Bubble solar cover?

So, putting in a liner has set back my plans for an auto cover.
I want to get a simple cover to a) help with heating b) debris

Would you suggest a clear or blue bubble cover?

Just my $.02, but the cover probably won't help with debris. Cover might hold it up, but inevitably as you are taking the cover off of the pool all that debris finds the water. At least for me.

Cover is still worth the expense tho.

Allegedly clear will heat the water from the sun a little better than blue, but also let the uv through to consume chlorine more.

8 mil is a good size. thicker covers are much more difficult to handle.

I advise buying them on ebay. The same pool companies selling them on their website typically
list them for 20-30 bucks less on ebay to move inventory and most often include
free shipping.

Neither blue nor clear will let in much UV at all. The polymer material used to make the covers is basically a UV stabilized polyethylene. The UV stabilizers absorbs the UV strongly in order to protect the PE from degradation. So either cover will work and block most of the UV.

The covers themselves don't capture much heat. Their primary benefit comes from the fact that they stop evaporation of the water from the pool which is a huge source of heat loss because the latent heat of vaporization is very large for water and so when water evaporates it takes a huge amount of heat energy away with it.

I found that when I used my bubble cover last year, my pH rise all but stopped (no CO2 outgassing) and I was able to turn my SWG all the way down to 15% and still maintain adequate FC. I also built one of those DIY Solar Rollers. The problems I ran into are these -

1. My pool is free form with a lot of curves and it is roughly 18' X 38'. So even with the cover split in two, it was a major PITA to take on and off the pool. Each roller was over 18' long and even with an 8mil cover, they weighed a ton due to water retention. They were very unwieldy and required 2 people to take off and put on.

2. I live in the desert with day time temps well over 100F from mid-May through July. You simply can not leave a pool covered during the day or else the water temperature will hit 100F in no time. Hot water will have a much larger FC demand and will just be uncomfortable to swim in. Because of point #1 above, the cover basically was left off all summer long which negated any chemistry benefit.

Because you live in Massachusetts, I believe a cover will help you a lot and your pool is basically rectangular which means you'll have a much easier time cutting the cover up into more manageable sections. Just be advised that they do weigh a lot when they are saturated with water so you might need an extra set of hands to help out.

Thanks all. I am planning to do a diy roller as a project with my kids. And as far as the debris going into the pool, I do know that the stuff on the top of the cover will end up in the pool, but hoping it will be in a more contained area instead of over the whole surface of the water. 😀

Debris going from cover to pool isn't as big a deal as it seems like it will be. Well worth the effort for a warmer pool.

I would go to Ocean state Joblot for a solar cover. That;s where i get most of my pool stuff. I also pull my cover back durring the day and cover it at night, which is what was recommended to me on this site to get things to heat up as quickly as possible. The cover helps hold the heat in the pool, but won't help it heat up any faster.

Yep, thinner is better. Easier to handle, stops evaporative heat loss just as well and last almost as long, if not just as long.

Ordered from Amazon. I opted for a larger size of 20x40, our pool is 17' 10" x 36'10" plus the bumpout for the stairs.
I am seriously thinking of rigging up a system where we can wind it up to the roof of the pool house (very close to deep end of pool) biggest concern is not wanting to get it ripped on the roof.

I got a brand new 12 mil sitting in my garage right now, still in box. I am hoping to sell it locally, and then order an 8 mil cover after reading more reviews about the weight! Thanks guys!

I just ordered from the link I provided above. At 20x45 I don't need any more cover to wrestle.

Protlost,
I ordered the same one, came from the same company (maybe mine is 40'?) Through Amazon it was something like $90.00 free shipping.
