Fudd it. Throw in the towel. This ain't for you.
Or get the biggest tank possible. The bigger the tank, the more mistake you can make and its more forgiving to errors.
Really. I don't test and don't wc on my 9 footer. Given it's only a few weeks old. Unless something die.
I'm more of reactive instead of proactive. Yeh I know it's bad practice and lazy. Bigger tanks can tolerate all the imbalances.
Can i add copper without any problem?
I set up a 20g qt tank and added a live rock from my display. It has been a few days and 3 fish are happy and eating (thanks @Apon)
I wont return rock to DT.
