Do you use GFO?
 

I'm actually wondering more who doesn't use GFO. For those who don't know, GFO is granular ferric oxide used to absorb phosphates. Brand names such as RowaPhos, PuraPhos, PhosBan, etc. I'm referring only to the RUST RED stuff, not the white stuff.

Multiple choice if needed...somehow.

Dangit, I screwed up...meant to have the YES options asking how you run it, REACTOR, in a FILTER (like an HOB power filter), or PASSIVELY (in a bag in the sump say). Please comment. :)

I run mine 24/7 in a reactor.

yes, 24/7, I run it in a phosban reactor, change it out every 3 months :biggrin:

yes....I run a phosban reactor......change it out every 2 months approx.

24/7 in a reactor; change approx. every 2 months.

Yes, In a Reactor. But I usually lack in changing it. Maybe every 3-4 mos. Thx for reminding me, I should change it tonight.

in a reactor, mine needs changing too. in the process of ordering some up from bulk reef.

24/7 in a reactor. Changed every 6 weeks.

Used after 2 month of starting the system but not anymore. So where should I vote? - No or Yes?

^ No, you choose not to. :)

In a reactor, changed once a month.
