What Carbon Does Everyone Use?

[drw94]

Just trying to get an idea of what carbon people use in their SPS tanks. Can you please tell us your-
Total water volumn-
Is it used in a reactor?
What brand?
How much?
And current bioload-

Many thanks
Don

75 gallon,premium aqautics bulk ($7/lb),in filter sock on drain into sump,heavy load,1/2 cup changed monthly

[silentscream]

115 GAL system
3/4 cup BRS Rox in a TLF reactor
Changed every 3 weeks, bioload = low to medium

[reefgeezer]

75 Gallon/.5 cups BRS GAC

I use BRS rox carbon about 3/4 cup in a BRS reactor for a 120g system.

Am I using too much carbon? 1.5 cups in a NextReef MR1 reactor... 66g total water volume.

Edit: using Brightwell Aquatics Carbonit-P. Used the BRS calc and selected pellets.

80 gallon system using .5 cups of rox 0.8 carbon in a brs media reactor that also tumbles 3/4 cup gfo running a medium to light bio load.

[Reef Bass]

1 cup BRS ROx in BRS reactor for 150g system with light bioload. Changed when gfo depletes, roughly monthly.

KZ carbon
150G Net water
half a bag. for 30 days
passive.

Aquarium Pharmaceuticals/API carbon
75G sps tank with 20G sump
ran in a reactor along with GFO
dont know how much I run but I nearly fill up reactor

The $5.98 carbon at Walmart. I think it is called aquatech replaced monthly.

BRS Rox here

BRS Lignite. 1/2 cup used in a dual reactor w/GFO, changed about once a month when I change GFO.

Thanks for all the input. It is interesting to see what everyone uses!

[mrbigshot]

Aquatech (walmart) or cheap brs carbon. 5 tbsp in a single brs reactor. Changed every two weeks. I suppose I could go longer but I have to clean out the sponges in the reactor anyways

Rox.8 from brs 4 cups in 1250 gallon heavy loaded sps. Not tumbled but water slowly passes through

for what it is worth there was a nice chart/ study on carbon I found several years ago and pound for pound Api was the best. If cost were no object: two little fishies hydrocarbon was the best. I have tried a lot of carbon and really believe hydrocarbon is the best. You can buy cheap light weight carbon for a lot less but it is not as effective considering pound/cost ratio.
