water changes??

It really annoys me as it depends what angle you look at it from, if you shine a light on it or not. It's just too open to interpretation to be accurate.

I read something funny about it last month on MFK : the guy said to ask a girl to look at it since they have better color vision, or interest...

I do 75% a week with pre treated water.

Ha ha. It's good, better than the strips but it's not "marine biologist" accurate.

50% once a week regardless of Nitrates you still have hormones, urea and poo in there....and Bigger than 50% WC are fine if your BB is maintained and is not killed off most BB is on a surface not free floating
