Yes, tis' the season for ich - we have it too! I am sure we will make it through though. Because of this, I am raising the temp gradually. My question is this - I have had my 100 watt heater for my 26gal bowfront in my new Bio-Wheel Marineland filtration system. So, the housing tank for the water and filter has the heater inside it as the water flows through. (I couldn't get the heater to do well until I put it in the water of the housing tank) Is this ok? Or at high temps am I killing all the bacteria in my bio-wheel? Can I keep it this way long term?
