This is going to be a long post. So for the TLDR crew, here it is in a nut shell: How do you guys in the south, who: 1. Still sanitize with "pucks" and 2. Don't close their pool for the winter manage to not send their CYA levels to absurd levels? Now for the detailed version: A buddy of mine...

I know on the surface the answer to this question seems quite obvious. But I am following another member's thread regarding Mustard Algae coming back year after year and it made me consider the question: If I have hidden algae when I close the pool for the season is it possible for algae (be...

JamesW - Quoting you from another thread here because I didn't want to hijack that one. Can you explain to me all three sensors? I am wondering if maybe I have an older version of Aqua Logic different than what you are describing. When my digital panel scrolls through the various readings...

The ounce/pound/gallon/boxes/by weight/by volume conversions in the Pool Math is killing me. Everything has a different unit of volume. I think I got it, but thought I would ask the question anyway. Is this a correct equation? 55lb Bucket of granular Boric Acid from Duda = 18 Boxes* Mule...

I'll gear this question toward the northeast guys because I know what our pollen season is like. But if other areas of the country experience seasonal pollen feel free to chime in.... I've always been in the habit of just using skimmer socks early in the season when the tree pollen is high...

I don't know how I lived without this test for so long. You may recall from some of my comments in other threads that I am running my pool with a higher CYA than I have in the past. Hence I need to run a higher FC level as per the Cl/CYA chart. I have been slowly playing with my SWG settings...

Diluted muriatic acid I guess is the cheapest. But is it the safest? Cells are expensive and I would rather spend a little more to do it right and safe as opposed to doing it cheap and possibly causing damage. Is this stuff a complete waste of money? Amazon.com : BioGuard SaltScapes - Cell...

I know and understand that the TF-100 is the preferred and most recommended kit around these parts. But buying one and tossing what I currently have in the garbage seems wasteful. So what I am looking to do is buy individually what my kit doesn't have and what I am currently running low on. I...

With these automated systems, when you set your %'age setting for your SWG what exactly is happening? Let's use a 50% setting example: If I am running my pump for 8 hours does this mean that the SWG is producing chlorine for 4 hours? Or does it mean it produces the entire 8 hour run, but only...

As my last step in balancing my pool this season, I need to add 25 lbs of Calcium. How will this effect other chemistry? Is it going to do anything to the pH? Or anything I need to be aware of?

So I am playing with the pool calculator. I currently have 2 windows open side by side on my computer: Window 1: Pool School - Water Balance for SWGs Window 2: http://www.troublefreepool.com/calc.html (with my numbers) I took all recommended numbers from Water balance for SWGs and plugged in...

Joy, thanks for the detailed response and that link. Just a few follow ups.. This statement...... is simply not true unless you run your pump 24 hrs a day with the cell set to 100%. See my example above. (Run time 8 hours at 70% = 5.6 hours a day.) Now I don't know if that means the first...

Both reagents are "Phenol Red". But I think they are different products. Possibly for different kits. My kit (don't flame me) is a K-2005. Which contains the R-0014. I was running low last year so I ordered a replacement vial. I never realized until just last night that what I ordered was...

When I test, I tend to test for a range. And that is typically good enough for me. But this forum recently told me to get my pH from 80 down to 60 to help control the fast rise of pH. My question is this, when I start adding the reagent to turn the color of the solution from green to red...

This may be long but want to give all pertinent info, so try to bare with me: After opening my pool this season, I quickly discovered that my Salt cell has ran it's life expectancy. BUT before I knew it was bad, the salt was reading too low according to the automated board for the SWG to work...

It's a Hayward Goldline Aqua Logic AQL-PS-8 system with the T-Cell-15 cell. Question is: Does reading a lower salt level on the computer than what is actually in the pool indicative of a cell going bad or does it just die in one shot? I can still make Chlorine, but I had to raise the salt...

My pool consists of the main body of pool water along with a spillover spa. Both Spa and pool share the same equipment and is the same body of water. The problem I am experiencing is a surging of intermittent air coming out of the returns. When in "pool" mode it is barely noticeable, just a...

I was reading through the Pool School Definitions Page. Pool School - Definitions and Abbreviations I came across this comment under the definition of Dichlor: I don't use dichlor, nor do I care about it. But what I do care about is why does that comment suggest that if you have a cartridge...

CYA - Being a SWG user, I know I need to keep CYA on the high side. I am shocked year after year, how low it gets from dropping a few inches of the water level for the winter. But it does. I need to bring it up from 30 to about 75. I will need about 15 lbs. This can get expensive. Any...

First off let me state pool is always crystal clear. Visually it is great. Minimal scale which I will knock down with a pumice stone once I get in the pool. But these darn readings! I am almost at a point of saying heck with it and if the water looks good just let it be. This pool is...

I am thinking of adding an automated pH adjuster after 10 years of constantly dealing with the never ending cycle of pH rises, add acid, pH rises, add acid.... All season long. The question is which one. I want it to be the most seamless plug and play into my existing system. Here are the...

In an attempt to knock out a mild stain on the floor of my deep end, I think I have caused larger issues. It was recomended to me to use Sparkle Conquest to knock out the stain. Pool has always been crystal clear with no signs of algae. All I ever do is adjust my SWG higher when we in the...

Why would one ever use a copper (or metal) based Algaecide? Don't we want to keep metals OUT of the pool? What's the advantage?

I have read the Ascorbic Acid article in Pool School and I have also read the long 7 page thread (which is now closed) laying out the steps to perform this treatment. So no need to direct me there. My confusion is: When I lower the FC level to near 0 so the Ascorbic acid doesn't get eaten...

When you have a question always start your own thread rather than hijack. Butterfly Where do you guys buy Cyanuric acid? I recently bought 2 six lb containers at local pool store for $36 per container. It was BioGuard which I believe to be a quality product but surely I should be able to find...

I am new to this forum, but certainly not new to pool care. I have to say I have never seen so much attention to maintaining different Cl levels based upon one's CYA level. I am not really sure what I am missing, but these charts seem outrageous to me. I mean there are areas of the chart that...

I have a Dolphin Robot with the very heavy (thick) bag. They advertise that running this unit is like having a separate DE filter on your pool because this bag allows nothing to get through. I was wondering if you guys think I can actually be removing chemicals from the pool that started out...

I joined this forum to learn about borates. I have always had a problem with pH rise. Pool has been in since 2006. So I took the first step last night. dumped 11 boxes of 20 Mule Team and 3.5 gallons muriatic acid in. That doesn't even get me half way for my size pool. will add more by the...
