Aeration in a planted tank at night.

Hint for the marine part:
Where might there be easy to observe marine life, high plant/macro algae density, fish, inverts etc is a temporarily closed system 2X a day? :rolleyes:Haha, Easy enough.:hitting:

pH goes from about 8 to 10 or a tad over that sometimes. Well, at/on most intensive areas but not all. Must check it out during night fishing.
Hopefully I dont have to jump into water at night,even shallow. :nono: :grinyes:

Shallow FW ponds with thick weed growth, low alkalinity will easily move 2 or more units of pH. That much I knew but so many variables influencing outcome as in nature. No two lakes are alike, etc.:)[/QUOTE]
 
look at it this way... if in nature somehow water areas usually end up getting more/replenished oxygen during the night then plants have probably adapted to make the most of that situation and would likewise benifit from similar setting within the tank.... what yall think about that thought?
