So the milky white is dead algae. That doesn't mean that you are finished with the SLAM, but it's a good sign that you are on the right track. The continued chlorine is to make sure that all the algae is dead. The milky white will get filtered out and or settle to the bottom but it could take...

So balancing to keep the CSI in the range is the key?

I just ordered a RJ45+ after years of liquid, pucks, and cal-hypo. I read the opening on SWG chemicals and see that 60-80TA is important. I'm currently at 140TA, 7.0pH (and just started airating to bring pH up), 50 CYA, 160CH. I'm going heavy on the pucks right now to bring the CYA up to 80...

I'm thinking of adding a robot due to the paper berch tree seed pods in the spring and leaves all summer long. (along with Japanese maple and weeping cherry) I'm zeroing in on the Doheny's Discovery. Any words of wisdom before I pull the trigger?

Well I ran the pump for a few hours, added 8lbs alki plus to get started last night. This evening I have: FC: 23 pH: 7.8 TA: 80 CA: 70 CYA: 30 What just happened?

CYA was 50 when I closed, but about half the water has been removed and replaced with rain/snow water over the winter, so I was expecting about 30 CYA. Interesting CYA eating bacteria.

Ahh, back to the basics. Thanks for the reminder. when I winterized the pool everything was perfect. Now? FC: 0 CC: 0 pH 7.5 TA: 20 CA: 20 CYA: 0 So, I'm going to get the pump running, bring up the TA, then use some triclor pucks to bring the CYA up and pH down (assuming the Alki plus will...

I think the bleach I got is old.. I added 12 gallons and have no FC 10 minutes after I added it. The green was only a little growing in the steps. The water was and is clear....

My pool is still closed for the winter with a mesh cover. I went to pump some water out and noticed some green growing on the steps. No FC... Water is 52F. I started to SLAM, but wanted to make sure there isn't something I'm missing. The quick chlorine test should work at 52F correct?

Thanks for the comments. I have an inline puck feeder, but I didn't think It would produce enough to finish the slam while I was away for the weekend.....I also didn't want to pour in massive ppm of liquid. I chose the lesser of the evils I had available. Definitely has me thinking about the...

Update, Went away for the 4th for a few days so I put 8 tri chlor pucks in the skimmer basket out of necessity. (brought CYA up to 50-60 range) Came back and the pool was crystal clear and still at slam level. I am now back to 1/2 gal 12.5% (3ppm) usage per day. So yes, in retrospect the slam...

Thanks for the feedback. That is probably what started it. I had two of the trees taking out this spring. Still have one left. I will make a note to do a better job cleaning those up next year.

This is an odd one. Verified the cya at 35-40 yesterday. Fresh tft refill this spring so chemicals should be good. I have been checking fc level before I add liquid bleach and after 1hour. Then again at 10:00pm and 6:00 am to get the oclt. It has been 0 to 1 ppm loss. So I have kept the slam...

Pool got away from me in a rainstorm and river birch dumping seeds in the pool. Started the SLAM as it was starting to get cloudy and using twice as much chlorine with nothing left at the end of the day.. Now 2 weeks later I'm still at slam level, been passing the OCLT since day 3 but the pool...

Re: SLAM - Now What?? So you need to leave the pump on to filter out all the dead algae. The dead cannot come back to life. It will slowly sink to the bottom for you to vacuum up. May take a week or two withe the pump running 24/7 to clear up.

Wow, I didn't realize dichlor had that much CYA! No wonder I've had troubles with too much CYA in the past. I see that in the calculator now. I have a 10 lb bucket left over from my pre-TFP days so I'll do that and pH control and we'll be set. Thanks everyone!

Thanks JoyfulNoise, I didn't think of that! I like the sock idea YippeeSkippy!

I got a new liner in the fall and got the water cleaned up, pH adjusted, algaecide 60 in and closed it up and put the mesh safety cover on. So now it's a month from opening and it's apparent that I don't have any CYA in the pool due to the new water. I added chlorine and it was gone in a week...

The light of day reveals that the alge is dying! Starting to flip to the white cloudy blue!

We had a big rain storm last night. FC 34 this morning.

I have a stain on the liner that comes off super easy when touched with vitamin c. Added metal out and a bunch of rust fell out of the water and landed on the bottom. Water is slightly cloudy green. Cannot see the bottom of the deep end. This all started with 2 months of 6.8 ph. When I...

6 hours later: FC 44...... So in 6 hours the FC hasn't moved from the initial slam. Water looks the same...... Doesn't seem like it should have held at the calculated first dose if there was an algae problem. pool is still light green and lightly cloudy. The good news is that the CYA is in...

Drained and replaced water with city water. About 4,000 by adding water in the deep end while pumping out of the shallow end followed by 10,000 refill. (total volume of pool is estimated at 20,000) water added as measured by the city water meter. Shot home at lunch to turn the water off. TA...

For some reason my signature only shows in the first post. I'll look for a setting.

Thanks all for helping me see the alge problem! Pumping the pool down now. I need to ban trichlor from my pool! Swg or liquid is in my future.

No. I've lowered to 12" in shallow end successfully several times. That will get about 40% of the water by my math. So will have to do that twice to make some headway.

Cya 160 Fc 6.5 - - - Updated - - - So do I slam first or dilute first?

Cya is probably a little higher. I should try diluting and run the test again. Chlorine seems to be holding. I haven't been shocking daily. I should probably break out the big kit and make sure. I do have non copper algecide 60 in the pool.

I let my pH slide low this year down to 6.8. It's been slowly sliding since I opened 2 months ago. I finally brought the ph back up to 7.2+ and the liner got brown stained, the water got a little cloudy and has a green tint. Fc 8 Cya 100 Ta 100 Ca 140 Ph 7.2+ Ascorbic acid test takes the...

Thanks for the help! I found the correct skimmer doors, big improvement! I also got a 42" leaf rake, lots faster!
