I dump mine through the weir when the lights are on.how do you administer the Vinegar? are you using a dosing pump or just straight into the sump?
It's definitely worth it. just be sure the vinegar you're using is 5%. Ramp up the dosage slowly, dose ONLY when the lights are on and make damn sure you have lots of flow in your sump. Low flow in your sump will make slimy shit grow in there, I've had it and so has Lesely.And how did your dosing regime go? was it worth it?
I'm looking at doing it to bring my Nitrates down
