First test readings of season

[michael3]

BigDave, pressure on filter is the same as on recirculate is runs 17, runs about 10 on backwash. I closed the valve between my skimmer and pump alittle bit, the pressure on the gauge dropped to about 10 psi, but the flow coming back into the pool felt just as strong, and it sounded like it was putting alot of pressure on the plumbing lol. I posted under the pump forum about my sand, I put new quikrete pool filter sand in from home depot, the size of the sand is .85-.425, the sand filter says use .45-.55mm is this about the same? wondering now again if I damaged a lateral when I put new sand in. I cant tell if I`m blowing sand in the pool, I can still only see about 8 inches down.

I just went out to pool and decided to look at the old sand that came out of my filter, and the new sand that had blown out the backwash pipe when I first put it in, the new sand was alot finer was no where the size of the old sand that came out. Think I will empty the sand filter and double check the laterals and again replace the sand, this time with pool store sand and not pool filter sand from home depot. I know the pump is to big for my filter but this has to help I think lol

I havent had a chance to change the sand yet, I tested my water at 10:30 last night and had a FC of 32.5 and CC of less than .5( it didnt even need a full drop to clear it), this morning at 8:00 I tested and FC dropped 1 to 31.5 and CC was still less than .5 Water is still a lime green color and very cloudy, cant see over 8 inches down. When I added all those bags of shock Xtra blue, I think it was 12 of them over a span of a week, copper was .26% of the ingredient. Is there a chance I`m dealing with a copper issue and not an algae issue? FC has been at or slightly above 30 for going on 5 days now

[Watermom]

Yes, I think it is likely. I'm going to ask Ben to have a look at this thread and get his take on it.

Thanks watermom, it's so frustrating, to think I am the cause of this mess lol. I was reading on a very similar site that uses BBB method that when copper is the reason for the green water, it's usually clear green and a seqesturant? Lol will help with the color. Well ours is green and cloudy, I'm almost thinking its a copper(green water) and cloudy is the dead algae that won't filter out with my mismatched overpowered pump/filter and maybe wrong sand. Sorry for long post

+ Post your pH, alkalinity and CYA test results, and tell me how you tested.

+ Do NOT use any more products with copper

+ List -- exact names of product and manufacturers -- all specialty pool chemicals used this season: algaecides, clarifiers, sequestrants, phosphate products, etc.

ok Ben, ph is 7.0, alka;inity test was 100, the color went from blue to yellow, the directions on my P233 said with high FC that is normal? CYA at 70-80, using the tester from my P233, ph test was from oto drop. All new reagents. Everything that has been added since the start of season: I have added over a 1 week period 12 1 lb packs of Aqua chem shock Xtra Blue, ingredients of 63% dichlor, .26% copper,36% other. thats per 1 lb pack. 2-3" pucks Aqua chem 99% trichlor 1% other. been using walmart bleach, and this stuff from home depot from sunbelt chemicals, its called Smart Liqui-Shock, ingredients 10% sodium hypochlorite, 90% other, contains 11% available chlorine. I have been using this as my main source for the past 2 weeks to keep FC up. I havent added any "shock" product or pucks in over a week, so when I tested CYA last sunday and got 55-60 maybe it all wasnt disolved? so the 70-80 I think may be closer to being right
