2 things I want to ask.. I have a penguin 150 bio wheel filter on the tank and I am adding flourish excel ferts and I was wondering if the carbon in the filter cleans all the ferts (impurities) out of the tank or not.. Because I would hate to know that all the ferts I have been using so far were a waste..
And also, I think I am going to start DIY yeast c02 tonight because I have a Hagen bubble ladder and tubing and an empty Juice bottle and I was wondering if I should take out the bio-wheel or take out the whole filter when I start injecting c02 because I heard that bio-wheels are bad for tanks with c02..?
