PhosBan reactor

Maybe you had to much flow through the reactor.

Has anybody built a DIY PhosBan reactor? It is basically just a container to hold the Phosphorous removing media while water is pumped through it. I have considered the idea of building my own.

Should be easy to build.Water flows from bottom to top,need a sponge on the bottom,then media,then sponge for top,then lid and exit fitting.

I'm running rowaphos in a phosban reactor, using a mag pondmaster (rated for 150gph). I've got the valve at about 60%. You only turn it so the top of the media looks like it's simmering. Just a slight waving motion at the top 1/4" of the phosphate media. I got rid of my monster hair algae problem with this setup. Trust me, it was BAD, since I was cycling liverock and turned on the lights almost right away... won't do that again lol

as for rowaphos vs phosban, advanced aquarist analyzed them, and found them the same pretty much. There IS a ph drop if you run your ph at around the 8.9 range, but if you run at about 8.3, then you probably only will have a 0.1 drop for a couple days.

Be careful, you can shock your corals with the sudden drop in phosphates, these things work so well. You can go from 0.5ppm to 0.0ppm in an hour. And measuring phosphates with a kit is pointless, since they don't measure organic phosphates, which is what most forms of nuisance algae utilize. Kits measure inorganic phosphate, which ends up precipitating with excess calcium anyways.

Ah....maybe I did have too much flow then. I'll have to try it again.

Thanx and cheers,

I don't think so. I ran a MJ 1200 on mine too, and if I remember right I had the valve wide open. The tumbling action of the RowaPhos came up the chamber by only about 2"-3". When I first fired it up I remembered thinking...."That's it?". If anything, it seemed it needed more flow. Maybe it was because it was RowaPhos, which is heavier/denser than PhosBan.

Cheers,
