Hi. Sorry to divert the topic a bit. I'm also very new in this area - juz 8 days setting up my tank with 7 guppies & 10 tetras in it. U mentioned abt changing 20% of the water weekly. Do u mean leaving the fishes inside while taking out the 20% water & adding fresh water in? Won't that cause a stir & freighten the fishes inside the tank?
How long can a 'clean' tank last without the need to chg all the water (100%)inside the tank, is a month time too long? Pls advise. Thanks.
