I was wondering if anyone thinks it's possible to build a closed loop system with a mech filter, chem. filter and UV sterizer, and heater built in, using pvc. I know you would be killing a lot of organisms in the tank, but just was wondering if I could make one? I know you can buy one.

I suppose you could, but I would think you'd need a SERIOUS pump to push through all that, especialy when the mech filter starts to catch detritus.

Yea you are right. Maybe take out the mech filter?

I think I would. Got a diagram of what you're thinking about?

lol no, right now I just have it in my head, I know I could use 2 to 3" pvc for the tubes, I just dont kow how I would run the pvc carring the water through the pvc tubes. Also how would I cap the tops of the tubes but still be able to remove them to replace things like carbon. Sorry if that doesnt make any sense

Hmmm, seems like it could be a lot of maintenence. Do you not have a sump?

I will have a sump. this goes with my surge device we talked about.

I cant belive im about to use my favourite word here.:roll:

Run "Reactor" chambers in series. Im here all week ok! lol

You wouldn't want to plumb all that directly into a closed loop, there will be WAYYYY to much flow for that stuff to work properly. You could "T" off and put that stuff on its own leg, but even that would be challenging to get the flow right. You would want to buy gate valves (NOT ball valves) if you decide to do it that way.

reactor chambers?

Like this Two Little Fishies Phosban Reactor 150 (Saltwater Aquarium Supplies > Filters > Inline/ Specialty > Phosphate Reactors ) (http://www.marinedepot.com/ps_ViewItem.aspx?idproduct=TL4311). They are used to force water through a medium giving you better contact.

speaking of closed loop systems does anyone have any good plans for them or know where there are some?

tank, pipe, pump, pipe, tank, da_da! :huh: bang your very own closed loop..lol

hey i just offered an inline solution - I didn't see a pump value , he cause have been using a powerhead for all i new..lol
