So at the moment I have a sumpless 40g breeder and am planning on making a stand to hold another 40g breeder under it as a sump. However I was wondering if I would be bale to make the stand to hold a bigger tank if I plan on upgrading for the future. Basically im asking if build the stand 48 x 24 using rocket engineers template, will it be able to hold my current setup of a 40g breeder on top? Ive already been told how to build the stand to accommodate the 40g sump and am just worried about the extra width of the stand being a problem.
