Skimmer Sizing Recommendation

[aray]

Looking for a recommendation on Reef Octopus skimmer sizing. Waterbox 150.4 rough dims are 48x24x22, actual total system volume is 114 gallons (88.5 Display and 25.5 Sump). Currently running a Reef Mat 1200, I would prefer not to over do it and be able to leave some nutrients in the water. I'm currently looking at the 2 sizes listed below, open to other recommendations as well. My skimmer chamber water depth is only 8.25", the Reef Octopus line was the only brand I was seeing that came close to that recommended water level

Classic 110INT 4” Internal​

• 60 gal (Light)
• 90 gal (Medium)
• 130 gal (Heavy)

Classic 150INT 6” Internal​

• 110 gal (Light)
• 150 gal (Medium)
• 210 gal (Heavy)

Personally I would go with the larger of the 2. Skimmer recommendations for gallonage is usually optimistic at best. I dont know if you took those numbers as a direct quote or you typed it out but they look reversed as the light bioload should be the higher gallonage. Typically the true numbers are about 1/4-1/2 of what they advertise.
The 150int should read
210g (light) but actually 110-150g
150g (med) 90-120
110g (heavy) 50-75
It should also be noted that the bioload refers to fish and mobile inverts not corals. If the reef mat is functioning at optimum this will affect the skimmer performance. I still say the larger though as you can tune the skimmer to pull dryer and less from the water.

Yes I flip flopped them on accident, those numbers are reversed. Thank you for catching that
