Very easy, pump water into the chamber and exit back into your sump. You won't need a very big pump. You could use one chamber for PO4 remover and the other for carbon.

The Eheim 300lph pump will do the trick. Leave the dosing pump aside.
Yup - I agree - You need a slowish flow, but nothing as drastically slow as a dosing pump. IMHO I would use the dosing pump to dose something like Multi Vits or Trace elements etc..

You can do a great job with those things.

People must also remember that phosphate removers and carbon are very simple, water flows over and through it and it does its job.

One of the easiest and most effective DIYs that I've seen is the use of a cheap gravel cleaner, with water pumped into the chamber holding the media either open and stood up so that water simply falls out the top.

The mark two version is to get two cleaners and take the neck part off one to form a complete chamber to hold the media. A little sponge or filter wool at each end keeps it in place. :)

You do get the blank containers the same size as the cartridges, I use them and they work very well. They are clear plastic so you can see the media "bubbling".

Looks a great bit of DIY going on, to get the best out of a phosphate eactor only fill about one third to half full and then get the flow to "ripple" the surface of the media.

Just curious as to why you did it this way, as water always takes the path of least resistance.
Its not my thread so I shouldn't really reply here (sorry). I did it that way because of the way the item i was converting's natural flow was in the first place.

starts with abit of eheim 16/22 pipe (green flex) with a bit of 12/16 in side it with a 16/22 rigid pipe over the 12/16 pipe and a bit of 12/16 pipe in the over end and slots cut out of the rigid pipe that end too so that the water goes down it throught the slots in to the ROWAphos bubbling the ROWAphos then up throught a sponge in to the next chamber with ROWA carbon it kook like it could work well :slayer::slayer::slayer:
