bubbled forth the following:

We have a 6' x 18"(h) x 14"(d) tank with about 45 gallons in it. It
has been running with fish now for about 6 weeks.

That's a 78.5 gallon tank, why only 45 gallons of water?

Well, it is full to within 1" of the top. I have about 2" deep of
gravel, and I can only presume it is due to the volume of limestone
rocks that I have in there. But it only holds 205 litres of water.

Thanks,
