    (Updated Title) Sudden complete FC loss due calcium chloride

    As I mentioned in my post above - at midnight I was around 5 (maybe a touch higher, tough to tell under a light bulb), at 8.30am I was at 4.6. So that was fine. What happened yesterday and then again today between 8.30am and 3pm is the issue. I even cleaned the salt cell last night to ensure...

    (Updated Title) Sudden complete FC loss due calcium chloride

    @JoyfulNoise - I used SunCoast Calcium Hardness which uses Calcium Chloride Compound 100% @revitup - I've seen some of the reports here that adding calcium chloride caused FC drop but every single response seems to be that it's not correlated. But see what I wrote below, it has to be. I have...

    (Updated Title) Sudden complete FC loss due calcium chloride

    @Newdude , thank you but I don't think that's it. I went through that entire process a month ago. It took 2 weeks but I got the Chlorine to be steady at 4.5-5ppm and it held there for over 2 weeks. The only thing I've done over the last 48 hours is add 12lbs of calcium increaser, 2lbs per bucket...

    (Updated Title) Sudden complete FC loss due calcium chloride

    Ladies and gents, I'm stumped. After treating my fiberglass pool for iron with ascorbic acid 5 weeks ago, I had mostly re-balanced it. FC was steady at 4.5-5 for 2 weeks, alkalinity was 70, PH 7.6 CYA 60. The only thing that was low was calcium so I raised it over the course of the last 48 hours...

    Stain removal from fiberglass walls

    My heat pump has a titanium heat exchanger but it's bypassed anyway. I've brushed it every 30 minutes in between work calls and I have the pump running at 2k RPM. I guess I'll have to wait and see. Thank you again!

    Stain removal from fiberglass walls

    @JoyfulNoise, I'm afraid I need to bother you with another question. There was no chlorine left as of this morning, PH was 7.2, added Polyquat last night and circulated the pool overnight. This morning I added 1lb of ascorbic acid from NetworkRX and let it run for over an hour. Could not see a...

    Stain removal from fiberglass walls

    Thank you, @JoyfulNoise ! They are definitely iron. My kid wrote her name on the wall with a vitamin C tablet...it was pretty funny to see a 5 year old test the source of staining :) I just wasn't sure if the effect on the walls would be similar with the effect on the bottom. Thank you again!

    Stain removal from fiberglass walls

    I'm about to start the process of stain removal with Polyquat 60 > Ascorbic Acid > Megic Metal. I've read many posts here, I've read the process. My issue is that I have a lot of staining on the walls, pretty much all the way around. But the process mentions dumping it in the pool, close to the...

    Nebula Enclosure Lights Alternative

    Yes, I should have added a link: Homepage. Thank you for pointing out that thread, I'll take a look. In the meantime, if anyone has any other DIY ideas, please share! As far as VOLT goes, I have a kit for landscaping lights (pointing at trees and the house). I never considered this for the pool...

    Nebula Enclosure Lights Alternative

    I've looked all over the forum but there's not much information on this topic. My wife would really like to add some lights around the pool. So far I've found 3 options: - strings of light bulbs draped around the enclosure - hate the look so no - solar - no - Nebula - best choice and there is a...

    Automation for Hayward Equipment...OmniPL?

    I called my pinch a penny again and they confirmed that they are pricing based on MSRP so $2,299 for no SWCG and $2,999 for the one with. They're running 10% off on a bunch of things for a couple of days so that brings it down to $2,070 and $2,700 plus tax. My SWCG is 2 years old so I'd get the...

    Falling grout where fiberglass meets bullnose coping

    Just wanted to report back. I've just redone it with sikaflex polyurethane sealant and it looks pretty good. We'll see how long it lasts. This stuff is pretty sticky. I ended up draining a few inches of water and running painters tape all the way around before caulking. My only other long term...

    Automation for Hayward Equipment...OmniPL?

    Does anyone have any thoughts about this? Or at least know of a good way to find a source for the OmniPL online? Or at least maybe suggest what's a good price for it?

    Automation for Hayward Equipment...OmniPL?

