    Yellowout

    I was recommended to put a yellowout like product (sodium beroxide) in my pool to get rid of mustard algae by my pool store. They told me not to put chlorine along with it because I already had a high amount in my pool.Should I add more or is it fine? Also will the algae be permanently gone or is that just a temporary fix? Thanks.

    Re: Yellowout

    Im pretty novice to taking care of a pool and I don't feel confident enough to Slam it and the water is already crystal clear except for the clumps of algae. I already have a high amount of chlorine in the pool.Too high to swim in. Will the steps recommended by the store be effective to treat the problem?

    Re: Yellowout

    Yellow Out is essentially EDTA. While EDTA does work as an algaecide, it does so by consuming free chlorine and creating monochloramine (measured as CCs on a test kit). Using that much yellow out will cause a massive chlorine demand that will take days to fix. I can all but guarantee your water will get worse, not better.

    You need to decide if you are going to follow pool store advice which will ultimately just drain your wallet OR if you are willing to take control of your own pool and follow TFP advice. The two are not compatible.

    Welcome to TFP! What part of Michigan are you from? Just curious if near Toledo.

    Our pool care system and those taught by pool stores do not mix. As such we do not offer advice on whether pool store advice will or will not work. It might, it might not. It might be temporary, might be permanent, we don't know. SLAM works, we see it work a dozen times a week. If you choose to follow the steps given to you by the pool store then it is up to you to decide whether or not it will be effective.

    I will say that it is unlikely that your chlorine is too high to swim if algae is living in it. It is also possible that you are not dealing with mustard algae. Without test results (taken by yourself with a proper test kit, not pool store testing or test strips) it is impossible to say on either count.

    I need to get a proper test kit. Do you recommend one off Amazon or how I should look for one? Prices seem to really range on them. I'm not too far off from toledo.

    Very few pool stores stock the kits with the test we consider essential, the FAS/DPD chlorine test.

    I recommend you order a TF100 and at least include the XL option. That will give you what you need while you are clearing the pool, and probably enough reagents for a couple of years normal use.

    The only other real option for a test kit is a Taylor K-2006. Be careful comparing prices because the K-2006 comes in sizes, designated by a letter. The basic K-2006 has .75oz bottles. You need to get the K-2006-C to get the larger bottles that you want. Even then it is a little short on the reagent & powder for the FAS/DPD test.

    Now, if you really want ot get fancy I also have and recommend the SpeedStir and Sample Sizer. They speed testing and accuracy.

    Both the TF-100 and the K-2006-C are available on Amazon, but you save some money on the TF-100 ordering direct in the link I gave you.

    Yes, I use the TF-100 from TFTestkits.net. It is the best value, giving you the most tests for the money. Pool School - Test Kits Compared
