Skimmerless 20 gal ?

I was asked by my younger brother if he were to set up a 20 gal salt water does he need a skimmer if he is only stocking with a few fish and live rock?

A skimmers purpose is to remove protein based organics from the water column before it enters the nitrogen cycle. The nitrogen cycle is what feeds algae growth. It is also what can kill your coral/fishes.

With a 20 gallon, I would strongly recommend it, since its a small tank it's more likely that your parameters could fluctuate pretty quickly.

I've heard of people running nanos with no skimmer. I have a 150 so I'm not very familiar with smaller tanks.

Over filtration is much much better than under filtration. I understand that a skimmer is expensive, But so is constantly replacing dying critters.

It's generally not needed to run a skimmer on a nano tank. Personally, I have an overstocked 20g reef with a 10g refugium growing grape caulerpa and haven't had a positive nitrate reading in about 3 months. Once you move to larger tanks a skimmer gets to be more of a priority.

I have a 75 gal now and I have a skimmer ,
It seams to be very effective by the color and smell of the skimate . Lol

ill be the one to tell you, no you dont. as long as you over filter the water like a refugium or a strong hob filter, your good. im running a 36g bow front with just a hob rated for 75g and it does WORK. i just keep up with weekly water changes and filter/media swaps as long as you follow a strict routine your golden.

true, im maybe contemplating a nano skimmer for my tank but so far everything is happy and healthy. i plan on maybe 5-6 fish tops and corals too so far its going very well.

It's definitely not a bad idea to have a skimmer on that tank, but it's not necesary

It's not needed. I have a 20 with no skimmer, but do have a HOB filter w/ two floss pads and Purigen. I also only feed every other day.

What are you using for filtration?
