    Chlorine usage high. Again

    I have a Intelliflo VS so I have variable speed settings throughout the day. I do about 2.5 pool turnovers per day. The pump is completely off from 11PM till 7AM.

    Chlorine usage high. Again

    Yes. twice a day about 7 minutes of runtime each time.

    Chlorine usage high. Again

    I don't know how to confirm that. I have done a FC test before and after adding a measured dosage and verified the FC increase was on par with what Pool Math says it should be. The chlorine does sit in a translucent Pentair dosing tank throughout the week (4 gallon capacity) and it is exposed...

    Chlorine usage high. Again

    Thanks guys. My pool does get a lot of sun and this time of year I don't have a solar cover on it (if that blocks UV). Should I be concerned with the OCLT loss of .8 the last time I did it? I also wonder if my darker liner has anything to do with burning off chlorine quicker. Higher temps...

    Chlorine usage high. Again

    it’s been about a month since the last OCLT. I think I lost around .8 PPM overnight. I really don’t have a lot of spots for organics to hide. Just the 2 main drain covers maybe? Could algae under those really use up that much chlorine in 1 day though? I can check them. Not sure if the covers...

    Chlorine usage high. Again

    How would that lower my additions? Doesn’t higher CYA protect it from being used by the sun?

    Chlorine usage high. Again

    Okay... I have posted about this before but now I am calculating my chlorine usage at about 4.1 PPM per day. I go through just over 4 gallons of 12.5% per week! This just seems really high to me. I passed the overnight loss test and CYA is at 50 so what’s the deal? I see people at the pool...

    Shock levels vs slightly elevated Levels

    Great. So higher levels take care of it quicker. I like the pattycake reference. haha. Its my understanding that the CYA chart Shock levels on this site are still actually safe levels for swimming. Correct?

    Shock levels vs slightly elevated Levels

    What makes the recommended shock level so special? Is it not enough to just raise FC to levels to an elevated number not necessarily at shock level? I ask because I have a slightly cloudy pool after letting it dip below minimum FC levels for a little while. I promptly raised FC to around 15...

    Chlorine from dosing tank

    I had another post with concerns that my daily chlorine usage seems way too high, but I guess I may just be at the high end of normal based on responses to that post. To maintain my levels I have to add about 4 PPM per day. That got me thinking. I have a pentair dosing tank that is somewhat...

    Chlorine loss per day?

    Thanks guys. It just seems like I keep having to increase my chlorine pump run time to keep up compared to last year. Also, last year my CYA was 30 and I upped it to 50 this year in hopes it would slow down the usage rate.

    Chlorine loss per day?

    I know this is very dependent on location, bather load, etc but I am wondering how much chlorine loss you all see on an average day. Not sure what a good universal measurement would be for that. Maybe how many PPM you add per day? Or ounces of liquid added per 10,000 gallons? I seem to lose...

    Calcium Hardness, vinyl liner, saturation index, gas heater

    I see a lot of posts and recommendations on here that say CH levels do not matter in vinyl liner pools. I understand that it will not affect the liner itself. I am curious though about the effects of a low saturation index on pool heater exchangers and cement pool decks. Many other sites...

    Dark liners and effects on heating the pool

    This is just an observation of mine relating to having a darker liner and how it effects the pool temperature. Hopefully it is helpful to someone else in the future when trying to decide. When I was researching this during our pool build the opinions I found were that the effects of a darker...

    Some questions /thoughts about CYA

    I have the PoolMath app on my phone. With CYA at 50 it shows a target of 4.0-8.0 That app was developed from someone here right? Are you saying a target of 8 because you like to keep it at the higher end of the recommended range? Should I aim for 8 when adding chlorine so that during the day...

    Some questions /thoughts about CYA

    So my pool just started getting cloudy yesterday which I assume was an algae bloom since all my other levels seem to be in check. It was a surprise to me because I thought my CYA was around 35-40 and I haven't let the FC go below 3. That got me questioning my CYA levels again. Cue the super...

    Codes for string / bistro lights around pool patio?

    Codes for string / bistro lights around pool patio?

    I cant seem to find any solid information on electrical code for hanging lights around the pool. I see some references to 10 or 12 feet of clearance if hanging above pool but what about around the pool? Is there a certain distance requirement from the waters edge if the lights are under 10...

    Feet of head

    Intellifo VS. Not the VSF. Its my understanding that the VSF will display flow but not the VS.

    Feet of head

    You rock. I used your calculation estimates as a part of a excel document I made for myself to figure out turnover rates and energy usage based on some other metrics unique to my pool. I would attach it but it does not allow XLS files on here.

    Feet of head

    Thanks MAS985. I have always been pretty good at math but this whole thing is not clicking in my head. I am comfortable with trusting your numbers though :) What confuses me is that I thought feet of head was a static number that was figured out and that the flow rate was determined by feet...

    Pentair ScreenLogic Alexa Skill GONE

    Yup. I used the skill only 5 days ago and then yesterday it said its no longer available. I have my system setup with a custom controller and integrated into SmartThings thought :) Always liked Google better anyways.

    Feet of head

    Mas985, Here is my best estimates and measurements filter pressure at 3450 RPM is 29 psi Gauge is about 5.5 feet above water level. there is a main drain suction run and skimmer run. Main drain is about 50 feet and skimmer is about 45 feet. Both are 1.5” lines and run into a 3 way valve just...

    Raypak Heater temp readout

    I turned it off for a couple minutes and it did not go back down but I don't know how often it is polling the sensor. I am running the Intellifo VS pump at 2100 RPM while the heater is on. There is no external bypass.

    Raypak Heater temp readout

    That was my though initially as well. But no. It is plumbed correctly. When looking at the side of the unit the water goes in the left side and our the right. That is how the manual shows it as well.

    Raypak Heater temp readout

    I have my new Raypak 266k heater running and just ha done thing catch my eye. Before the heat was on the temp readout on the raypak matched what my easytouch readout was saying. Now with the heat being on the Raypak temp readout is reading 10 degrees warmer than the easytouch. The Easytouch...

    Easytouch programming with Heater

    I think I found my answer to number 2. I set one of the pump circuits to "Pool heater" and set the RPM. Is this just a label for a certain RPM or does it actually activate that circuit when the pool calls for heat?
