Vacation and a pico tank

Hello, people on the salty side!

I have been considering setting up a pico reef tank (3.5 gallons) with just corals (no fish or other creatures). I know it's very difficult to keep a tank so small in balance. I will normally be able to keep up on water changes, but my question is, what will happen when I go on vacation? Will I need to have someone come by every day or every other day to top off the tank? I guess I'm just wondering how long I can leave the tank unattended.

Thank you!

 

I would invest in an auto top off. Great lid and light timer.

 

Agreed, an auto top-off or someone to top-off for you would likely be required.

With my tank, I could get 3-4 days before I had to top-off (sump level would fall too much), but the smaller the tank, the bigger the evaporation impact on salinity, so you'd want to keep up with it.

 

Thank you again, Teishokue and ryanr!! You are super helpful!

 

Yeah I tried the friend/family auto top off. It didn't work too well. "oh you mean I was supposed to add water? "
