Another benefit to less food's being offered is that fishes that might not normally forage along the bottom will do so once they are de-programmed that food's will not be coming thee or four times a day.
Overfeeding is a great problem for many and they may not even realize it.
All of my fish forage the tank, half remain foraging when they see my shadow get near the tank.
The reason I started this thread was sort of a soft approach to high nitrates.
I hope for more reader input for sure.
Myself and many others in the forum have replied to many threads of others complaining of high NO3 levels.
Always trying to help with advise and suggestions to reduce nitrates.
Primary high Nitrate problems stem from? (Not in any special order)
2. Too may fish / large bio-load.
3. An all in one fert product / KNO3 cannot be eliminated or reduced.
4. Not monitoring water parameters @ all.
5. Lack of water changes ( not a controversial subject in this thread please! )
6. Nitrate in one's tap water.
7. Tank maintenance, vacuum, change filter media, etc....
Inspiration for starting this thread was around fish waste and how it effects our aquarium.
Most think of fish waste as little ringlets of poo that float to the bottom and create mulm.
Mulm is a slow degradation process that takes considerable time.
Uneaten food and plant matter also contribute to mulm buildup.
The plant matter and uneaten foods seem to dissolve/disappear quick though.
The fish poo seems to be a much longer process to dissolve and break down.
Regarding the article I posted 25% of fish excrement is solids.
We all notice this and it is for sure a visual.
We tend not to consider the liquid waste that is 75% of fish waste released right into the water.
A visual representation is not really there, we don't get to see it accumulate on the substrate.
I guess I am trying to bring a realization to the forefront.
I noticed this in the early 80's when I had a grouper and a large trigger in a SW tank.
As they swam by you would notice what they expelled that was not solids.
Reminded me of the haze you notice while driving on hot asphalt north through the desert toward Mexicali.
We typically don't see this with most of our freshwater fish being much smaller etc...
