Thanks. Is there a suggested method for confirming the proper seating of the catridges?

So last season, I needed to add a touch of CYA, and I did so by very, very slowly adding it to one of the skimmers. Imagine my surprise when a minute or so later I started seeing little white granules coming out from the return. I thought that certainly was indicating a rip in one or more of...

So I educated myself a bit on this test. This thread was helpful: Turbidity measurement (was ) [Archive] - Trouble Free Pool Last year some folks from Johns Hopkins and Cornell published an open-source, low cost (~$30) turbidity meter that correlates 99.5% to commercial meter readings in our...

I assume this test works because the reagent causes the sample to become opaque in proportion to the level of CYA present. Roughly correct? Is anyone aware of an attempt to characterize the opacity using an LED and photo diode? It seems to me this would be relatively easy to implement. I have a...

I just received my CYA standard and a brand-new bottle of CYA reagent, and I too believe the dot is extremely visible at the 50ppm mark. I am certain I used it correctly, filling the test bottle to the bottom of the label with standard, filling to the top of the label with reagent, shaking...

My 16 month old EcoStar is making a terrible noise (sounds like a bearing went). I removed it from the pad in anticipation of taking it to a service center tomorrow, and I noticed that the motor cover is corroded. Anyone ever had this problem before? What's the cause? FWIW, the warranty is...

Thanks, guys. I'll try the adhesive patch.

I purchased a new Loop Loc Mesh cover for our 18x36 IG Vinyl pool in November of last year. I installed it myself. This spring, I noticed two tears in the cover. I sent the a photo to Loop Loc, to which they replied: "The damange on your cover appears to be a punture. Please send the...

Re: Poor Man's Cleardeck -- Diameter of solar cover when ree For a 70lb cover, distributed over 20' in length, on a 4" OD / 3.75" ID aluminum tube, I calculate 0.3" of deflection at the middle. Is the sag from the ends splaying inward? Or? From what I read on line 70lbs is a conservative...

Re: Poor Man's Cleardeck -- Diameter of solar cover when ree If you look at the way cleardeck actuates, they insert a crank rod at a right angle to the reel, which probably has a bevel gear system to get the reel moving. I could rig something like that up, or I could hook up a small motor...

New IG 18x36 breaking ground in a month.... I love the ClearDeck. Hate the price. So I came up with an alternative. If I have my PB put a concrete trough along the deep end, between the wall and the diving board, about 16" wide and deep, I'll have an area where a low profile reel could fit. (I...

The FSEC ratings for most panels are around 1000 BTU/ft^2 (960 for Heliocol, 1060 for Fafco Revolution -- keep in mind the center states that ratings within 25 BTU/ft^2 are effectively equivalent). Certainly not having the webbing decreases irradiated area. It's hard to say how venting would...

I'm leaning strongly toward Heliocol. Here's why: * Heliocol panels are 'vented' meaning the tubes are separate, individual entities. That way, if wind blows across the panel, the pressure is equalized between the front and back surfaces and no lift can be gained. This means the panels are...

We have an 18x36 Vinyl IG being built in the spring. Thanks to this forum I've gone from complete neophyte (I never even knew someone who had a pool) to being almost literate. You've all helped me make some more intelligent decisions regarding my pump, filter, and chlorination equipment. Because...

You're right on both counts. I was looking at this post (http://goo.gl/3nsfQ) but I now realize that they were discussing the ICC (I think). It seems like having the timer inside would be a convenience. Is there any downside to that approach? Thanks for the help.

We're having an in-ground 18x36 installed this spring. The pool builder quoted a 1hp pump and a 250k BTU NG heater. I understand that the NEC requires that the pump and heater be on timers, and it seems that nearly everyone uses an outdoor mechanical switch, such as this: http://goo.gl/zjuxM...
