Hello - I'm in the process of changing my filtration in my 90g from hose-only to mostly PVC. I like the idea of the cleaner, more hi-tech look, but I also believe I can save some space down there.
My biggest problem so far is attempting to plumb my 300w hydor inline heater directly to PVC. I discovered that the threads are 1/2", but you can't fit a 1/2 NPT fitting onto it, because the nipple is fatter than the actual threads. If you try to put a 3/4" fitting on, to get it over the threads, you won't be able to screw it into the 1/2" threaded shaft. I just got back from the hardware store, where I spent a good 45 min messing with different pieces, but nothing seemed to work.....yes, I asked for help, but the guy didn't know...said it was a weird-sized attachment.
Here's a look at the heater and the nipple itself:
Here was my original idea, but I'd like to reserve these brass fittings for the direct connections to the filters. I want the heater and UV to be plumbed without using filter hoses:
A picture of the whole thing:
I did manage to find the fittings for the Turbo Twist UV, as they just required a 3/4" bushing and reducer to 1/2" slip. Piece of cake, b/c it didn't have that long nipple on it:
Here's my assorted pile of PVC stuff. I'm going to start putting it together and see what I come up with, but want to figure out the heater issue first.
Any ideas from the PVC gurus?
