Thanks - I just tested this morning. I have a Taylor K2007 kit. Here are the numbers:
Oh darn. The K-2007 test doesn't include the test we feel is necessary to monitor FC and CC accurately up to 50ppm- the drop based FAS-DPD test. You only have the DPD test which is not as accurate because you're sort of matching colors and is subjective. You can get the element you are missing at TFTestkits.net TFTestkits.net
FC - 2
Too low for a CYA of aprox 40ppm
TC - 2
CC - 0 in that case?
People can actually have algae outbreaks without CCs. I know that's counter intuitive but it happens...
PH - 7.6
TA - 120
CH - 300
CYA - didn't do today but I was almost 0 last week and added 5 lbs CYA three or so days ago and ran filter for 2 days.
My math says that should have brought you up aprox 40ppm, assuming you really didn't have any other CYA in there. The tests only measure the CYA if it is over 20-30 (depending on test). THat would mean your FC is wayyyyyy too low, instead of just way low. Please see this chart- [FC/CYA][/FC/CYA]
Again, the water itself is crystal clear. I have been extremely busy with work including over the weekend this past week and haven't brushed or vacuumed in maybe 10 days my bad! I can tell you that the "outbreak" absolutely reoccurred where I had previously brushed thoroughly and that after that last cleaning I used Leslie's (plain old Algae Control) algaecide at the new treatment for 20K gal rate. Didn't work so well I guess...
Algaecide doesn't kill algae, it can help prevent it but we rarely suggest its use as long as people maintain proper chlorination levels. Some contain copper which only add problems to pools.
I should also add that I didn't replace the Duoclear cartridge this year which they want you to do as the old one had plenty of weight to it. It's a very slowly dissolving mineral cartridge that eventually becomes an empty shell. Shame on me if that's the cause of this nonsense but it seems kind of scammy that regardless of how much agent is left they want you to replace it every season. I would never get another one of these systems - straight salt system for me when this one goes.
No, copper doesn't cause algae. It causes stains and green hair.
Lastly, is the "type" of algae readily evident from the photos?
Slimey green kind....sorry!
Thanks!!!
Thanks
