I have a 5 gallon pico reef I am just starting. It's finally done cycling and I have started stocking it.
First off, do you want to have coral or just a fish? For a fowlr (fish only with live rock). You will need the following:
I'm going to assume you are going with a 10 gal.
•A tank.
If you want a clownfish you need at the bare minimum a 10 gallon. But you have to research the type of clown you will buy because I believe some get larger than others.
•Live rock!
10-20 lbs for a 10 gal.
This will be your main form of filtration. I know it seems strange to not have a filter for the tank like you have on freshwater tanks, but that's the way it works for saltwater! I have a small HOB filter on my pico reef. Guess what is in it. Not a filter cartridge but live rock rubble! The only reason I'm using the HOB filter is because I need water flow- which brings me to the next thing you will need-
•Power heads!
You will need to have power heads to create water flow in your tank. You want the water to be flowing all over the place in there. It is to keep the water moving around the live rock and so that you have movement/turbulence at the surface to promote gas exchange. Plus sea creatures come from the ocean and they need the current so they feel at home.
•Oh! Sand!
You can buy live sand which usually isn't really live. There are lots of different sands you can use.
•Heater
You want to keep the water at the proper temperature.
•Hydrometer or refractometer
This will measure your salinity. Go with the refractometer if you can. They are alot more accurate.
•Thermometer
Self explanatory
•Saltwater mix
There are different brands you can pick from.
•Fish Food
Also self explanatory.
•A lid
Not necessary but helps cut down on evaporation.
•a light
Doesn't matter what kind unless you want coral.
•A SALTWATER TEST KIT
This way you can cycle your tank and keep it healthy for your livestock.
Hopefully this helps you get started!!
