This may sound silly, but this is my first large tank. I've only had nanos up to a 37g now. What would be a good amount to change (every 2 weeks at what % ?) Also how do I siphon out that much water and add that much water w/o making a big mess. Up to now, I change 10g in my 37g and only did 5g changes in my 20g which didn't take much work.... I'm just thinking about how to accomplish this. How do you all do your changes and where do you go with that much water? Do you use a regular siphon hose? Thanks in advance.
