55 gallon quarantine: 5 packets or 6 packets?

[KittenFishMom]

I decided to do a quarantine trio treatment on my 55 gallon tank.  It was my native tank. I never treated it because I was thinking about releasing the fish at some point. I have added non-native plants, so it is a non native tank, so I think I should treat it, in case I want to add any fish in the future. I also decided to toss the killer killifish from my QT into the 55 gallon tank to keep simplify life.

My question: For 55 gallons, should I use 5 or 6 packets of Maracyn and ParaCleanse?

If you take into account substrate and plants your tanks closer to 50 gallons than 55 so I would put 5 packets in a more effective way to treat a large tank is to add the paracleanse to food he's a recipe

When I treated a 55, I took out 5 gallons of water first. I don't know your set up, but that might work to make the math easier.
