I can put within a freshwater aquarium???

The tip of the thermister is stainless steel so it shouldn't rust or bother the fish.

The module is not waterproof, but u can put the probe in the tank and it will work fine.

The probe only, of course... but keep in mind the readout is ONLY in Celsius, NOT in Fahrenheit!

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.

Yes! That's where you should put it; that's where I have my 29-gallon tank. Works just fine!

It works well in my mind Fluval SPEC Desktop Glass Aquarium, 2-gallon. The heater itself need to be submerged at all time.

You would put it on the inside tank's wall, close to the bottom gravel. Beautiful.

From what I understood/remember, you can put it directly into the tank, in the water. (I have mine in a hood) You could also lay in at base behind tank or "rig/tape" to top of tank outside/back perhaps?

Yes you can but rinse it really good before you put it in there. And it's more brown then black, which really bothered me, so Fyi in case you want a certain color substrate. You can definitely add more but rinse it very good or it will make your tank look like crap and clog your filter.

you can but i would use the model RP90 with built in uv sterilizer for freshwater it will help a Great Deal with parasites such as ICK.

It would probably work well for insulation. I would just worry about the weight of the aquarium.

You can place media anywhere as long as it fits within the space you plan on using it for. I owned an aquaclear 20 but I'd highly recommend to keep the sponages at the bottom and bacteria on top. I don't use carbon in my filters since there pointless so either add more bacteria media or this media to see how it goes. I would recommend go use this stuff in canisters only in my opinion which is what I use it for.

Yes - if you get the Hagen Fluval 25wt submersible heater, it will fit in the out-put portion where the little pump is. The Fluval heater is square"ish" with a slimmer design than any traditional heater I have seen. The only drawback is it only keeps my tank at 76 degrees and for my goldfish that is fine, tropical fish would be better kept at 78-80. This is a pretty little tank and mine is doing great. It arrived well packed, with no damage. Hope this helps.

It would have to be a pretty huge aquarium. There are probably cheaper alternatives more suited for aquariums. This is a whole house unit. Installing it would probably take avery experienced aquarium tech and/ or a plumber

The length is approximately 4 1/2 inches. As long as your aquarium is at least that tall you should be fine.

I would go something a little bigger with more surface area at the base. A 20-30 gallon aquarium would work well.

Nope. After having it forma months i came to the conclusion. This one is for freshwater aquariums.

I imagine that you could put the fish inside, but then you would not be able to see them. Where the water falls it's too small for fish-plus it has little holes for the water to drain to the bottom... Hope this helps...

I think that you can, but I don't know that I would. I have a 3 gallon tank and it barely keeps the water in the 70s F. I worry that burying it under the gravel would inhibit the heat from spreading throughout the tank. But I think you can try it without any dire consequences. Just keep an eye on the water temperature, and if it is too low for your fish, dig it up and stick it to a tank wall.
