Went to the LFS store this morning at they happened to have the rock that I currently have in my tank on sale. Bought 15 more pound's and a nice piece of driftwood for 30 buck! Also cleaned and did my wayer change this morning and put in the new Aqueon pro heater I bought. Man what a difference. I set the temp to 78 and that's where it went to and has remained ever since. Definetly gets 5 stars in my book!
