Re: LOOKING FOR REASONALBLY PRICE EFFECTIVE GENERAL ALGECIDE Waterbear, I think I have determined a part of the problem. 18,560 underground plaster pool. Hayward DE filter FC 3.5 TC 3.5 PH 7.6 T/A 100 CH (waiting to order refills so I could not do this test) CYA 70 I have been trying to...

Have a spot here and there of a yellow/brownish what I believe is an algae. It brushes off and a chemical that was rather expensive seems to have an effect but I'm wondering if there is such a thing as a reasonably priced general use algaecide chemical I can use in an underground plaster pool...

WHAT IS THE TRICK ?Re: TF kit CYA what am I doing wrong? So what is the trick to this test? Do you pour slowly till it first disappears, register that point or do you wait till the water settles and see if the dot shows. Watch out for that reflection of your head against the sky - can look...

Thanks Jason re: Hayward Jason, Thanks for the info re: Hayward no rinse. Best, Thomas

Refill water and aerate for pH As always thanks for your responses. Question about aerating: Is the spa/pool boost setting on my Hayward valve a way to aerate? I also have the jets inside the spa. I will do a drain and fill first then see where everything is and go from there. - will...

Thomas 4:35pm chemical read I've just come in after testing again - third time today. It is now 4:30PM I tested this morning, mid day and now a half hour before the pump shuts down for an 8 hour day. FC 6.5 CC 0 TC 6.5 pH 7.3 T/A 110 CH 340 CYA 100 CYA seems twice the highest...

CYA Test making me crazy Started today on a clorox ultra 6% regiment in place of the pucks. Went out this morning and at 9:30am here is what I got: FC 1.5 CC 0 TC 1.5 pH 7.3 T/A 100 CH 340 CYA 60 added 1gal + of bleach. AT 1:15 I tested again: FC 5.0 CC 0 TC 5.0 pH 7.3 T/A 110 CH...

Thank you Dave Jason Thanks. I will follow what Dave suggests with the bleach daily and am going to take a sample of my water to a local pool store. I will report back. Best, Thomas

How am I clorinating? Dave, Clorox Regular 6% name brand. Using the charge as a guide. Jason, I was hoping 3.5 was good - right in the middle. Do you think I should do anything with any of the numbers I've listed? Thanks. Thomas

CHLORINE So when I think chlorine I am thinking FC/TC numbers. IF this is correct then with a CYA of 40 the Chemgeek's chart is telling me the FC range is min2.9 to max 4.6. Am I better off at 3.5 or lower being I understand higher chlorine aids staining in pool. Here are the latest...

UPDATE: Okay, so I found out the pool is 18,000 gal and the spa 560 gal from literature the previous owner left here - he had the pool built. This meant the amt of DE I put in there the week before was way too much, so this is what I did. I did a good backwash and then added 60% of what the...

If I get an FC reading of 3.5 and CC of 0 for a TC of 3.5 and then when I use my small kit, should it read somewhere in the 3.5 area of the scale? I just tested it and the number is closer to 2 than 3.5. Any thoughts? Thank you. Thomas

DE CONTROLLER QUESTION Waste, I don't know if I got a question through to you earlier concerning the controller on a Hayward D.E.7220. You mentioned you were familiar with the Hayward. My controller is only four positions: Filter, Backwash, Waste and Pool/Spa Boost. Any suggestions about...

Calcium Thank you I'm on to the stickies. Thank you all for your help. I will keep the progress of this updated so others who might have the same problem can benefit. Best, Thomas
