As I was looking at some tank pics I noticed that in many of them the tanks have some algae? growth all over the back of the tanks, are we supposed to leave that stuff there? Just wondering for future purposes...
Also, I just ordered 45 Lbs. of pre-cured live rock which I'm planning to fully cured in my 55 gal
. (yes it's empty except for saltwater) and have another 40Lbs or so in another tank that are cured. My question is, when the new rock arrives, should I also add the rest of my other rock or wait until the new batch is cure before adding the old ones?
thanks in advance for you advice
