what size tank is this good for

I am using it in a 50 gallon tank. I think the next size would be best if going any larger than this.

We are using it in a pond. Our pond is approx. 300 gallons and it works well. I do not think it is for fish tanks. It is for outdoor ponds

How much smaller? I use a 5 gallon tank. It was half full after 1 weekend of use, twice a day.

No this is for an itty bitty tank, maybe 1 gallon, and itty bitty filter. :)

I am using this in a 55g tank, so yes, bigger is better in this case. First one I got was defective after 6 weeks, so crossing my fingers the replacement will be trouble free

The pf15 worked great for my tank absolutely loved it. It depends on what size tank you have.

My tank is 30 and this one works perfect since its right in the middle of the ranges. If u have a 20 I'd go with the smaller one.

Yes it should fit, but if not you can make it fit with some minor modifications. Tank size should not make a difference.

Hi,I have a 10 gallon tank and it's fine! I didn't think there would be a smaller one. It definitely does the job. X

I would always go larger than what I need. I have a 55 gallon with big oscars and I bought the xpl rated for 175 gallons. A bigger filter allows more water fitter action per minute and turtles are pretty dirty. My son has 4 turtles in a 45 gallon with a filtration platform plus a xp filter 4.

It works really well for my little turtle. I'm not sure what kind he is but he is about the size of my hand. I got him in a 15-20 gallon fish tank with about 4-5 inches of water roughly and the filter works good.

I ordered this a month ago for my 23.5 gallon and it fits great. Very sturdy and easy to put together. Just check your dimensions, my tank is more wide and its the perfect fit.

Yes, it should be good for a 40 gallon tank. I have a 29 gallon with a Whisper 30-60, but I have other accessories.

Yes, I think it's perfect for that size. I have a 24" deep tank (90 Gal), and it's perfect.

It won't hurt but its not necessary. The large size is meant for a 110 gallon tank or larger! I use a small one in my 60 gallon tank and it works great.

I think this would be way too big and strong for a small tank. You're better off with a siphon type vacuum like the Aqueon mini siphon vacuum but you may want the medium size one. I use the mini one in my 5 gallon.

Depending on the size of the tank I I would say yes if its larger then a 50 gallon. If 50 50 gallon or smaller just put it in the middle.

It's fine, I use mine in a 55 Gal so you have plenty even if you decide to go to a bigger tank. Enjoy these are the best heaters.
