Hi all, I have a bc29 that has a sand bed. I have been fighting hair algae and bubble algae for 6 months now. I have decided to go bare bottom and started removing the sand in sections during water changes. I normally remove 5 to 10 gallons a week. I have about 20 pounds of live rock in the tank. The tank is not fed, and I have no fish. I did have fish in the beginning but developed ick so my tank has been fishless for 10 months. I run ro water. Wondering how fast I can remove the sand safely?
