Hello, please help me get rid of green algae!

You should not be getting that color -- the test should end in clear.

Test your tap water. See what happens.

You have never achieved the endpoint which is to clear the pink color. You need to keep going. You can never add more chems if you have not reached a correct endpoint in any type of test. Dont be afraid to keep going, you need exact numbers. You can also purchase extra reagents so you can rule out contamination.

No, I don't think dilluting will help, it shouldn't turn orange. What is the expiration date on the reagents?

 

[novata]

expiration date 3/21. I just bought it last week. I'm afraid I'll run out of R-0871 ... but I'm rechecking again

 

[Flying Tivo]

Buy new set of DPD powder and R-0871 it will be cheaper than the extra chlorine you are adding. Are you using the SpeedStir? If not it would be a good time to do so.

I've checked with tap water, and its FC is 0.2. I've checked again with 5mL, 1 drop of powder, and by the 13 drop it turned from pink to somewhat clear but with some orange. I kept adding drops but I kept getting faint orange...at 40 drops I ran out of reagent. So I'm heading to the pool store.

I've attached the pics of my sample. The first one without reagents, second with powder, third at around 14 drops

 

[mknauss]

OK -- so that is not orange. It is not perfectly clear, but at those levels of FC it never gets perfectly clear. It is when the pink goes away.

I doubt a pool store will have R0871,

 

[Flying Tivo]

You have a FC of 13, get FC to slam levels and keep goingFC/CYA Levels

 

[novata]

You are right. They don't have R-0871. I'll have to wait for my Amazon package. And...meanwhile ...I'll have my eyes checked! lol

PS: Is R-0871-C the same as R-0871?

 

[mknauss]

You want the C - it is 2 oz bottle.

Or, TFTestkits.net has fresh reagent refills.
