How Much Gravel Should I Buy

[chilledtim]

Hello all, how much gravel (in Kg) should i need for a 90cm long, 30cm wide Tank?

Is there some sort of calculator online?

I've always read to put about 1lb per gallon. So that would be about 0.45 of gravel per gallon.

You want about 2inches of gravel at least. So for example for my 36" 125Litre tank i used 25Kg of gravel
