This Leakender 2000. What chemicals is it composed of?

And for the cascade 300 filter. What kind is it? Canister, HOB? And where is the crack?

I have no direct experience with Leakender 2000, but a quick google gives me very little confidence in it...

There is very little information about available about it, and a lot of complaints about it not working.

In a case like this, depending on the size of the leak, I would just replace the filter. If you really want to keep the filter, I'd get some aquarium safe silicon.

Just my opinion, but I would not trust the leakender 2000.\

external over the back filter.chemicals are as follows:trichlorethylene, aluminum paste, isobutane and propane are the propelants. I have some white silicone caulking i used in the bathroom.

I would be very wary of "aluminum paste."

That's a pretty vague description, and a few possible meanings would be pretty bad for aquatic life.

Regular bathroom silicone isn't good for aquarium use because it has anti-mildew/fungus agents in it. For around $3-4 you can pick up a tube of GE silicone I for windows and doors from the hardware store or walmart that is ok to use in aquariums.

Or if the filter isn't that old, I may think about contacting the manufacturer about any warranty.
