    Cannot raise a low free chlorine level

    Hello, This is the third day since I started SLAM process, and just today, FC level dropped 8 ppm just in 7 hours. What I'm wondering is, FC drop has been pretty consistent for the last three days, and my pool is pretty clear (I would say very). Would it be possible that algae was not the...

    Cannot raise a low free chlorine level

    Will try. I see. What would be the optimal rpm after brush? Would it be better to pump fast at least for a while after brush before algae gets settled back on the surface of the pool?

    Cannot raise a low free chlorine level

    Yes, I reviewed it before I started it. Since I have to go to work, 3-4 times a day is not practical for me. For curiosity, how does clear of dead algae occur? Are they filtered? If so, why not "live" algae? Why is that we have to kill them first?

    Cannot raise a low free chlorine level

    Hello, Today is the second day since I've started a SLAM process. 5-4 night: shocked to 20 ppm, pH 7.2 5-5 FC 19, CC 0, pH 7.2 => FC raised to 20 5-6 FC 14, CC 0, pH 7.2 => No actions taken yet Does this look like a common/traditional conditions that require SLAM? Pool gets cloudy while...

    Yes, thank you. I've also found it. I will add 2 gallons right now.

    Cannot raise a low free chlorine level

    I've just added muriatic acid to lower pH to 7.2. Then, I have KEMTEK Chlorinating liquid. Where can I find tables or equation to calculate to find its volume to raise FC to 20 ppm?

    Cannot raise a low free chlorine level

    You mean forget about 5ppm (your first reply today), and perform what you suggested in your second reply, or do things on both of your first and second reply?

    Cannot raise a low free chlorine level

    Hello, I finally re-did the test using the new kit (K-2006) that I purchased, and the results are as follows: Free & Combined Chlorine Color didn't turn pink even after adding 10 scoops of DPD Powder, so I stopped assuming both are 0. pH: 7.8 TA: 200 ppm CH: 500 ppm CYA: 48 ppm I plan to...

    Cannot raise a low free chlorine level

    Got it. When I tightened the lid and plugs, it already seemed like reducing a leak quite a bit! I am still monitoring on it right now. Alright, thanks! I'm ordering the kit now.

    Cannot raise a low free chlorine level

    I was looking for one that also includes salt measure. I tended not tightening the pump basket lid because sometimes it was hard to open. I've just tightened the lid and two plugs as well, and hopefully this solved a leaking problem.

    Cannot raise a low free chlorine level

    I was also recommended not to use the expired kit. That is why I used the strip instead. Expired kit vs, test strip? Where do you mean by the suction side? Does this mean that you have to dig the dirt out and check all the pipes under the ground? Do you know approximately how much this would...

    Cannot raise a low free chlorine level

    Last night, I shocked the pool yesterday using 1 gallon of liquid chlorine, and it's level is still "high" currently when measured using a test strip. This may indicate that the reason for a low FC was not its consumption by algae at least. I'm not still sure what the major problem for having a...

    Cannot raise a low free chlorine level

    Another question regarding removing algae is, will dead algae after treated with liquid chlorinator be filtered by going through the filter or will they pass the filter and return to the pool (I have a DE filter)? If the latter is the case, I'm wondering what's the reason for brushing? This is...

    Cannot raise a low free chlorine level

    Got it! Thanks! I don't have a water softner at home. Would this be a major cause for those scales generated on a SWCG? I glad I joined TFP! I already learned million things!

    Hello, I've checked each vial in the kit, and about 2/3 were expired as early as July 2019.

    Cannot raise a low free chlorine level

    I see. I will certainly try that. Another question regarding the cell is, I opened an cleaned the cells using <10% muriatic acid, then when I did that. I just opened its cap and I heard water in the filter is going down or released. Would this have caused the air in the system?

    Cannot raise a low free chlorine level

    I don't think I'm getting air out of returns based on that the pump is pretty filled water all the times whether turned on or off. Yes, the filter has an air release, and it is fully closed. Got it! Thanks!

    Cannot raise a low free chlorine level

    So, as I posted above, a potential scenario is that there is no issue of generating FC but it consumed so fast so that a recommended level is not maintained? I see... Would you recommend any particular liquid chlorine or any should be good enough? I don't think it has reached up to a terrible...

    Cannot raise a low free chlorine level

    Thanks for your advice? Would you recommend specific type of liquid chlorine (ex. Cal-Hypo) or any should be good enough? I see what appears to be green algae but I don't think it has reached to a terrible point yet. So, a potential scenario is that there is no issues of generating FC but it...
