    What is a good size for a L shaped pool?

    15x30 for a shallow end sounds pretty ample to me. However, I don't know how many people will be using your pool or how big a pool you're looking for. For some comparisons, alot of the pools we saw when we were house shopping a few years ago were in the 16x32-36 ish range. Your shallow end...

    FC Loss Each Day

    lol. This one never seems to work for me.

    Sudden Rise in PH and TA...Not sure why?

    I guess, I'll add why, I suggested waiting. Mainly, because when making adjustments its usually best to changing one thing at a time. This give you better control of whats going on and more predictable results. In this case getting the pool back to normal maintenance mode. Then making a TA...

    Sudden Rise in PH and TA...Not sure why?

    Me personally. I'd retest. But I'd wait a couple of days. Get your FC back where it belongs and get back into normal maintenance mode. Your pH is in range and the TA isn't going to break anything in a couple of days. On occasion, I'll get a test result that is unexpected or unexplained...

    Finding the flow curve

    *UPDATE* Just figured I'd give everyone an update. The new filter is installed. I got a Pentair Clean and Clear Plus 420. (The Hayward and Pentair models are so similar, it didn't seem like it mattered which I chose). At any rate, the numbers Clean Filter PSI 9 Vacuum Hg 10 Using the math...

    Finding the flow curve

    Oh one more question for your Mark. You say you only clear your filter about once a season. Is that using that 1-2psi rise guideline you mentioned in other posts?

    Finding the flow curve

    Thanks again guys. That info about your filter is good to know Mark, once per season is exactly what I'm looking for. Those other reasons are good to know and a great bonuses to boot.

    Finding the flow curve

    Not sure if I should post on this thread or start a new one. If I need to start a new one let me know or split thing one off. I've been wanting to replace my filter for awhile and this is kind of an excuse to do so. I don't know, something about using all that water to backwash was the filter...

    CH through the roof! CYA high too, 50% drain my only option?

    Re: CH through the roof! CYA high too, 50% drain my only opt Reverse Osmosis (RO) is another option if its available in your area. Although, its more expensive as I understand it.

    Finding the flow curve

    I'm trouble finding a vacuum gauge. The local auto parts places don't seem to have them. Even the kind that come on a break bleeder kits. I'll just order one online. If it hasn't been said, thank you Mark and Jason. As always, your opinions and advice are both appreciated and valued.

    Finding the flow curve

    *sigh* Well, I appreciate your advice and expertise. I'll still check and confirm it. At least then I'll know. To to fix this I can, replace the impeller, pump or filter?

    Finding the flow curve

    There was an assertion that my equipment (filter and pump) are mismatched. Because the flow rate of the pump exceeds the maximum flow rate of the filter. When I attempted to discuss this point, I realized I don't have enough information about my system to be able to do that intelligently. The...

    Finding the flow curve

    Thank you. I guess I need to calculate the actual head of my pool, so I can get an accurate flow rate. My filter clean is 15psi using that formula from the hydraulics page. It gives me 37.65 on the return side. For the suction side, I'll go and get a vacuum gauge after work. I do have a...

    Finding the flow curve

    Hey guys, I'm trying to figure out what the flow curves are on the pump I have. There is a metal decal on the impeller housing that reads: Model Number: P2RA5E-124L Code number: IL89S STARITE INDUSTRIES. I can't seem to find information on this particular pump. Apparently its been replaced...
