Okay, I am so confused. I just got an Aquapod 24 today and want to get it up and moving. I have the live sand and a nice bit of live rock. I have Instant Ocean salt and have been told conflicting things: I can use tapwater if I treat it.
hi and welcome

i just set up my 24G AquaPod, so we'll be about a week apart in caring for our tanks. i was also told by my lfs i could use tap and a buffer, but after reading everyone's advice here, i ran to the store and bought distilled instead. if you already have your LR though, how are you keeping that? it can't get dried out. here's my very new advice (because i already had a set up problem)...buy your water, mix your salt and let it run for a day. then test your specific gravity and have your lfs double check it (if you are using a hydrometer) before you put in anything. i had a very faulty hydrometer and had i not double checked it with my lfs before putting in my LR i'd have wound up with nothing but base rock.
