80% to 90% water change so I can move a tank.
Is this going to screw up my biologicals horrendously or am I safe doing this.
I have (want) to move my tank from a kitchen counter to a stand, but to do this I am going to have to empty out the tank down to about 4 or 5 gallons to be able to physically move it. It is a 16 gallon tank.
so I will have about 4-5 gallons in the tank when I move it, and leave another 2 gallons in a bucket and another 2-3 gallons in the canister filter.....I guess now that I typed it out it doesn't really seem like I am taking TOO much water out.
