GPH with phosban reactor

[Keith A]

I am looking into getting a phosban reactor for my tank to help reduce the P04 level. I have a 75 gal tank and a mag drive return pump that will cycle 1200 GPH (at 0 ft.). I have approximately 5 feet of tubing going from the return pump in the sump, up to the tank so I'm guessing my GPH is about 950ish (???). If I were to attach a phosban reactor to the to the tube from the return pump, does anyone have a rough estimate how much would it reduce the GPH from the mag drive? Would it be better to hang the reactor on the back of the tank and use a seperate power head for it?

definately want a seperate pump for it. You want a slow flow through the phosban reactor.... Just so the media tumbles in it....

I use a maxi jet 400 @ 106gph.
Surface of phosban should be lightly tumbling as stated, and be careful not to use too much, it can drop alk and throw everything out of balance.

hi Keith
we have a 210gal system w/ a lil fishies phosphate reactor...
we use a rio50 on the reactor and it works fine... its a tiny pump but thats all it takes for the reactor to do what it needs to do.

be sure to put a media bag over the return line of the reactor to catch any phosban that might get blown out of the reactor (even w/ low flow one will still have this happen)

good luck.

I think they recommend about 60-80 GPH max.

We're using a mini-jet 404 and splitting its output between 2 (two) TLF reactors (GFO in #1 / carbon in #2) and its more than enough to pump thru both reactors w/o problems....have the ball valve set @ approx 25% closed to keep the GFO at a nice 'rolling' boil so to speak....so far no issues, but use the plastic squeeze clamps to hold the lines in place on the pump and we're using 1/8" wide plastic wire ties to keep the tubing on the reactor barb fittings/90' angle boots... good luck...

Thanks for all the feedback. I already have a smaller power head (Aquaclear 201 with 126 GPH). Is that too big to use it direct or should I do what 918ReefCPL suggested and use a ball valve to reduce the GPH? I'm thinking of getting the single chamber reactor (Phosban 150).

[AZDesertRat]

The reactor comes with a ball valve to adjust flows.

Yeah, I gave GPH of my pump, but forgot to mention I've got it tuned down a bit.
I think best description is granules on top should be lightly dancing on surface.
I can't say enough to watch alk, and I've heard some say maybe even bump it up right b4 reactor install.

OK. Thanks for all the info. By the way davocean, nice looking tank on your thread.. Got any bigger pictures?
