Received a response from PolypLab (posted below), it took about 2 days which isn't bad. Their explanation makes sense as I'd rather not strip the water of the aminos and RS colors supplements I'm using, so I am employing the carbon for a few days (just did a water change) then removing. Thanks all who replied and happy reefing!
Hello Steve,
There is no detrimental effect using activated carbon at all time. Activted carbon is part of the trick for a succesfull reef aquarium.
By nature, activated carbon remove organic compounds from water. At Polyplab, we focus our approach on the global ecosystem of the tank. The bacterial aspect and amino-acids supplementation being second corner stone of our system after coral nutrition.
Promoting the use of activated carbon on a long period while using acids, fuel or colors would be a waste of these 3x products since carbon would suck it out of the tank. This is why we recommend using activated carbon only few days a month.
Ideally, activated carbon use with a ULNS or probiotics system should be done just before or after a water change. This will remove unwanted organic compunds, polish the water (better colors) and reduce smell that can be annoying. It is also require form removal of

Of course, no need to buy bags of it and timely use of carbon dont require you to buy a lot. [emoji106]
