    Sand filter let's silt through? Alternative media?

    Clean pressure is around 14psi, I generally backwash around 28-30psi which is what I was told when the pool was new, to backwash when it goes up 15psi. I'm not fully convinced it is a filter issue but common sense sort of dictates that as far as I can tell. I could be wrong but have not heard...

    Sand filter let's silt through? Alternative media?

    It's too fine to rub between your fingers, or to catch to rub between your fingers. If you rub a puddle or collected spot of it with finger against the bottom it is like a very very very fine grit. It basically dissipates when you brush it, into a light cloud that, as it spreads it almost...

    Sand filter let's silt through? Alternative media?

    I am not sure what you mean by "flushed out". You mean when I backwash the filter or flushed out of the filter into the pool? I assume you mean when backwashed. After I have backwashed I still have the same issue. I believe the silt is going through the filter and thus, not collected and not...

    Sand filter let's silt through? Alternative media?

    Yes, from what I learned here I actively monitor and manage my chems using the test kit recommended here. Use liquid chlorine and supplement with tablets when out of town. The pool has a cover and is covered nights and during the day when not in use. Get very little debris in the pool. I put...

    Sand filter let's silt through? Alternative media?

    My pool is about 5 years old and has a cover over it most of the time. Since it was new I have had an issue with silt collecting in areas of the pool. The longer the pump runs the more silt. It's a very fine silt and dissipates with water movement but, of course, settles out again over time...

    FC, CC, CYA and shock question

    That would make a lot more sense. I was pretty sure it wouldn't take quite 5000 years but I am surprised the CYA would add up that quickly ... thanks WJR. I will stick with my original plan and let the tabs bring it up and then switch to bleach. All very helpful information and appreciated...

    FC, CC, CYA and shock question

    That's very helpful, thanks! If that's 6-9 ppm of the volume of the tablet then, if my math is correct (approx 4,5 cubic inches per tablet, 51 tabs/gallon, 18000 gallon pool), it's going to take me 924000 tablets to raise my CYA 9ppm. At 3 tabs a week that's around only 5000 years. I better...

    FC, CC, CYA and shock question

    Thanks for the information TS! I have tried to use the pool calculator but I'm not 100% clear what I am doing but will play with it. I will up my FC tomorrow and let the sun do some work. By "FC 24 hour usage", do you mean see what the FC is one day and then the next (24 hours) check and the...

    FC, CC, CYA and shock question

    Until I came to this forum shocking had been presented to me as a "do it every couple of weeks" thing. Clearly that's not accurate but that's pool builders and suppliers for you. I've read quite a bit here and in pool school and get bits but haven't yet seen it stated specifically (I'm sure...

    How to check sand level in Cristal Flo II sand filter, think builder under filled

    Long story short. I have very little confidence the pool builder we used. It seems our Cristal-Flo II 3.15 sf allows a fair amount of either sand or silt through the filter and back in to the pool. I suspect it's silt because when brushed it disperses easily (my readings here indicate that is...

    Easy Touch 8, How to get lights and equipment to communicate with panel?

    I have figured out the lights, it's just a matter of programing the Aux they are connected to to associate with the intellibrite system. Pretty slick actually. I think I have a handle on the VS pumps (just need to get the comm lines for the pumps and wire directly to the breaker rather than...

    Easy Touch 8, How to get lights and equipment to communicate with panel?

    Short version of long story. Pool builder has basically quit, I am finishing pool myself. He had brought out all the equipment and automation parts and I am trying to figure out how to get the automation going. I did get an electrician to do a basic and safe wire to the EasyTouch 8 panel...

    Correct Light Installation IntelliBrite Color? Blob of tar on connection???

    Thanks Dave. I assume then that the bonding wire is bonded to the backside of the niche and in the concrete? I think I now recall that and it did have an electrical bonding inspection so I probably can assume that is alright. I am guessing the black stuff is indeed to stop corrosion. What...

    Correct Light Installation IntelliBrite Color? Blob of tar on connection???

    My pool builder has basically abandoned the job at 95% complete (fixing all the screw ups is going to cost him much more than I owe) and I am trying to get it finished myself. The lights (spa and pool, both are intellibrite color, 120v) were installed, wired to the J-box and then onto the...

    Builder forgot supply line for water features - Plan B?

    Only have the one skimmer. The builder just basically filled the gunite around the skimmer and let the second line seal with it so I don't thing that is an option but I will see if there is anyway to clear it. It should be at or near the outside edge of the gunite. I did think about the debri...
