Carbon & meds
How long does it take for carbon to remove the meds from a tank? Only, being a bit distracted this morning, I dosed my tank with ich meds without removing the carbon. I realised about 4 hours later and removed it then. Is it quick, or does it take a bit of time? Anyone care to hazard a guess? Ultimately I just want to know how likely that the full dose I put in this morning is still a full dose now? (150ltr tank, 3 fancy goldfish).
Before people say I should have used salt instead, I'm going away unexpectedly tomorrow for a couple of days, and can't keep an eye on water parameters, or dose the salt gradually as required. I've used the meds before on a different tank and they worked brilliantly.
