Hi I'm new here, I posted one thread in the intro section.
I have a 3 gallon tank, whisper filter & air pump, LED light, whisper heater (78 degrees), and of course a male betta fish (edward).
I have had the fish and tank for 2 weeks now. I've done 2 30% water changes, and 1 90% water change. The reason I did 90% is because I didn't want completely new water for the fish and bacteria.. stuff... If I'm doing it wrong please correct me. (Water is treated before and after changes)
I'm semi lazy and have read a few things saying 100% water change every week if the fish is in less than a 5 gallon tank (yahoo answers). Wouldn't that shock the fish too much? It just seems more harmful doing a complete water change every week versus a percentage.
Thank you and any tips would be appreciated.
