How many would you recommend for a 25000 gallon in-ground pool?

I agree with Chris' comment. I am in metro Atlanta have 1 20' and on a nice sunny day I can raise the water temp 5 to 6 degrees in a 20,000 gal above ground pool. Hope that helps

it depends on where you live and amount of sunlight. Also whether or not you use a solar cover.

depends on the size of your pool mine is a 10,000 gallon and i use 5 pounds

200 Is A Great Amount For One of The Small Size Plastic Pools (One That Is About 3 - 4 Feet Across)Anything Bigger And You Will Most Likely Want More Balls. We Had 200 In A Small Plastic Pool, Kids 1 - 7 Coul Run And Jump In With Out Knocking Many Balls out

Inground. The 250,000 BTU I bought heats my 9 x 30 pool in Palm Springs quickly (about 2 to 3 degrees an hour with air temp of 75 degrees) and at about 30% less cost than 14 year old heater it replaced. I would guess you would need at least a 400,000 BTU for your pool to get the same performance. A 250 may work but it would have to run much longer than a larger heater. If you go Haywards web site I'd be surprised if they didn't have a calculator that would tell you exactly which of their products would work best on your size of pool.

Thank you. I thought I read you use 20% less of this then sand. Our pool is 23,000 gallons, so I thought we would need 5 bags.

We started with 200 and they barely covered the bottom. Ended up with 800! Well worth it though. That was 6 years ago and our boys still use it and every friend that comes over goes straight for it. Now that they are older we do have to replace the pool about 2x year, but I stick with this one. It holds up gear.

A single 150 would work. These never get very hot but just put it where your have the highest circulation. I have mine next to a U4 submersible filter in my 50 gallon tank. Quite frankly, I keep my place warm/cool all the time, 68-80, so mine probably does not come on a lot anyway. If you have African Cichlids that would be different but I just have SAE, Platys, Japanese trapdoors, etc. which like it in the mid 70's anyway.

I had a above ground pool and had two of them and they did great so I would say you need at least 4

I have the 400, recommended by my pool guys. Probably has to do with the size of your pool, and the amount of water/ surface to be heated. We have had ours for three seasons now, love it!

We only use them for big inground pools. The installation cost can be very high. We charge almost as much as the cost of the unit. Don't use it for obove ground pools it's too powerful and expensive.

2 is recommended. 1 for every 2 feet. I'm assuming your 75G is 48x18 footprint.

I'd be hesitant. 25w is way oversized for a one gallon. marineland makes a good 10w preset that I've used in 2.5's but even then the water was warmer than I expected.

Approx. 300 gallons. We fill close to full for our 3 year old grandson but he wears lifevesr. I add one small Dixie cup chlorine about every 3-4 days and keep basin or bucket of water next to pool to dip feet in before getting in (Helps keep grass out) and to keep from changing water too often. Hope this helps!

I have this pool and used well water, Never had a problem. Was just scared using 15000 gal. would be to much for my well

I reccomend you grab two of the biggest or two of the ones a size smaller than the biggest. I have 2 of the biggest in my 120 gallon reef and the current could be a tiny bit more

I used one for my in ground pool and was not satisfied. Clogged too often. Went for a 48 sq ft DE unit. Overkill but pool sparkles and very low filter maintenance
