hardness, and because work involves waste water management, I also test Turbidity and Conductivity and Dissolved Solids.

    new to the sand filter world

    Sounds normal to me. I've been using a sand filter for a few years now. Clean pressure is about 17psi and at about 23psi. I need to back flush. it's not uncommon for me to need to back flush after vacuuming, sometimes during depending on how dirty the pool is.

    Hayward Super Pump

    Those were very good assumptions James. I was used a temp probe located just inside both vents the side the air was going in was about 150 to 155. the other side would max out the thermometer at 170, so I assumed it was probably running at 180 or something around there. Your guide is about...

    Hayward Super Pump

    Hi everyone, I have a few questions about the used Hayward 3/4hp Super pump I just bought on craigslist to replace the 1.5hp doughboy pump. My first question is are there advantages to running it on 120v vs' 220v? Second question is Hayward seems to run hot (about 180F), is this normal? Third...

    Hard pool cover

    I've been thinking I can build "trusses" out of 1/2" conduit that will form a roof frame and then cover with vinyl corrugated panels. The plan is for the roof to be slid on a track/trolley Away from directly above the pool for use and pushed back over the pool when not in use. The pool is ag...

    high pressure

    Thats good info Linen. Does "Model 1600" mean anything? It does list the size just that it holds 150lbs of sand, filter area is 1.4sq. ft. Thank you, Cory

    intex filter pumps

    "better" could be defined in many ways..Sand filter maybe easier to clean, and maybe less expensive to replace. I had a intex cartridge filter and got so tired of needing to clean it almost daily.

    high pressure

    The pump is a Doughboy Power Pak II. The filter is a Doughboy Media Master Series, high rate sand filter, Model 0-1701-016 I did find through the weathered label to backwash when gauge reads 5-7psi above clean pressure. it says that max pressure is 25psi, it runs clean just under 20. I guess...

    high pressure

    thats the pressure its been at in the year i've had it. The lable reads it needs to be backflushed when the gauge reaches 7psi.

    high pressure

    ok, so any opinions on what is causing the pressure to be so high?

    high pressure

    Well I guess I thought that the old sand was restricting the flow of water causing the high pressure.

    high pressure

    last year was my first year with a pool. Which I bought used, spent the last season with 15-20 psi at the filter. Thinking the sand needed replaced I changed it today with no change in pressure. Its around the same pressure when back flushing, yet I can make the gauge pressure change by using...

    Eclipse 3

    I saw in most resent pool supply catalog a product called eclipse3. Anyone use it? Sounds simple to use. It's advertised to be used by 6 flags. Not really sure how the cost compares to the BBB method. Last year was my first year and it seems like I added a lot of bleach. Or the pool was...
