I'm getting ready to dose prazipro and I added my rock and sand without measuring what was left smh I have a 29 gallon tank, 30 pounds of rock and about 30 pounds of sand. thanks
Can’t. Already added fishThat’s cool, @Seadoc .
As an approximation, I was going to say, mark your water level with a piece of tape on the outside of the tank. Siphon out water into a gallon jug, or even a 5 gallon bucket. Measure how far down the water level drops. And then calculate how much water is in the tank using that method. Note that less water by volume could be down in the tank with the rocks are, but that’s why I was asking for a photo. Lol. Best wishes.
thank you. Going to try now
