carbon & Phos ban

[Firstman]

How long should I run my carbon and Phos Ban before I throw it out?

[jennabee]

For the average marine fish aquarium, carbon will last 6 weeks. Reef tanks produce more organics than fish-only tanks, so 4-6 weeks is a workable limit. If the water is not mechanically filtered or the aquarium shows signs of nuisance algae, you will need to adjust the useful life or increase the amount of carbon.

if you are using actual phos Ban then it does not leach phosphate back into water so you really don't HAVE to take it out. but it will stop absorbing once it is at capacity,, should give you an idea on the container

nice job of the webster honey.

I replace my carbon when my tank starts to smell, which is about 3~4 weeks. As far as the phosphate remover I'd perform weekly checks and when the P04 levels start to go up it's exhausted.

Thanks for the info. Tex.

you two had me a little confused there for a minute :)

most people use carbon for 2 to 3 weeks and phosban for 2 or 3 months.

ok good to know

I change both once a month. I also buy them in bulk so if they still have some capacity in them at least I don't waste as much money.
