Bottom Drain

[jjkon]

Hi everyone,

I have a question for everyone. My bottom drain lid is 1/2" from the bottom of pond. If I were to raise it to 3/4". Will this increase the water flow from the bottom drain to the settling chamber(vortex)? Thanks in advance for all the repsonses.

Yes and no. This, like many things, is a relationship. It's relative. If the pump is pulling the filter chambers' water level down then raising the lid increasing the gap, (sometimes known as gappage) may allow more water to flow through being filtered. You are looking for the sweet spot where flow is maximized but is still somewhat sucked in, forced to hurry into the drain pulling LaCrap along with it.

be carefully, while raise the lid to 3/4 will increase the water flow but it also big enought to allow little fish to get to the filter and get kill.
