Determining protein skimmer

Hi everyone,

How do you determine your skimmer size? For example, if you have 100g DT, and 40g sump, do you go for 140g size skimmer? or just 100g size?

 

you want the skimmer to be rated for the total water volume of your system. and honestly you kind of want it to be overrated.

 

Thank you dowtish

 

Always use the heavy bio load rating of any skimmer because the vast majority over populate their tank.

Bio load is determined by how much O2 that volume of water can hold. If all the volume is circulated, then all the volume is available to the inhabitants.

But when you calculate bio load... or how many fish you want... you have to go by ACTUAL water volume. You do not have 140g system... I would be surprised if you have more than 100g of ACTUAL water in your system. That is what you go by.

 

Thank you Powerman. The 100g, and 40 sump is just example. I have 180g with 60sump. From what I research, a lot of people recommend about 25-50% of your DT for the skimmer to handle properly. So, I am looking at 200-225g skimmer.
