What is this?

[lorenk]

I went to look at a tank for purchase and they had this item. The woman did not know what it was (the tank was her ex-husband's).

PVC looks like 4"...for size reference.

what;s inside? looks like some sort of filtration device?

Coil denitrator. Maybe. See how much tubing is inside.

 

[lorenk]

It's glued shut...so no way to tell.

Maybe that's what it is Danny. It doesn't look like the typical DIY plans, but who knows.

Ya good call Danny... That would be my first guess...

What's that home improvement show where they bring out the weird tool and they make guess at what it is?

Anyone use a denitrator on their tank?

The shape is probably due to a custom fitting around a sump or something.
