Can use these in Fresh water fish tank

We've been using them to filter our outdoor goldfish/coy pond for about 6 month. Works pretty good except when it gets hot out. Don't know if anything can keep up with the alge then.

Yes... That's what I use them for. There good for both salt and freshwater.

yes I use them for my koi waterfall filler.... I would introduce worms to the filter as well red wiggler work well

I wouldn't suggest it, they aren't waterproof just water resistant. I'm almost positive they would get wet and short out and possibly pose an electrical hazard to you and your fish. They do make submersible led lights for your aquarium tho. I have some and they're worth the few extra dollars. Your local pet store probably has them for about $20. Hope this helps

No problem at all. If you also add a little white vinegar to water will also freshen them at the same time.

I don't know. It's probably best to contact Tetra. I don't really know the difference in a reptile tank and a fish tank. My guess in that it isn't a good idea, since it wasn't designed for fish the tank may not be able to hold up to the pressure of the water. The glass may not be the same standard as fish tanks, the sealant may not be strong enough either.

These are to be used with spring water and they only eat yeast and egg yolks. Your fish will only eat them.

We have never used them for fish as they are not that large, however they should work fine for smaller pieces of fish or fish steaks. I got them for my wife to bake olives since a local restaurant uses similar dishes.

Yeah, I bought some of these at a fair one time and they had them in fish bowls. I do the same, with plants also, I just clean them regularly

Shouldn't, you can just take them out. Mine don't make noise other than the water going back into the tank. However if you're tank is saltwater I'd keep them in cause of the useful bacteria.

I'm not sure. The package says salt water. Maybe you should look for the Gulp that is good for fresh water. I don't know if the fish know the difference.

In general no. these are not high intensity bulbs and the ballast will not drive high output bulbs. Unless your tank is very shallow, or you plan to put a few of these on it, this is probably not your best choice for a planted aquarium.

Hypothetically yes you can put these in your tank and due to the high surface area beneficial bacteria would make a home there.. But if you're planning on doing this in lieu of having a biological filter inside your filter I advise against it, it simply wouldn't be the same and you'd lose the maximum potential you can get from these ceramic rings. Alternatively you could move them to New tanks and from existing tanks or filters to seed them and jump start the biological filter process! Good luck!

Yes, they can, but I wouldn't through a bunch into the water. Just like living worms it will make the water a mess. I only feed what they will eat in a couple minutes. The rest I pull out. As far as I'm concerned they are so much easier than the live ones.

Yes, you can. But it isn't easy. Either rinse the heck out of it (you will be rinsing away quite a few minerals as well, so be aware of that), and lower it in a scoop at a time. Or nearly empty the tank, putting the fish etc. In a bucket. Add product in where you want it, replanting as necessary, then refill. The first is easier, the second better, though difficult with larger tanks.

Yes, you can use this products with fish. This product will not hurt the fish. It is not intended for plant-only tanks.

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

Oh yes they can,the seal is very good. Items stay very fresh also. You would not be disappointed by purchasing these. This is an air tight seal.

I guess you could, but goldfish (from my experience) tend not to like small tanks, they produce a lot of proteins and small spaces don't agree with that, but I suppose if you flushed the water enough it would do alright.
