Also can’t I just make a giant canister filter and use it as a sumptwo questions
I’m new to this hobby, so why are canister filters not good for reefs
and what would u recomended for a sump for a 5 gallon nano
Do I need two pumps for a sumpCanister requires frequent cleanings to prevent trapped food and wastes from adding to the nitrate level.
Once matured, Rock surfaces, especially those that provide a ton of surface area are the best filters of all.
I use canister simply to deploy different media’s like carbon and gfo only.
A sump is not mandatory but is nice for placing equipment. The other great benefit is that they allow for “bigger water” which is much easier to keep stable. You can place more rock in a simp if you wish to add “surface area” for beneficial bacteria to grow.
I have a small 3.5 gallon tank I can turn into a sump5 gallon is so small which every month you can slowly do 1 gallon water change or have 10 gallon sump . To be honest the bigger sump u have the less water. Change u will need bc u adding more water volume to ur tank
