If you put a divider in a massive tank the fish still has the full volume which is better than not having it
If you take a cup full of poison and drop it in a small tank volume it could kill the ray out right
If you take that same size cup of poison and drop it in a river it wont affect the fish at all I think the word is dilution
It doesn't take much working out that if you have a bloom of ammonia nitrite or nitrate it will have a bigger impact on a 2ft tank than a 6ft tank
Come on this is basic fishkeeping a larger volume of water is more stable than a smaller one
100% correct on every point, no argue about that! But we do work daily to avoid this, no matter how large the tank is? If there is a 20 gallon tank with 100nitrat, you have to change 10 gallons to make it 50.. If you have a 1200 gallon tank, you have to change 600 to make it 50.. I dont see the difference(exept more water)..
Offcourse the **** hits the fan faster in a smaller tank, but if you did your homework, its not a problem.. Main filtration to avoid ammonia and nitrite i do take as an "offcourse not".
