Suggestion: Algae terrariums should not consume water when submerged

[Hexicube]

The idea here is to make it a trade-off. Instead of consuming water steadily and throwing out oxygen, the lower half can be submerged (at least 80% of the tile?) to remove the water cost completely. This way, it's a large investment of otherwise useful water (that you also need to prevent being used) and potentially also slower (but more efficient) oxygen recycling, but in return you don't consume water.

Doing a simple comparison, an algae terrarium currently produces 40g/s of oxygen while consuming 30g/s of algae and 300g/s of water. A single electrolyzer produces 888g/s of oxygen while consuming 1000g/s of water with the added benefit of hydrogen production for power. To match, it would take about 20 algae terrarium to match the oxygen output of a single electrolyzer while consuming 600g/s of algae, and 6kg/s of water. 6kg/s is massive. And, so is 6kg/s to 0 kg/s.

Personally, I feel like the overall consumption of water and algae should either be reduced as a whole to make large quantities of algae terrarium to be viable. Or, allow the algae to be self-sustaining only under the condition that it is surrounded by carbon dioxide.

I could of sworn I saw a dev do this (or at least try) in the initial twitch stream.

Yeah the algae terrarium now is consuming so much water, i think it will be good it only needing co2 and water (just like a Normal plant). The other problem is that the dupes will maybe collect the flowing water, and when this happens, the dupes seems like to be very inefficient. When you build lots of algae the dupes tends to be inefficient, they spend the whole cycle watering and putting algae on the terrariuns.
