For anyone wanting to successfully use baquacil....

I think I may have found the best solution to controlling the usual issues that baqua pools are plagued with- the white water mold, pink slime, cloudy water, inability to hold a peroxide reading, etc. - I've started doing the following: 1) test regularly for peroxide and biguanide and add enough to keep the levels up 2) add one container of "Ahhsome" pool water clarifier monthly 3) Use 2 tablets (or whatever depending on how many gallons) of Aqua Finesse Pool Water Care Tablets in the skimmer weekly 4) CDX once weekly, along with algaecide once a week I have had very few problems, and indeed posted a picture here last season that some people found rather impressive for a baquacil pool in terms of water clarity. Granted, the system I'm using is expensive!!! So if money is the key issue, then this is not the way to go for you. At this point, as much as I've ranted on this forum about being ready to go back to chlorine (and yet preferring not to), I'm content to stay with what I'm doing. Just my two cents...

Forgot to mention that I keep detailed notes on everything - results of all tests, when which products are added, etc. - using two spreadsheets that I created on my laptop. I know now that in years past I was relying on a fairly fixed pattern (or guesstimating) as to when to add things and how much - especially peroxide. Doesn't work. I buy enough peroxide to last for (hopefully) the entire season and ...yeah...it's probably about 6-7 boxes of 4 gallons each. If I need more, then so be it. Once the water temp gets into the mid-80s, that's when I really have to be at the top of my game with regards to frequent testing and adding. Also, we are literally surrounded by actively-worked farm fields - which probably makes running a pool here even more difficult no matter what system I'd be using. I've come to the conclusion that IF I'm going to continue with baquacil, I need to spend whatever it takes and not try to cut corners with adding B and C.

It’s good that you have found a way to make bianguinide work for you, since it is your preferred sanitizer. I also appreciate your openness about the cost of using it effectively, and the amount of attention it requires to be successful. It is a sanitation system that is not very forgiving once mistakes are made that cause water quality to decline. This is all good information to have when making a choice between chlorine and bianguinide for sanitation. Thank you for sharing your insights with us.

zea3...thanks. I should have added one more item that is probably an important one - last summer I decided to buy another extra set of DE grids (not sure why I didn't do this years ago). It seems to make some sense that, when the grids are taken out and hosed off - then when they are put back in - whatever residual unwanted stuff is still in there will soon enough start creating problems again along with quickly increasing pressure, then followed by another round of taking apart the filter. Ideally, the set of grids not being used at the time should be chemically cleaned while out of use, but I haven't gotten that over-zealous yet :) However, it seems that the grids that are allowed to dry out throughly (thereby alternating grids) provide for longer filter cycles. It just seems a bit silly to have to take the pool out of service for a day or two while the sole set of grids is soaking in cleaning solution (I use a large bucket). By having an extra set, this is not an issue.

Thanks anthonypool89. I am a new pool owner (open ~3 weeks) embarking on the Baquacil journey and hearing some positive comments and practical advice is welcome. My water is currently very clear but my and my local pool store’s testing shows chemical levels are consistently low. Trying my best to learn what chemicals and cadence to adhere to. So far they’ve only recommended I add Oxidizer and Sanitizer/Algistat (1.5G and 0.5G each last week and this week). I’ll look into your regimen as I progress.

I do have two questions. Are you relying on just the test strips for testing? And how often do you test (once weekly)?

PD.....I gave up on test strips. Too many people here told me they're just not that reliable. And I gave up on pool store testing. I have two Taylor kits- one I use for pH, CH, and TA - and then the other one is only to test for baquacil and peroxide levels. Unfortunately, the baquacil side of the kit does not work due to interference by quats in certain chemicals, including the reagent that came with the kit. Long story that is dealt withhere in another thread. Short explanation - it makes it impossible to get the correct color change. So then, I wound up buying yet another kit that does just pH and baquacil. That seems to work pretty well since the color change is not in shades of blue (the blue color is where the quat interference takes place). Still, it's a bit hard to arrive at exact levels by looking at the color comparisons even with t his other kit. I admit to doing a bit of guesstimating. As to frequency of testing, I do it every few days and record all the results.

Hope some of that helps. Feel free to ask as many questions as you like. I'll answer them all if I can!! It has indeed been a "long strange trip", to borrow from the Grateful Dead 😏 Best of luck. I hope you can make it work for you. I must say up front that it is NOT cheap to maintain a baquacil pool if you want to do the most to avoid the issues associated with the usual white water mold and pink slime. I've been doing pretty well, but use quite a few different products. A few that worked quite well have been disappointed over the years, so I've had to research to find new ones. Another thing you will need to be prepared to deal with is more frequent filter cleanings - at least with DE - then is undoubtedly the case with chlorine. If you have a sand filter, you're probably in better shape than I since a friend of mine also uses baquacil - only with sand - and doesn't have to backwash, etc. anywhere near as often as I do. It gets a bit tiresome after awhile and, very honestly, as much as I love the swimming season, by the time October rolls around I'm relieved when I finally get to turn that breaker off and realize I have about 7 months of not having to worry about what the pressure is just about every day. All that being said, there are times when I get exceptionally long filter cycles -4-5 weeks on occasion. It's great when that happens, but I've reconciled myself to the inevitable fact that the pool dictates the schedule, not I.
