Water change help

[Petergagnon1234]

I have a 12 gallon nano cube saltwater tank with 3 hermit crabs and 2 chroma. I am away every other weekend. I am unable to perform a water change until 2 weeks. Am I ok?

Sure, how much do you change?

 

[melosu58]

Two weeks will be fine.

As long as you change like, 30-40% that's what I do

 

[Petergagnon1234]

I usually do a 5 gallon change every other week

I personally change 5G (Out of 10G in my 14G tank after the rock and sand displacement) every 3 weeks

You should be fine

Thank you so much. I have been a little concerned with the frequent water changes because recently, all my stuff died. Everything just died . Except one hermit crab. I had 4 damsels a chromis, a clownfish and a mandarin. Everything died. Hopefully I won't have that problem again

That sounds like a lot of fish for a 12G tank. The mandarin probably died of starvation, they eat copepods and will wipe out a small tanks populations very quickly. They are usually recommended for larger tanks.
