I just purchased a 20 gallon tank from the goodwill and this filter came with it. Is it too small for 20 gallon or should I buy a bigger one?

Think so....I have a 10 gallon tank with 3 medium fish and it works fine but for a 20 gallon tank you should get the right sized filter to keep the fish healthy.

I sat mine inside of a ten gallon tank when I was moving, it fits but takes up almost half of the tank. It will be fine if you have something less than 4-5 inches in there. Just keep in mind the water level has to be a certain level for the filter to function properly.

You might be able to use it. That size turtle is a little big for that size tank. I use two of these filters both in the corners and it works fine. You could try one and see how it goes. If needed, get the second one. Personally, I don't change the filters as often as they recommend and I've been using this system for probably at least 6 years.

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

It should be ok..that filter is up to 40g.... That thing should keep your tank pretty clean. Plus you can adjust the flow so your not creating a whirlpool inside the small tank. IMO I'd upgrade to at least a 20 or 30 gallon... Hope I helped!!

I use this on a 20 gallon tank. It does not seem to have a very strong flow for its size I would not recommend using this in a small tank such as yours. The unit itself would be too large for your tank and too strong. If you have a good filter pump for your tank I would think that it would be sufficient for circulation.

You need to replace the sponges IMMEDIATELY with a better filter medium. Look through the reviews and you will find what to use. Otherwise this is a great, quiet little filter for very small aquariums.

Casey is correct....this is way to small. It will be okay temporarily, but you will have to get a bigger tank and a better filtration system. It's cheaper/better to just start out with a bigger tank. Even the 15g-20g suggestion will be too small at some point. Here's a link to a really good care sheet: http://www.austinsturtlepage.com/Care/housing.htmAt one point I had 7 turtles and they are great animals, but they do require a lot of work that pet stores don't tell you.

Hi, the filter that comes with this tank is JUNK. I threw it out. I have 2 GloFish tanks and they are awesome! I bought a whisper 20 gallon filter that takes large cartridges; my tank is SUPER clear and requires less maintenance with my bigger, better filter. Anyways, good luck.

I am using a regular filter size and it is fitting perfectly. I had a lot of them in my cabinet and I did not have any problem, so I did not need to buy any.

Yep, too much. Depending on the tank's dimensions, and assuming it will even fit inside your tank, it would "work" if you can adjust the bubbles to an appropriate minimum. But it is definitely larger than you need for a one gallon. A smaller version of this type of filter would be better, like the "Jardin Fish Aquarium Mini Cylinder Soft Sponge Water Filter, Black". Still, I would want to be able to dial down the bubbles for a smaller tank.

I am not an expert but I believe the numbers refer to the dimensions of the filter. You purchased a 20 inch wide by 25 inch long by 1 inch deep filter and want to know if a 20 inch wide by 20 inch long by 4 inch long would fit. I do not believe so. It is five inches too short and 3 inches too deep.

well you can also find bigger sponge filters these are great filters but only for like a 10 gallon tank personally I like the Magnum 350 canisters

On the front of the box it says it is good up to 30 gallons. I have a 20 gallon tank myself but I use the next one larger and it does a great job.

I would SO use this for a 10 Gallon, the extra filtration is never a bad thing, and allows for the future upgrade of aquarium size. Often people overstock a 10 gallon and this size would keep up with the extra waste.. It doesn't make it OK to overstock though. I Purchased an aquarium kit (25G High) and this was included, I will put this on my 10 and transfer my Fluval C3 to the 25. My filter measures about 7''. Soooo, long story short I would recommend you trim your hood. Just cut it up, don't sweat it..

Make sure to check the dimensions of your existing aquarium to ensure this will fit in it, but otherwise it "should work. I'm always a fan of having a little extra filtration capacity, since if the filter is rated for 15 gallons (as this one is) that's assuming its clean and operating normally. Getting the PF25 would give you a little extra filtration and flow in your tank. Those are just my thoughts. I really liked the idea and concept of this filter and it seemed to work fine for me, I just couldn't get it to fit under my aquarium shroud, so I ended up returning and got a secondary fiter to support the primary one. UV is definitely a good thing for your aquarium though! Make sure to check the dimensions of your existing aquarium to ensure this will fit in it, but otherwise it "should work.