    While I'm trying to get rid of algae after being out of town for a few week and having a neighbor "watch" after my pool, I'm seriously thinking about getting some automation with remote (phone) control. All my equipment is Hayward, listed in my signature. I've stated researching over the last 2...

    Chlorine dropping for no reason - please help

    In between 8pm and 8am I lost exactly 1ppm which I determined by performing the FAS-DPD test in 0.1 increments. My FC dropped from 4 to 3. Ambient temp was 72, no rain last night to account for dilution. And as I mentioned, during the day the SWCG needs to be above 50% to keep up which is...

    I hope you're wrong but I fear you're right :) I just tested it, will test again in the morning and then I will report back. Thank you!

    Chlorine dropping for no reason - please help

    I have a 10k fiberglass pool and live in N Florida. A month ago it was perfectly balanced with all iron staining removed in December. The entire Spring setting my salt cell to 15% kept my FC at the right level. I went out of town for 3 weeks and asked a neighbor, pool owner, to check it. Long...

    Falling grout where fiberglass meets bullnose coping

    I have 2 year old fiberglass pool with 3" bullnose coping going over the edge and down. I do not have any tile, I like this look better. The issue is that some of the grout under the coping is falling off. Yes, I could regrout but I feel like it will have the same fate even if I get the right...

    Which Pool Blaster for fiberglass pool under enclosure?

    Hello everyone! I have a 10k fiberglass pool under a screen enclosure. I don't get leaves or any big/major debris, just fine debris on the smooth bottom and steps. I'd use it 2-3 times per week for 10 minutes. I tried the Ryobi pool vacuum from HD but after replacing/returning 3 in 4 months...

    Struggling with newer fiberglass pool

    Hey guys, I'm going to make one last plea and see if there's someone who can provide some insight into my question. I've spent an unhealthy amount of time looking for answers online and no two opinions are the same.

    Struggling with newer fiberglass pool

    @JJ_Tex, I now understand and thank you for the information. I've done further research into this and I get it now. I'll address the FC issues as you suggested. Can someone help with my questions from the original post?

    Struggling with newer fiberglass pool

    I guess that's another good question. Everything I have read and been told (including San Juan's book) states that the FC should be 1-3 (they actually say 1-2ppm). I have kept it all last summer at a steady 2ppm and I never got algae. So it seems like everything that the manufacturer is...

    Struggling with newer fiberglass pool

    Hello everyone, I have a 1 year old San Juan 10k fiberglass pool that the installer left with metal stains. I was finally able to get rid of most of them over the last 2 weeks and I'd like to get my water balanced to where it needs to be. As of 3 hours ago, here are my levels: FC - 1.8 - I got...

    Aquarite 940 lights not coming on when they should

    Thank you both very much. I'll check the switch and then determine next steps. It's my first pool so there will be some learning in the coming weeks

    Aquarite 940 lights not coming on when they should

    So would this behavior suggest that the no flow switch is bad or that there's a deeper problem? I reached out to the contractor and was told that it will be served under warranty even if a board replacement is needed. Brand new pool and equipment and they want to start replacing parts. So I'm...

    Aquarite 940 lights not coming on when they should

    Without any doubt the flow switch is bad. With the pump off, after a few seconds, the low salt and inspect cell lights come on, but not no flow. Under regular operation, the values shown are: 3400/80/26.5/7.32/50p/-3500/AL-0/r 1.59 E 1.5. If the flow switch was bad out of the box, I'm losing my...

    Aquarite 940 lights not coming on when they should

    JamesW, thank you for your response.The salt cell itself is a TCELL940 and the panel (for lack of a better term) is an AQR940. That was my first guess as well, that the switch was bad and it is stuck on open (thankfully) because the cell is running. But again, the installer initially dumped more...

    Aquarite 940 lights not coming on when they should

    My contractor just finished installing a new 12,000 gallon fiberglass pool along with an enclosure and equipment. Part of the job was an Aquarite 900 and there may be some issues with it. 1) first they added too much salt. The level was 4900, way over the recommended level of up to 3400. I...

    Are there any other opinions? Does anyone have experience with the 2 models that I mentioned, especially as it relates to reliability and support?
