FRAG 85.3 exact gallon size

[Anthrax15]

I am reading mixed answers on how big the display and sump are in total for the FRAG 85.3. I have estimated it at around 60g after displacement for sand/rock but have read some posts say it is closer to 80g. Trying to figure out the size for dosing purposes.

If it’s just for dosing purposes you should probably start out using the lower number, and then see how it effects your tank, then adjust the dose higher/lower if needed.

An exact number isn’t really needed
