Hmmm, if I am getting this right, a certain percentage of the water from the overflow is diverted to ONE of two places. The goal is to rely more...equally on passive nutrient consumption within the fuge, which would potentially result in an increase in macroalgae growth and continue that nutrient cycle.
Channel Schematics gathered from video:
1. From overflow to fuge (you do not explicitly state where it goes from there but I assume it is back to the DT)
2. From overflow to protein skimmer and back to DT
I guess I am wondering if the potential increase in efficiency is significant and otherwise worthwhile.
I know that there are some sump designs where a percentage of water goes from Overflow to Fuge and then back into the DT and another percentage goes to skimmer then DT. Those designs usually require an atypical manifold set up and pump placement.
Also, Some people have simply changed the typical set up based on need. For example the aqueon proflex model. Most people I see using this put the skimmer in the last compartment and attempt to keep water level steady with an ATO. This way it does allow for biological filtration first.
Although, I cannot imagine the need for an entire sump that is potentially more effective at growing macroalgae. Most people I know have relatively small sumps, and those that have HUGE tanks have macro for looks not actual nutrient export.
Either way, I am interested to see what your sump design looks like and how it really functions!
