Thanks I'll definitely keep an eye on it. I've already checked the guage a bunch of times today. About that Hayward wand, is it just like a high pressure attachment for the hose, or does it slide over the fingers or something? My only gripe with the DE is not having a good place to drain it...

Well see I guess. I usually go all summer without needing to backwash. Pressure never rises. I did a good job cleaning, used some spray that you let sit and rinse off. The fingers were bright white when finished.

So I think I have it figured out... 1lb of DE is about 6 cups. I put just over 6 cups of cellulose in the filter. 6 cups would roughly fill a 1lb coffee can like you suggested, just as 6 cups of DE would (or 6 cups of anything) 1/8th of 6 is .75 So I put in just a little more than that...

My filter is only 27sq ft. So your saying a coffee can fit 60 SQ ft... So then half a coffee can for 27?

Hmm. How do I figure out the volume? Also how would I know if there's not enough cellulose in the filter? For what it's worth when I first moved in I was using probably half of the correct amount of DE and never had problem. Was using the wrong size scoop and less total scoops.

I'm just confused about the dosage. Bag says 6 cups for 24 sq ft. My filter is about 27 sq ft. That's not my issue though. According to the chart on the bag you only need 1lb of DE per 10 sqft. So a 27 sqft filter would be only 2.7lb of DE. the label on my filter says to use 6lbs of DE. So I'm...

I have the siphon style pump as well. Have you tried the bucket lid idea? I never considered that it was sucking water through the cover, rather that the weight of the water was forcing the cover down and water was seeping through. I don't understand how the lid will prevent it.

My pool is 18 round and was thinking of using 2 4x8 pillows this year and not draining below skimmer. The idea is to keep water from pooling on and subsequently leaching through the cover. I bought a brand new (not cheap) solid cover last year and water still leached through. So I was pumping...

I cleaned it when I closed it on October, used muriatic acid on the grid. When I opened the pool the water was clear, maybe slightly cloudy. Haven't felt the need to clean the filter, no pressure rise, not a lot of debris in the pool. Only vacuumed a handful of times, each time very small...

I have this filter, nowhere can I find a reason to backwash unless the pressure keeps rising after bumping then they recommend replacing the DE. My filter pressure has never risen more than just a couple psi over an entire season. Never even have to bump according to the directions on the...

So I wanted to update, pools been clean, water is clear, keeping my FC on the upper end of my target FC LEVEL (pool math says 4-8) and it hasn't dropped lower than 5.5 since the slam. Lose about 2.5-3ppm over the course of a hot sunny day in full sun. I still get very small specks on the liner...

How do I do that lol? I always just sprinkled it in around the pool like the dichlor faery. Just started BBB this season.

95

Thanks. Is there any reason I shouldn't just use the dichlor? Other than maybe pH decrease? My pH is 7.4 so it shouldn't be an issue, I'll just turn the jet up to the surface to aerate.

I was going by the directions on the bag. Says to mix in warm water and add skimmer.

Been filling my pool a lot last couple weeks, it's been dry and windy. Cya is down to around 30 but I think less than 30. I'd like to bump it up 10ppm . I have 1lb of 99% dichlor and I also have dry stabilizer. Dichlor would be easier to just add it to the pool no pre mixing. Pool is 7600...

Passed OCLT finally. Just .5ppm FC loss, CC at zero. I need to add water, had a lot of evaporation this week. Haven't had much rain. Had to take the weir door off last night, was laying too flat causing air bubbles to get in the pump.

Yea I'm doing another day, added chlorine 2x already, gonna do one more before work and then again after work. Then I guess I have to bring it up to mustard algea shock level for one day.

I'm going on day 5 of SLAM and still lost 1.5ppm over night. (20ppm - 18.5ppm) Tested at 11.30pm and this morning at 7am. Should I test earlier like before the sun comes up? (Sun was partially cloudy and low in the sky but I don't have any trees blocking it. I wouldn't consider that direct...

I actually used cal hypo the first day because like I said I was in a rush, and this is all new to me. I just saw the option to slam with cal hypo on pool math and thought it would be fine. After that first shock I did switch to liquid. Before SLAM PH 7.8 TA 85 Water is and was always clear...

So my pH was 7.8 before starting slam Ave I neglected to lower it. I was in a bit if a rush to get it started before I left home and I didn't realize until almost 2 days later. Would it hurt to throw in some dry acid to bring it down? I know I can't test it now because I'm at shock levels and...

Such a pain in the Rear. It's tempting to just use a phosphate remover, both processes are annoying. I just took my pool ladder out and will clean it again before returning it to the pool. I didn't think to sanitize the kids swim jumpers either before they used them this year. That's on me. And...

Any updates? I had this last year and thought I was in the clear this year but it's returned this week. This is my first year using the BBB method. Last year I used an algecide when closing the pool that got rid of it finally.

Thanks you've been very helpful. I'm actually starting to think I maybe just have pollen that's settled to the bottom and not algea at all based on stove other threads I've seen on here. I really need to spend some more time on here looking around. It's collecting along creases and winkles in...

Only thing is I've been going off the pool store test for cya. But I suspect that it's lower than their reading. I don't really like the cya test, it's hard to get a good reading IMO. I feel like I can always see the dot if I try. So I'm going to treat the pool as if the cya is 50ppm. That way...

Thanks, I guess there was a few things I didn't fully understand, and I didn't think algea would start to grow that quickly at 3-3.5 ppm. Just gotta keep the chlorine a little higher, thanks for the tips..

Thanks, I'm just not sure how it happened. I've been testing everyday. It was very hot this week and my pool is full sun all day, so the FC did drop to arround 3.5ppm one day. Recommended FC for my pool is 6ppm. Cya is around 45. I think I'm going to start keeping it at 8ppm.

Thanks, I have the Taylor 2006c test kit. I lost 1.5ppm overnight. I didn't start the slam process properly, no time to vacuum but there's really not much in the pool, Few small debris. I just added more liquid chlorine back up to shock level. And will run the pump. Pool store test had...

Starting last year I had small specs that look like dirt that get caught on creases in the floor of my vinyl liner of my 18' round above ground pool. Last year I thought it was just dirt or something. It wasn't until later in the season when I got green algae bloom that I found out my stabilizer...
