Is no water change in 3 weeks ok? I'm going on vacation.
Im going out of the country for 3 weeks. I do a 20% water change every two weeks. Will it be ok for that extra week? I have my neighbor coming in to do daily feedings, check on things and add calcium/nutrients for the coral.
I have a 47 gallon tank with about 70 pounds of live rock. 2 clowns, 1 rock blenny, 1 firefish, 1 diamond back blenny, 10 hermit crabs, 5 snails. I have a small frogspawn, two duncans, one small leather and a tube anemone.
