thanks john and jason! i vacuumed the cya last night and will add the borax today.

yes, i forgot to add that due to a major brain freeze and a routine the last week of adding so much bleach, instead of putting the CYA in my skimmer, i put it in front of my returns. so i should vacuum it up and then it's ok to add the borax?

ok, so after a long battle with some mustard algae to start off my season that i hopefully have won (fingers crossed), and finally getting the shock level to hold overnight, i am ready to to take the next step to make sure my pool is ready to go. here are my current levels: FC 13.5 (coming...

hi dave, yes, i should have clarified what i meant instead of just throwing out a comment like that. since i have read that borax has algaestatic properties, it is a helpful aid in algae prevention. in my case, my FC level never dropped below 5 ppm and i still had algae comeback after a few...

just an update, but it looks like things are finally clear! my FC started holding over the weekend, i brought it up to MA shock level one last time, and then let it come down from there. as a precaution, i added some borax to hopefully help prevent this from coming back in the future. thanks...

wow, that is a cool pic up close! i used to be creeped out by them landing on me but now i just watch them when they land on my feet or legs. my mosquito problem was really bad but i got a spray that's made of pyrethrin (sp?). you can buy a product that puts the spray in a lantern and it goes...

hi tanja, i'm in the raleigh area and am curious if you have a lot of mosquitoes near your pool? dragonflies eat mosquitoes, so i always have 10-15 flying around my pool during the day. i'm not sure if it has anything to do with the SWG, but i would love to hear another explanation. either...

so i still lost about 4 ppm overnight so obviously i haven't gotten rid of the algae, but the pool is definitely looking better. i guess this is one of those situations where the FC level i had was just doing enough to fight off the algae, but at some point the algae just blew up. to go from...

ok thanks. since i am already at MA shock level, can i let it get down to regular shock level and keep it there until no overnight FC loss? or will that not do the trick>?

ok, well i got my FC up to 23.5 last night. this morning it dropped down to 17.5. it could be the algae but we also had a thunderstorm in the middle of the night and i found 2 dead mice in the skimmer :( i am gonna keep the MA shock level for a few days, and then let it gradually drift down...

ok, thanks for the advice. i'm gonna give this a shot. maintaining a FC level in the 7.5 range shouldn't be tough since my SWG can usually do that at 40%. the shock level is another story but i'll just have to keep at it. thanks again!

one last question: if it's possible to have mustard algae and not experience overnight FC loss or measurable CCs, how do you know if you've gotten rid of it? thank you again for your help!

i think the biggest reason i am totally confused by this is the lack of chlorine loss at night. also, if it was algae, wouldn't i have combined chloramines? this summer i haven't ever had more than 0.5 during any chlorine test...

hmm, the pics didn't load.... let me try this: http://s966.photobucket.com/albums/ae14 ... =slideshow

ok, so i need to revisit my issue. i thought i got rid of whatever this was but it is back and "better" than ever. i ran the aquabot all weekend and also shocked to MA level. my current levels are: FC 17 CC 0 TA 70 ph 7.5 CYA 50-60 i haven't had overnight FC loss although i didn't test...

that's what i thought about the FC holding overnight too, that's why i'm stumped. when i get home i'll take a pic and post it. i run the pump anywhere from 10-12 hours a day (usually from 9 am-8 pm) with the SWG set on 20% (sometimes 40% if it's really sunny or a lot of people swimming) and...

so i am completely stumped at this point: i had algae at the beginning of the season because of a broken pump, got this fixed and followed the algae advice in pool school, and got rid of it (or so i thought). the last few days, i have seen what HAS to be algae growing on the walls, especially...

thanks waterbear! i obviously was confused. the next time i'm at the store i will look to see what it is.

thanks waterbear! i'm pretty sure i added enough to get the CYA up to 80, but i will test soon. how long does it usually take for the powder to dissolve? also, have you heard of a ph reducing product designed specifically for swg? i'll have to see what the exact ingredients are, but i wanted...

right around there. the range is something like 3200-3600. last summer i kept it right around 3400 with no problems. i will check the FC tonight and if it's on the low side, i'll turn off the SWG until i can get my CYA level up. thanks!

i actually just started up the swg now that i have my FC stable and holding. my salt reading was 3400 ppm but i am ordering some new salt strips since the ones i have are old and right at the exp date. thanks for your help!

hi everyone, i tried to find the answer to my question on the stickies first, but i wasn't quite sure if i found the answer, so i figured i'd go to the source. i opened my pool last weekend but the pump was shot, so i had to order a new one. long story short, algae started to develop in my...

well i've been checking it every other day and it seems to be consistent now.

yes i did. thanks again.

thanks guys for the advice. i checked the FC this morning and it's the same from the night before. one other quick question: when i did the ph test with the phenol drops, the initial reading was low, around 6.8. after about a minute though, it read 7.6. is this reading accurate or should i...

i have been lurking on the board for a while and first wanted to say thank you for all the incredible info. now to my questions: this is our 2nd summer with the pool but we had to get a new liner put in and also added a swg. as soon as it was done around memorial day, we went out of town for...
