I have a 75 gallon with lots of rock(80ish lbs.) and 1-2 inch sand bed. It's been up since April and currently has two clowns. I realized soon after I filled it that it was too close to the wall. I use HOB protein skimmer. I just got a Fluval 70 and it wont fit. I figure it's better to take water out and move it now and fix my mistake before I fully stock it down the road. I don't want to hurt the clowns. If I remove enough water to slide it out a bit and then gently add water back right away, how much of a cycle am a likely to have?
