| Re: Bio Balls, is this really why???
I bet their nitrAtes are high and they compensate that by doing very large and frequent water changes... OR.. like the Baltimore aquarium, they have HUGE remote DSB that harbor the de-nitrifying bacteria...OR... they have really high nitrAtes and don't worry about them since it is FO system.
It would be interested to know their entire process.
Keep in mind that our goal as reef aquarist is to keep the nitrAtes at 10ppm or less for our systems and although high nitrAtes are tolerated by fish, it is still stressful to them and best to keep them as low as possible.
