    Cartridge filter in series with DE filter, and balance water before or after slam method?

    I did try the clarifier. I dropped 2 ounces in and let it go for 24 hours with the cartridge filter. I was very particular about making sure I didn’t overdoes the pool, as Ive read adding more Will actually increase the cloudiness, I only saw a slight change. I then decided to go back to the DE...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Putting my final update in. Pool is clear. In fact, I think this maybe the clearest I’ve ever had it. I wana say thank you again to everyone for the help. I did not drop in FC overnight, however it was not an official OCLT. Tonight I will dose to slam level, confirm FC ppm after dose, and check...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Thank you. So I found I already have an unopened bottle of what I believe is a polymer type clarifier. Can I use that? Or best to go with the chitosan clarifier? Also, as for OCLT, I would assume any rain overnight would invalidate the test correct? Thank you again.

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Thank you very much. How many OCLTs you think is necessary, at least 2 or 3 nights before I can safely determine that everything is dead, and can add clarifier? And once I’ve passed multiple OCLTs, should I maintain slam levels while the filter is cleaning up the cloudy water? Or can I let it...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Yes, when I do truly perform an oclt I will dose the pool to slam level accordingly, test after 30 minutes of circulation to confirm chlorine level and check again in morning. In addition to my questions in the previous post, I now see flocculent is really meant for using while vacuuming to...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Updating again. I’ve finally made some progress. The water is now a white blue color. Almost all the green is gone. I ended up changing out a 3rd of the water to lower CYA levels, but prior to that I was starting to see the green drop out. The water change just further helped it. My current CYA...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Yes the first test I used the 25ml measurement, then all others have been using the 10ml, .5 ppm scale. I did see in another post, someone had said they were using 5ml with 1ppm per drop scale. Thanks

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    This is what I was thinking. Unfortunately I got called into work today, so I won’t be able to get started till around 3 this afternoon, but I’ll drop my pump in and then pull a siphon on 2 different hoses to drain it down some what quickly. Then the fill process. Once I start filling should I...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Thank you so much again Newdude. This really is very helpful. My thinking was that you needed to be above the 40% of CYA for the chlorine to oxidize everything and that anything under 40%, the CYA would inhibit it’s ability to work. So I’ve been going with 50 for my CYA, so I’ve been...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Just a couple more questions, My combined chlorine is consistently at 1 at every test. Shouldn’t it be going up suggesting that the FC is doing its job? Again, no real change in color this morning, so I’m just concerned if there could be any other issues. I’m going to retest my cya today and...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Here’s the current color. Not pretty at all. I do think I’m starting make headway though. The water is more of clear green, rather then the hazy green it was. I can just barely make out the pattern on the bottom. Also more importantly, this morning FC was at 3 and I added 2 gallons of chlorine...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Again, thank you very much for all help and encouragement. I’ve had this happen a few times in the past couple years, and I’ve always been able to bring it back within a couple days with a couple bags of shock. But this has been the worst I’ve ever had it, and I know I’ve only actually just...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Thank you again. In my previous experience, eventually the green dropped out and the pool turned cloudy white. Will that likely happen? This is the greenest it’s ever been, and no progress really has been made? I ask because I made the switch back over to my cartridge filter, and I’m getting no...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Thank you again for all the help. I decided to go ahead and added 1.7 gallons of chlorine to the pool as per pool math to get it up to 20ppm. I added it at 9:30 last night. This morning at 5am, I tested again. Found FC 3 and CC 1. I added another 2 gallons of chlorine. The color of the pool...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Ok. Updating again. Test kit showed today. Tested at about 2pm today: Used the FAS-DPD test, FC: .2-.4 (think it was actually zero, it never turned pink, had to add additional powder to make it pink, and 1-2 drops to bring it back to clear) CC: 2 pH: 6.8 TA: 60 CH: 150 CYA: 0, never even turned...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Thank you guys for the responses and help. Looks like my test kit is due to arrive tomorrow, so pretty ready to get this under way and fixed. I’m suspecting that everything will be low, alkalinity, ph, and cya. If it is, do I adjust alkalinity before ph? Do I just adjust ph and cya? And then...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Just updating this thread a bit more, and looking for a little more advice. Test kit hasn’t showed up yet, ugh. In the mean time, I’ve been adding about a half gallon of 10% sodium hypochlorite liquid chlorine every night once the sun is just about down. And let the filter run most of the...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Thank you all for the tips and help so far. Test kit is scheduled to be here today. Last night for the 3rd time, I disassembled, and cleaned all old DE from the filter and reloaded with 4lbs DE. Currently doing a bit better about not clogging up so fast. I added a gallon of 7.5% sodium...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Thank you. So I guess really I’m just hung up on the filter flow. I was under the impression the filter flowing was pretty important, for of course filtering, but also for helping to mix the chlorine. I know the point of slamming the pool is to kill the algae, and sanatizer the water, just...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Yes, that seems to be the consensus here on the thread, that an additional filter will be unnecessary or maybe even more problems rather then help. As I’ve stated a few times though, while I had hopes 2 filters might clean better, the idea was that maybe I’d have a better chance of keeping the...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    I agree with that. Absolutely. But keeping the filter flowing is what’s really slowing me down. Unfortunately, no. There’s is no multi port valve so I cant just recirculate. I had thought about temporarily rerouting from pump right back to pool for a day or 2 while slamming the pool and then...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Yes, I do already have the cartridge. I already have everything to make the setup. I do agree that there’s the chance that this setup may not go as well I have hope for, and would not spend the money to try and do it. My thoughts were, last year while trying to clean up dirty water, the...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Thanks, I currently have a k2006 kit coming for ph, alkalinity, ph, cya, and dpd-fas test. I was planning to perform the slam method. But you would chlorinate before adjusting cya? I thought without any cya, the chlorine will burn off quickly before thoroughly sanatizing the pool. I agree that...

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Thank you for the tip. Might be a bit before I could justify an additional cartridge unit though. I do have everything already to setup the cartridge in series with the DE. You don’t think the cartridge would help pull some contaminants before going thru the DE filter? Thanks

    Cartridge filter in series with DE filter, and balance water before or after slam method?

    Hello all, made a post last year looking for help, managed to get my pool squared away last year, but I think it was luck. Same problems I had are reoccurring again this year so here I am. This may be a long post so I’m gonna put the main 2 questions here close to the top. And I’ll provide the...

    Cannot get water to clear

    Thank you all for the responses again. I’m currently using test strips, they test for FC, pH, alkalinity, and CYA. I’m sure there’s a good possibility that they are not that accurate. Can anyone make a recommendation for a test kit? I’m looking at adding a Taylor K1515 for a FAS-DPD kit and...

    Cannot get water to clear

    Thank you for the responses. I’ll use the slam method. I know the slam method calls for liquid chlorine or bleach. Can I use di-chlor since I’m trying to raise the cya as well?
