It looks like setting up my 55 gallon tank is on hold for a while. I filled it with water to test for leaks and all is well. Then I placed my prize piece of dead driftwood root that I collected in the tank to sink. It floats very nice thank you. It is too big to boil in a pot so I poured several gallons of boiling water on it before this. LOL Well, it has absorbed some water but it has not shown any signs of sinking to the bottom yet. I placed a 2X4 across the top of the tank to weight it down a bit. The tank has only water and the driftwood in it. I don't want to add substrate or anything until my prize piece of driftwood can be used in the aquascaping. No sign of brown water although the water is turning a little cloudy from just standing. I was hoping it would get water logged and sink on it's own. It's been floating for 5 days now. Any ideas on how long it will float? Any comments????
