Ok, so Im getting a big tank... well not as big as some, but big for me. It will be 72x24x24 with a 50x18x17 sump. Im upgrading from a 48x18x16 which currently houses IT's, various bichirs, spotted gar amongst other things. I liked the idea of a sump, for increased water volume as well as increased filtration volume and hidden equipment. i've never had a sump before so im not entirely sure what to put where. Will also have a large external. My big question is about substrate. I dont like the look of a bare bottom (on a fish tank anyway) although I can see why others do it. What I want is sand. Ive read snippets here and there about pool filter sand. First off, is all pool filter the same? i have seen stuff on ebay that is around 1mm particle size. Is this the norm? Ive read that pool filter sand is heavier than normal sand- big fish churning up a sandstorm is in the back of my mind... Anyone know where to get pool filter sand in or near plymouth (uk) Oh, and does anyone know how much a 6x2x2 tank weighs? just the tank, not with water. thinking of carrying it into position. When it arrives (late jan/early feb) ill get some pics going. Thanks for the help
