    Vinyl liner - terminology

    Thanks Dave. The easiest solution would be to go to one of the aforementioned pool companies and buy the vinyl there. What I was hoping to do though, was apply the BBB thinking to a pool liner - accumulate enough knowledge about "vinyl liners" (i.e know exactly how to tell vinyl from other...

    Vinyl liner - terminology

    Hi All. As expected - due to a job poorly done - my fiberglass pool paint is coming off and making my water milky white, less than two years after resurfacing. Since I do not intend to go through resurfacing again, I was thinking about using a liner. At the time I got an offer from a local...

    Liquidator allowing air in when pump is off

    Hi All, I have been using the LQ (with the 3/8) for a year now and love it. That said, I have been ignoring an issue with it and would appreciate your help fixing it. Since my LQ is higher than my IG pool, when the pump turns off water flows slowly from the LQ into the pool (via the outlet)...

    DIY solar heating

    Thanks again Leebo. I just had a look at the link you've posted and its exactly the kind of "design" I am using, although my panel size and density are nowhere close to it (Yet! :mrgreen: )

    DIY solar heating

    I'm sorry Leebo - did not mean to laugh at your misfortune. Its this media; one never can gauge the entire content from text alone. For some reason I found it funny - probably because I perceived it as a humorous cynical remark as to how the heater stopped working, and my affinity to...

    Using DE with a sand filter

    Thanks guys. I've done some more reading on the subject. I am definitely not going to use DE unless I have a way of removing it safely. I still have no clue as to how I can do this, but I would like to share what I have read about DE, and ask that you be careful when using it. Apparently there...

    DIY solar heating

    Leebo, I don't know why, but that was hilarious :lol: Thanks a lot for your help, linen, Leebo. With your feedback and my successful PoC, I am now on a quest for finding the best kinds of plastic for the job. I even found a company that makes polymers that are as conductive as aluminum (for...

    DIY solar heating

    I know commercial panels would be far superior to anything I would build, but as I do in other areas and hobbies of mine - I love taking on projects not just for the sake of the end result, but for the fun and experience I get when doing things from scratch myself :-D So, off I went and...

    DIY solar heating

    Hi all, Since I live in a very hot and sunny area, a part of my recently completed project involved placing a shading net over the pool. Funnily enough the kids complain the water's too cold now. Never thought that could happen in our parts... :shock: So, I was thinking of starting a new...

    Using DE with a sand filter

    Hi All, Wasn't sure where to post this.... Basically everything is running smoothly with my pool, and the water is "fine". The only problem I am trying to control now is cloudiness that is the result of chalking (paint dust coming off into the water). I am keeping things under control by...

    Using Trichlor to raise CYA

    Wow! that spreadsheet made my head spin :-D Can't wait to delve into it when I get back home (though it seems I will be in over my head pretty soon...) Richard, I hope you don't mind me asking but I'm really curious - Is your knowledge of chemistry the result of a hobby or of...

    Using Trichlor to raise CYA

    Thanks loop_pea - I don't recall ever using the "effect of adding chemicals" section of the calculator. Works like a charm :goodjob:

    Using Trichlor to raise CYA

    Hi Jason, Richard, I am not sure who the owner of "the pool calculator" is, but I thought that if anyone can help it's probably you. Since I use Trichlor to reach the stabilization of the pool, I think it would be great if the section on CYA also contained the very useful detail that CYA is...

    Interesting... I didn't know that. Thanks! No micromanaging necessary after all :wink:

    pH levels and FC

    Thanks guys - I get it :P In hopes I will keep this going all summer... The pics will have to wait a while as my pool area is a mess right now; I am working on replacing my suction side pipe and some of the tiles are out, pieces of grass hacked out, etc... On the up side, I did finish a...

    pH levels and FC

    Hi All, I have the following parameters established: 1. Shading net over the entire pool area 2. Opaque pool cover (at night and most of the time the pool is not in use) 3. A working Liquidator 4. 2 x 200gr Trichlor pucks already dissolved (approx. 15 ppm CYA according to the pool calculator)...

    Fiberglass pool resurfacing issue

    Another update: I keep posting on this thread as it might be valuable to other people in a similar situation. My pool has been operational for 1-2 weeks now, and is doing fine. Dealing with the chalking is not too hard although it is definitely an aesthetic issue. First, I do believe the...

    Replacing the suction side pipe

    That's why I made the drawing - I knew the 135 would be a confusing description. I guess then its a matter of convenience now. Thanks, Yoav.

    Replacing the suction side pipe

    Hello All, I am about to replace my suction side pipe using rigid PVC, crossing the back yard from skimmer to pump and in effect making a 180 deg. turn. I have two possible ways of doing it and was wondering if there is a difference. The upside of the second option is less digging... but I...

    FAS/DPD reagent

    Thanks James, That sure clears it up for LaMotte. I wonder if that holds for the Taylor kits as well...

    FAS/DPD reagent

    Thanks Freelancer. After some experience with electronic testing equipment, I decided I'd rather use simple, reproducible, no-maintenance testing devices. I hope that in the ColorQ case, their electronics are off, which would mean I could still use their other simpler kits. Unfortunately...

    FAS/DPD reagent

    Apparently there is a distributor for LaMott test kits in Israel (finally!), and I am looking into it. I was wondering if anyone here used their kits (not the electronic, ColorQ ones) and can provide feedback. What I was not sure about was the FAS/DPD reagent. They seem to refer to a DPD #1...

    Installed The Liquidator

    Hi All. I've installed The Liquidator and I'm as happy as can be :whoot: I've seen many posts on this topic but thought I'd share my experience, just in case it may help someone else down the line. All in all, it was easy to install. One point worth mentioning: After replacing the 1/4"...

    Fiberglass pool resurfacing issue

    An update: I managed to get in touch with an Akzonobel representative (the manufacturer of the paint) who basically said the following: 1. Epoxy paints are not normally used for outdoor pools (as opposed to rubber based paints). The "Bar Rust 233" used in my pool is designed for internal...

    Fiberglass pool resurfacing issue

    Hi Scott. I really appreciate your help with this. Aside from this forum, I have not found a single source of info which can tell me what it is I am seeing. After you've explained what the resin and cobalting is, I decided I would fix it myself with the aid of my neighbour who volunteered to...

    Fiberglass pool resurfacing issue

    Hi again. Has anyone seen the video and can comment on it? Jason, I went over the thread and realized that I may have misunderstood you - when you wrote "the chlorine levels will break down the paint debris" I thought you meant that the chlorine is responsible for the paint coming off. I think...

    Fiberglass pool resurfacing issue

    Hi Scott, Jason, I don't know if you are still following this thread... A picture is worth a thousand words, so I uploaded a short video that shows: 1. What the ooze looks like 2. What happens when I wipe the surface with a wet cloth. http://www.youtube.com/watch?v=k89JHmtTcQo I was...

    Fiberglass pool resurfacing issue

    He claimed to use Devoe Bar-Rust 233. The spec says its suitable for potable water. I also contacted Devoe who said its OK for pools. No. Its color was faded and uneven, and some small scale cracking and peeling. The contractor said he found several places that had holes which he patched with...

    Fiberglass pool resurfacing issue

    Hi Scott, thanks for responding. After reading your post I am not sure how to proceed. I am quite certain that everything going on is the result of the resurfacing job - nothing of the sort was present before it was done. BEGIN :rant: I have many reasons to believe that the contractor that...
