What would PAR be for a 20g long?

I feel so stupid for asking this but is there anyone here who could tell me at what intensity(approximately) would give me PAR levels in the 15-30 range?

My tank is a walstad setup so no co2 and no ferts. My light is the Fluval Plant 3.0. The intensity is currently set at approx. 25%. My plants aren't growing as quickly as they were with the T8 fixture I was using before so I'd like to find out where I should set my light to without it turning into an algae farm.

I don't have the money right now to rent a PAR meter. If I did, I wouldn't be embarrassing myself by asking this.

If anyone is able to figure this out for me, just let me know so I can give you any additional info you may need.
