Tank Upgrade

The Tank Upgrade is an item added by Hatchery. It comes in 3 tiers and can be inserted into the Methane Digester Generator or the Fertilizer Mixer to increase the size of their internal tanks.

Tier 1 increases tank size by 2 buckets, Tier 2 by 4 buckets and Tier 3 by 6 buckets.

If multiple Tank Upgrades are put in the same machine their effect do not stack.
