I'm wondering if anyone has tried this or what the thoughts might be. Our tap water has a moderate amount of calcium, but since I live in Sunny SoCal and we get only a little rain water in the year, but do get evaporation and refill, over time our Calcium level gets high. After the bit of rain...

Our city water (Lakewood, CA) is fairly high in Calcium and living in SoCal where it's always sunny we deal with a fair amount of evaporation. We do use a cover for much of the summer, but by the end of pool season, our Calcium gets up to the higher ranges. In the last few years, we've gotten...

Since I live in sunny/dry SoCal, don't have much of an issue with Algae. However, we have a gazebo and dew collects on it every night then it drips down onto the deck/pavers. In a few spots that has caused some algae to start growing - just wondering what's the best way to kill that and get rid...

So we planted this moderate sized plants when our pool was finished not quite 2 years ago in the planter that was integrated to go behind our waterwall feature: This is what they look like now: They are beautiful but the trunks of these things keep growing and are huge - I'm concerned about...

I have had my s300i for about 2 weeks. Got it from Marina Pool & Spa of course. Today noticed that I started a 1.5 hour Ultra Clean sequence. Went on walk with dog for 30ish minutes, got back. Robot was just sitting there. Light Ring on Power Unit was red. I opened the app and connected...

So a couple of weeks ago I started to notice some white flakes at the bottom of the pool on occasion. Since we had recently had an issue with our cover losing buoyancy and water getting on top of it then evaporating and leaving salt deposits behind I thought it was that... But after we...

I keep reading about robot vacs that have "smart scanning" navigation to make sure it doesn't clean the same area 10 times and then totally miss another area. Currently, I use a Hayward Navigator Pro Vac cleaner - it does a good job of grabbing debris. The issue is it has a built in random...

So, I just noticed (or re-noticed) there's a hole in the back sidewall of the skimmer. It's relatively high, like at a height that would be considered the highest the water level should ever get to. This leads me to believe it's some type of safety drain to keep the pool from ever overflowing...

I want to empty some of the High CH Water out of the pool before we get rain so I can lower the CH - not a lot of course, just enough to allow for the rainwater to refill. Our system has a manual valve located after the filter that when opened has a pipe that leads to the house drainage system...

I've spent a few hours (don't tell my boss) researching solar panels because it's killing me not to be able to use our pool for so long. I wish our builder had talked to us more about adding them in the initial install, but he made it sound like a gas heater would magically heat the pool for...

Our IC40 SWG seems to be working fine. Our pool is new and everything was started up in July of this year - I had marked on my calendar to clean the SWG this week - I can't remember why, but I feel like somewhere (manual or something) I read it should be checked/cleaned every 4 months. Is that...

We have the Pentair Mastertemp 400btu Gas Heater - 12,000 Gallon Pool - Pentair Variable Speed Pump and Intellichlor40 SWG. We have 3 Pool Floor Returns specifically for use when heating the pool. We've used the heater several times so far and just trying to get general info. The Pool Setup...

I'm currently running our Intellichlor IC40 at 60% Output with our pool filter running 7 Hours a Day at 1900 RPMs. This seems to be keeping our 12,000 Gallon pool at the optimum 4ppm FC with the current sunlight/weather. My question is simply whether it's fine to run the IC40 at 60% or if it's...

So this white streak showed up by our steps seems like almost overnight. No idea what it is or why it's there or what to try to do to remove it. I don't think it could be a calcium deposit. Our CH is a little high at around 500 right now, but our CSI is excellent and there is no sign of calcium...

So, our fill water has a high CH - it's in the 400 ballpark. Of course as water evaporates, the calcium stays behind - then we add more fill water with more calcium and so slowly over time I know CH is going to get high. We're about 2 months after initial fill now and the CH has climbed to...

I'll admit the first time I opened my TFT-100 Kit, I was very overwhelmed. But I've been taking it step-by-step, seeking advice here when needed, and things are going great! The first 4 weeks were hardest, wanting to protect our new plaster and scared to death any wrong move could ruin it for...

So, during construction I was concerned about the cost of water for the initial fill of the pool. As it turns out, that was relatively cheap. What I should have been concerned about was the cost of running the pump for the first month. Our PB had us run it on high 24/7 for the first 10 days...

As we are just now starting to use our new pool, I'm just curious if there are specific sunscreen chemicals that are REALLY bad for your pool chemistry and/or if there are certain sunscreens to look for that tend to be better for your pool chemistry. I had read to make sure people let the...

I know the Yellow Color Coded Free Chlorine test is supposed to be used only to know that yes, you have a decent amount of chlorine or no you don't have hardly any chlorine, but just how inaccurate is that test? I ask because it seems to me like my Chlorine level on that test is always in the...

Pool was finished about 3 weeks ago. We have a schedule set up to run the pump from 10pm to 9am. Otherwise, we just turn it on manually if we need extra cleaning or something for now. (Later we'll set up a schedule for the robovacuum as well.) Today, checked in on the pool via our Arlo and...

Did my first CYA test today after the PB supplied Pool Guy added CYA for the first time about 6 hours ago. The black dot did not disappear, however by the time the tube was full it did look a lot like the middle picture on here: Why Monitor Cyanuric Acid? The black dot was not as clearly...

Newbie here - haven't added salt to our pool yet - couple of weeks off from that. Just wondering does an SWG get turned off or can it or do you just turn off the % of production? I assume we'll have the SWG on and producing the right % of chlorine based on our regular pool schedule. But when...

We're still a couple of weeks away from being able to drop our little robovac into the pool, but I wanted to ask a question for getting our automation system set up correctly. We have a dedicated wall vacuum line that we'll be connecting our Hayward Navigator Pro to. I'm assuming that for...

I went out of my way to go to Lowes and get Full Strength 20 Baum MA last week. But after using it, I'm wondering if it makes sense for me to do that. We have an Orchard Supply Hardware (5 min drive) and a Home Depot (10 min drive) right by our house. Both have the "pool version" of MA which is...

Our pool build included a dedicated Vacuum Line. We've been using it with our hose and manual vac for a week, but then the PB installed a Vac Lock on there (which I guess is a good thing), but the Vac Lock has a smaller opening than Vac Line itself had and now our vacuum hose doesn't fit. Seems...

Plaster and initial fill was 4.5 days ago. Pool Guy has added Muriatic Acid to reduce pH and TA and we have been monitoring. TA still needs to come down and it looks like pH (as I heard is common) is creeping up so we will likely add some Muriatic Acid ourselves (according to Pool Math) this...

Our pool was plastered on Saturday - Quartzscape. There has really been no plaster dust at all. We've been brushing it twice a day and the pool guy (provided by builder for 1 month) has vacuumed it a couple of times, but other than a little initial debris, we haven't seen any plaster dust. I'm...

We are on Day 3 after plaster (quartzscapes). So far the Pool Guy (provided by the PB) has added Muriatic Acid to work on getting the pH and TA down. He doesn't return for a week so it's on us between now and then. I tested yesterday evening and the pH is 7.2 and the TA is 120. As I...

So after reading these forums for several months I am well aware that one of the biggest things you have to deal with after plaster and fill is the residual plaster dust. So I bought a wall whale brush (in addition to the standard brush the PB provided) and we've been brushing twice a day as...

Did my practice testing today with water from the hose (which will be used to fill the pool). Here are the results... Chlorine showed basically 0 pH was about 7.8 Calcium Hardness was 250ppm Total Alkalinity was 160 The CYA test - well, I assume there's no CYA in my tap water, but I did it for...
