i appreciate all your hard work, and thinking of us on top of that.
i was already subscribed to all three packs, so having one megapack is definitely convenient.

It does not, it's in the infrastructure tab.

Does this require the new DLC? I cant seem to find the substrates that you made.

thanks, i really liked the new substrate system but the options were too few hence i wanted plenty to choose from, now there are plenty of options for salt, fresh, cold, warm and even modded content like terrariums^^

This is really a game-changing mod - being able to customize tanks to this degree is really going to liven up peoples' aquaria. Great job on this!

you select a substrate and just click on the tank you want it in
