[i have crabs]

i was doing some tests on the other tanks last night so i checked for nitrate in the cube and over 25ppm has built up since last sunday, so i guess i was right that rottin sand and dried live rock would kick up a cycle in a hurry,i havnt even bothered to take a few scoops of sand live sand from another tank yet but i should probably get on it,ill maybe wait another week and do a huge waterchange which will give me a chance to try and slip a shim under the tank and even it out a bit
