Can you use these in a fresh water fish tank?

if you have a wet dry bio filter system yes they bred the bacteria on them grow to remove waste...

Yep. They just create a large surface area for the bennificial bacteria to live on. They are pretty large though. Make sure you measure your filter and get the right size for your specific application.

Yes! They are great in both fresh and salt tanks. I use mine in a fresh water tank and some in a fresh water pond too! Make sure you order a lot tho. Over 100 for a small wet dry filter. I ordered 50 and it was not close to enough! Needed about 200!

They probably can as the ball portion of these are only a little larger than a quarter so if you can get that size into your water tank they should work.

hi they need salt water ,so if there is fresh water in ther no you cant put them in.

Probably unless you set it at the maximum height. However consider adding floating plants. They are one of the secrets to maintaining water quality, especially in a small tank. They will filter the light to the rest of the tank and filter many of the excess nutrients and waste products. I have them in all my tanks and weed them out regularly. Please dispose of them properly to not contaminate local waterways.

I use them in a turtle tank but without the model name/number of your filter, I'm not sure.

Yes on the crabs. Haven't used them in fresh water yet but they should work. Worked great for us and easy to store.Good luck and the price is right.

I would not do that. Not sure how this stuff affects ph etc... Use aquarium specific materials.

I don't see why not if you are buying the smaller pellets and the fish are already big mouthed. For instance, these don't work well with guppies whose mouths are too small. The fish need to be able to grab the pellets. The pellets don't muddy the water so a tank should be fine. Is there room in your tank for the fish to jump at the pellets without hitting the top of the tank? The pellets will float on the water. They are designed for fish that have colors like Koi and large goldfish. Have you considered purchasing the flakes?

I would not recommend using them for that. They are not as thick as the ones used for fish oil and you would need something that held together better. I believe the weight of the fish oil may cause them to come apart.

I cannot see why not, although they are very easy to clean and I just rinse them quickly with a sponge and leave them to air dry in a strainer.

Yes, but beware that some ammonia pads are freshwater only. Something to keep in mind if your have a saltwater tank.

I'm no expert, but these stones are smooth and kind of large, about 1/2 inch in diameter, so they should be safe for any species of fish.

I used them in my pond and it didn't affect the goldfish.. I am going to use them when I clean my 75 gallon Discus tank, If any problem occurs I will put it on Amazon.

Yes! I use them in all my 5 gallon betta tanks. It is the only filter I have found that does not produce to much current.

I don't know. I Dont Recomended for fresh water. It don't bring the fish color like the florescent ones.

You can actually place this filter completely under water. Without knowing what type of tank (bowl vs. rectangle) I would suggest putting this almost on the bottom of your tank and direct the flow somewhat against the glass to cause a current. If placed correctly the waste should make its way toward the filter.If none of that answered your question, I apologize, I have not kept goldfish since I was in elementary school.

I haven't used it in a fish tank, but I would say No. It's very fine and dusty and you would be better off with the fine gravel rather than sand for use with fish.
