Filtering strategy

  • We are currently upgrading MFK. thanks! -neo
i said 50%+ b/c he stated himself that he was over feeding but w/e to each his/her own.
 
Let's say, I spill 8 Oz of hard pellet food. Every time I feed the 2 Oz , required by the fish to eat.
So I have 6 Oz of hard pellet food uneaten, and very slowly soaking up water. It will take about 8 hours before any of it is decayed into ammonia.
So in a 75 gallon display, being filtered at 750 Gph. Thru a 300 micron sieve filter. What percentage of 1/16" food pellets. Are still going to be in the aquarium water, and able to be decayed
When the 8 hour time it takes the bacteria to start breaking the food, begin.
 
Surely any debris in the sieve are going to leach ammonia in to the water passing through it
 
The beauty of the seive. All the debris is pushed out of the flow of water.
On mine the angle is quite steep. Most of the stuff "rolls off" into the dry below.
 
Should help quite a bit as long as you remember that 60% of ammonia released by fish is through the gills and urine, if I remember correctly,
 
Well then this method should work quite well for me. The fish's respiration and urine will continue on the nitrogen cycle, while removing the solids, I can compost into manure, and have another usable product for my garden.
 
It has some potential. Their is not a lot of information about sizing guide lines. My main concern is how bad will the holes plug over time .

It may be prohibitively expensive but you could set it up like a multistage filter with sieves of decreasing hole size. It would still eventually clog but this would substantially increase the unclogged life of the system.

What you could use is plastic and a CNC laser to pierce a hole of various sizes. This could be done very easily by running the same grid CNC pattern but adjusting the laser focal point size and dwell duration. I have some experience with lasers and have burned pin holes through half inch plastic with a diy rig and commercially available laser diode. Then half inch stuff makes a bit of a mess but you could easily get away with very thin material that would reduce time, cost, and increase the uniformity of the holes.
 
Interesting idea.
So far. The 300 micron screen has only lost about 5 % capacity. I did have to baffle the slot. As the far left side had the most flow.
I am also hoping that the slipperyness of a bacterial colony will help sluff off debre. If it jams up with 300 micron. I could use 350, or 400.
prehaps. Then let the bacteria fill in the holes. I have tooth brushed it twice in tha last 4 days, with good results. When I get a continous dribble on the screen. I think the baffle in the slot will help some.
 
Still going, have too clean every 2 weeks,20161023_130809.jpg
Cleans up easily.20161023_132053.jpg
The filter floss breaks the water tension, on the back side of the screen. Which helps separate the debris from the water.
