jabeuy Posted December 4, 2014 Share Posted December 4, 2014 I have 36g all in one style tank. Currently I'm running some filter floss below the overflow and have a protein skimmer (tunze 9004). There's an unused chamber in the back which measure about 2.5 gallons. Would a refugium or some media reactor would be more effective at reducing phosphates? I've read on other threads that the fuge has to be some % of the display for it to be effective, yet I see many AIO tanks with just a small ball of chaeto in a media basket. Link to comment
clownfitch Posted December 4, 2014 Share Posted December 4, 2014 It takes a large amount of macro algae to make any large difference in phosphate levels. A reactor is the way to go on a nano. On setups with LARGE refugiums macro in conjunction with a reactor is common. Link to comment
rafastank727 Posted December 4, 2014 Share Posted December 4, 2014 A gfo reactor will do the best in reducing po4. I had a nasty green film on rocks and on glass on my 75 and within 2 weeks it was clear of algae with gfo. I still grow chaeto for copepods and etc. which is beneficial for the tank not for reducing nutrients. Link to comment

What I don't understand is the small fuges people run on small tanks like nuvos. Where they have chaeto in a small media rack. Wonder if that's mostly for the other benefits of refugiums.

Any experience with using gfo/phosban/etc. not in a reactor (ie. in a media rack instead)? Link to comment
rafastank727 Posted December 4, 2014 Share Posted December 4, 2014 Gfo needs to tumble to work effectively, so go with seachem phosguard. Link to comment
jabeuy Posted December 8, 2014 Author Share Posted December 8, 2014 Thanks for the input. Opted for a bag of phosguard, put into my overflow chamber right below some floss. Cost $5, so... thought I'd try this before anything else haha. Link to comment
