| Re: Does anyone have one of these or something similar? Yeah the Hydor Mini is safe to bury in the gravel, it's mentioned in the instructions. I guess after the gravel and decorations the water volume will be down to about 3 gallons, but I'll have to measure the actual volume because I'm not really sure if this bowl is 4 gallons or not. My guess is that it's slightly more than 4 gallons. I may mount the Duetto Mini in the horizontal mode on the bottom of the tank and rotate the water outlet 90 degrees upward. |
