My tlf phosban 150 came in. Just waiting for my gfo from bulkreefsupply. I have a 30 gallon tank, and a mj400 to power the reactor. How much (in Tbsp) gfo should I start with? brs recommends 1 tbsp per 4 gallons. Should I start here?

did you see an improvement in your tank after using it?I have been using the 4tbsp recommended by BRS without issue. However, I am doing so simply based on those instructions so if anyone has a different experience/reason, I would defer.
