I want to use a 1000L of water for my tank, can someone please confirm the size in square feet that I should make the GB if I is 1'-0" deep. How many fish should be in that tank. |

The answer to this "length of string" question lies in how much much water you are willing to pump out of the 1000L tank, if you're going to employ a sump or not, the type of media and its water holding capacity etc... Draw a plan, do the maths, search the forum... then post questions. |

A gravel:water ratio of 1:1 is widely used... so a GB (or GB's) with dimensions capable of holding 1000L of gravel at 300mm (1'0") depth. A gravel:water ratio anywhere between 2:1 (2000L gravel:1000L water) and a low of about 0.6:1 (600L gravel:1000L water) will work fine... just remember to stock fish in ratio to the gravel, not the water. |

I'm running around 20 sq foot with 10 - 20 fish, which seems to work well. |
