Choosing phosban reactor for 250 gal tank?
 

I have a reef tank with lots of fish. Despite my best efforts, my phosphate levels are usually >1ppm. I would like to reduce this with a phosphate reactor.

For a 250 gal. system, what size and kind of phosphate reactor should I use? As far as I can tell, the only one readily available in Canada is the Two Little Fishies Phosban Reactor 150. It is suppose to have a capacity up to 150 gal. I don’t think this would be large enough.

Does anyone recommend a different brand with a higher capacity or should I try running two Phosban 150 Reactor’s together? Does anyone run more than one, and if so, do you run them separately or together as a circuit?
Tanks,

I run 2 in series on my large setup. (220g total)

I dont think the amount of reactors would have an effect, on a larger system you would have to replace the media more often though. I have a regular phosban reactor on my 225 and its working amazingly, killing algea like theres no tomorrow.

Go to J&L Aquatics & check out the Deltec reactors they have. www.jlaquatics.com

About 5 times the price(give or take) as the one he was talking about though.

I've been thinking of running two on my 90gal; one for phosban & the other for Purigen. I was thinking of running them with a MJ600 but a 400 might be fine & simply run them in sequence.

I'm running two on my 65 . One for Rowa Phos and the other carbon. I'm running with a maxi 400 in sequence. Seems to work well 0 ppm phos and good clarity on the water.

me too but on my 30

Precision Marine makes a substrate reactor which is the same thing as the TLF Phosban reactor but comes in two sizes and the larger one looks fairly significantly larger at 26" heigh with a 4" diameter chamber (the smaller one looks to me roughly the same size as the TLF). Although J&L doesn't list it on their site, I inquired with them a couple months ago and they can order you one.

But running them in series works too if you need more media.

I have two (of the TLF Phosban reactors that is), each running carbon on different tanks (for which they work really well). I have one of the first models and one that I bought a couple months ago. The new design is much much much better, so much easier to work with. The early models had a bolted flange, but the new ones have a twist lock. Changing out media on the newer model is a snap.

Though realizing DIY with acrylic is a little more involved than just cutting and gluing, seems a phosban reactor would be a relatively simple DIY project.
