    How often do you replace carbon and phosphate media? Can you specific which type of media you use (seachem matrix carbon, phosban, phosguard, rwaphos, ... etc.)?

    Once a month; carbon (activated lignite) and phosphate media (granular size) from bulkreefsupply.

    You change phosphate media once a month too? I thought they can last longer than that?

    Both depend on you PO4 and DOC load. They could be used up in a day if high enough, or last a year if low enough. You can't tell what your demand is going to be off of some one else's tank, you just can't.

    I mix the two together so if the carbon goes, the gfo has to go as well.

    I see. Are you using a phosban reactor? If so, will adding carbon into the reactor one a month works, too?

    i change my carbon 1 a week (i only use 3 table spoons each time) as for as rowa phos appx every 3 months.

    I try to change out the carbon every three weeks but it winds up being closer to every five weeks.

    When I ran phosphate removers I would change out closer to five weeks

    Running mine in a DIY reactor, which sits in the sump. I couldn't build two chambers in it, due to the height of the sump so I went w/one and stuck both in.

    I mix em together too. Probably change every 2nd water change so about every 3-4 weeks.

    Phosban every month, I run Black Diamond carbon passively in my sump and change it about once a month too.

    I feed a lot so I use a little more than the gram per gallon on the gfo, more like 1.5g per gal.

    Gresham's right on though, it all depends on the system.

    I change my rwaphos every 3mos cause verytime I messured my phosphate it always read 0ppm. Carbon I alway change it once a month.

    I change my carbon twice a month :)

    GFO, carbon? I guess I need them to change them :p

    I never thought of mixing them. Its ok to open the bag of chemipure and mix it with the phosban that I use in my reactor?

    I mix some black diamond carbon with TLF phosphate media in a TLF phosphate reactor, changing it out once a month. I put the carbon on the bottom half, and gfo on the top half (to keep it from being 'pulverized')

    Welcome back, Art.

    I wouldn't. The stuff in Chemipure is a fairly small particle size.

    Do you think that chemipur is worth it or do u recomend a different brand of charcoal

    I just use bulkreefsupply carbon and gfo. I do the opposite of Art and put gfo on the botton and carbon on the top in a phosban reactor.
