Hi, great information, this, for the most part, will be my first tank, my better half has had many fw tanks and bought a 75 gallon tall tank, we have a 42 gallon that I'm going to make into a sump/fuge, my current question is about water changes.
You mentioned that a weekly 10% change is optimal. What does that 10% account for? I think I remember rating the sump is included so Would it be 75+42 (117) so I would take 12 gallons out, or would I consider the sump only half full, (21), some in the pipes, (2) the tank is at least a 25% not water (58) total adding up to roughly 81 gallons so I would do an 8 gallon change.
Again I have never ventured into this, I'm planning on buying much of what is needed that we dont have as a suprise for her, so she might know I'm just trying to learn for my self to be prepared.
Thanks and this forum and this thread especially has helped a ton, I'm planning on printing it out to keep in the cabinet for an easy to grab guide
