I posted about mustard algae a few weeks ago... thought I got rid of it , But whatever it is it's back ! Because it's the end of pool season here in Montreal, I kind of like the pool go for the past week and a half ( we were also away on vacation for a week ). Right now it's a greenish...

Hmmm but I did slam properly!? what does it mean to not lose 1pm overnight? Does that mean if it's 12 at slam level then it has to be no less than 11 by next morning? That's the part I'm unsure about...

Thank you I couldn't find the mustard algae shock instructions. I read through your link, and it says that pollen is usually at the bottom of the pool, but tyebpatches were on the side creases of the pool as well (where the liners meet)... I hope you're right and it's not Mustard algae...

Hi, I think i have mustard Algae...patches of yellow on bottom of pool, when brushed it's like powder... all my levels are within range, my SLAM level is 14 and did it the other night, by morning FC was 7. Brought it back to slam level in the am so it can kill all remaining residue, brushed...

I've had a yellowish residue on the bottom of my pool, it's in patches all over...I tried to vacuum it and it's back the next day. Is it the start of an algae outbreak? I've never had one so need to ask! If so, should I slam tonight ? Also after vaumming I made sure to backwash and rinse in...

Thaaaank you, now it all makes sense! Will try =)

OK so when you do this, there's no basket to protect main line, correct? Also forgive me for not fully understanding, but how do you put the main vacuum line directly in the hole WITH the adapter? My adapter makes it so it's one hole, unless you have a mini adapter plate (only thing I can picture )

Hi richard I don't quite understand what you mean!? I do use a plate. There are two holes in my skimmer, the right one is supposed to be main line and left one is main drain. Both are unplugged and plate is used for vacuuming... Can you clarify what you mean by plugging the hole? Is that...

I posted this issue before but it's still not resolved. When I vacuum to filter I get almost no suction. When I vacuum on WASTE I get crazy suction. Agreed that this indicates an issue with my filter or pump ...we cleaned out our sand filter as suggested with a hose for hours. My pump basket...

Tested my CYA a couple weeks ago was up to 35 (had an issue with zero in pool when I opened) so with the help of this board I finally raised level. From my understanding the CYA level doesn't really drop!? Using a TAYLOR KIT 2006c was steady for a while then the sudden loss of chlorine overnight...

Will do NOW!! Any idea what could cause such a quick decline of choline overnight with cold weather (14 c at night) and rain? Was it low PH?

My pool has been crystal clear and balanced for a steady 6 weeks, but this am I woke up to a cloudy pool. Last night I had tested total FC was 4 and zero CC...this am there is almost zero chlorine in there and PH was low (7.1). It was a coolish night, no warm weather lately, but lots of rain...

So owning a pool is new to us, and I know the previous owners mentioned that there was a small patch job done in the liner of our pool (no idea when but yes pool is 2002 build). Had a bunch of family over to swim today, and of course my 8 year old nephew comes to see me with his goggles and...

Thanks!

Nothing was happening it was staying clear no matter how many drops I added if anything. I did it a second time just now and now it turned blue at 16 drops so it's at 160. Do I leave it there? Also for PH test with Taylor kit I find the results are different if interpreted immediately and after...

Taylor 2006

I couldn't get a proper reading for my CH with my home test kit, so I'll be heDing to the pool store unfortunately. I remember it showing up as an issue during pool opening, but the store specifically told me not to adjust (since it wasn't too off) because I just purchased a heat pump and it...

Since I got my Taylor kit I haven't been back to my local pool store, my pool looks FAB and I have saved so much $$$! THANK YOU ALL! Have a question about adding chlorine & PH reading: last night I had a lowish reading and just wanted to raise back to 5 since we have some hot weather (finally)...

Thanks Richard I'll try first thing in the am and see if things improve. That makes totally sense actually! I'm reading through the link you posted, never knew I had to rinse after backwash. Will follow the steps. Also How long is backwash supppsed to be? Unfortunately I don't have A...

Hi all! I'm noticing that when I vacuum on filter there is almost no pressure at all. The only way I can get suction is by putting my filter on Waste and vacuuming as quickly as I can. Is there anything I should be checking to maximize suction? I do wish I could vacuum on filter more...

Thanks to all! Just to update my CC is now zero and I'm holding FC in my pool!!!!!!! I can't tell you how happy & thankful I am for this site. My pool store had me spend so much money and go back and forth testing water...I'm 8 months pregnant and it wasn't easy let me tell you! The solution...

Ok perfect Thank you! And I noticed the only thing "off" was CC reading at 1, Iif I understood correctly in Pool School, it has to be 0.5 or lower so I should continue to maintain an FC of 12 until the CC becomes zero? Does that make sense?

I just got my test kit this week TAYLOR 2006, I noticed that it takes a lot of drops to test the FC hopefully I don't run out if I do it every day ?! Can you buy the drops separately? I ordered the kit online (it was hard to find for shipping to Canada...and expensive!!!)..but I am hoping I can...

I did my test reading today in the am and everything was within range!!! cYa 34 But FC was 11.5, is that even possible?! I'm so happy to have chlorine in my pool it's surreal :)) I did liquid bleach 10% 5L 1.5 jugs (according to pool math) to get it to 12 range and it was still high this am...

Thank you! It was at zero to begin with so I'll slam accordingly! I did vacuum what I could see on waste since it was a small amount... my vacuum doesn't work well on filter very little suction & wanted to be sure!

Hey everyone! I used Pool Math (and had help by others) to know how much Cya to add to my pool. Started process yesterday (sock in front of skimmer) and then finished this am with the rest...I noticed that on the bottle I got from a local hardware store it says to sprinkle on pool surface. So...

By the way is CYA (stab) something I have to add regularly like chlorine? Or once I add it will it stay in my pool?! I finally figured out pool math:) just want to understand the concept before I put things in my pool!

The goal is to do it myself, I just joined a few days ago and I am new to the pool world completely! I ordered my test kit and I am constantly reading up on everything, it may seem simple to you guys but it's a whole new world for me and I am taking it all in. I appreciate the responses and I...

Thanks! The pool store told me its metals, minerals, then copper...I've spent SO MUCH MONEY! I will go to Canadian tire and buy stabilizer and put in the pool. I read Pool school 10 times, I understand now but what I can't figure out is how to use the pool math calculator. When I put my values...
