    Chlorine at high water temps. Keeeping water safe.

    Greetings! I installed a ridiculously huge solar heater and now my pool hits 90-92F easy. My cya is 30 so I maintain 6ppm chlorine, but I’m not sure that is sufficient to keep my water bacteria free. Is there a chart to show me what I need to follow that takes temp into account to keep things...

    I have thought up one additional question. Why would algae form if my choline levels are high enough? Could it be lack of water movement? Thanks!

    I had no idea that CYA would breakdown. I've got allot to learn. Thank you for the reply.

    I'm sure I'm not the exception. Thanks for the reply. - - - Updated - - - I did a complete drain and fill this past spring. I only added enough cya to achieve a 15 cya. I only added like 16oz of it. I agree there is no way to test down to 15. At most I'm at 15. I've never added anything to the...

    Hello, I'm wondering what is going on with my pool. I'm getting some minimal green along the circumference of my pool. Its like dust. Not overly sticky. Walls feel clean and not slimy. 18' above ground. All I add is liquid chlorine 10.8% and I maintain 3-3.5 daily. The water is clear. I us, e a...

    Pool Hydraulics-Solar heating. I want to do the right way first.

    I'm planning on 2 collectors each with 200' x 6 of poly pipe round and round. I have no idea how I could make that self draining. A disadvantage I see is if the collectors drain every time the pump is off the pump would need to prime them. I am planning on blowing them out at the end of the...

    I'm planning on using municipal water supply to prime the system at the start of each season. Just trying to think of everything so less comes up that I didn't think about. Thanks mas985!

    Has anyone encountered any problems with air lock on any type of solar heating setup? Thanks!

    Pool Hydraulics-Solar heating. I want to do the right way first.

    I found a dramatic error in the math I have done. a 2" id pipe has a surface area of 3.14sq''. the surface area od a 1/2" pipe .6''id is .28sq". I would need just over 11 1/2" pipes to not create a bottle neck. I am going to use six 250' 1/2" pipes in parallel for each collector. 2 collectors. I...

    Holy! I read that a few times and cant fully wrap my head around it. Is the answer, yes 6-1/2" pipes would be OK because water velocity would be reduced because of the larger collective diameter of the pipes? In school I counted 9 fingers. 0, 1, 2, 3...9. What do you mean you don't count zero?

    math question. I have 50' of 2" poly heading up to my roof (12'). The plan is to have a manifold to branch 6 1/2" (.6"id) poly pipe each 500' long. Then back to a manifold, back 50' through the 2" poly. The total id of the 6 poly pipes is 3.6". I understand that there is loss from friction...

    Basic questions about necessary above ground site prep. Easy stuff really.

    Hello, first I'd like to say thanks for contributing to this awesome site. Second, I did search for answers, but nothing I read addressed these questions directly. 1. Is there a maximum amount of sand that should be under the pool? 2. Can the paving stones that go under the legs be resting on...

    OD of the pipe is .7", not .5" that's the difference. I understand that will only with the sun at the perfect direct angle.
