i just set my tank up Sat. i used about 10gal. or a little more of water out of a good tank and about 40lbs. of cured rock i tested my Ammonia today and noticed it was up.. could my tank allready have went through the cycle? i went to 2 LFS today and they both told me that i had to add fish to start the cycle.. i know that everyone says not to so i didn't.. do you think the tank could of cycled in 4 days?! would be great if it did.. ill just keep testing tomorrow.. if it has cycled should i do a water change before i add anything? i think ill get a clean up crew first..
