No prefiltration, clear water.

Thought I would take a end on full length tank pic showing you can have pretty clear water without any form of pre filtration through 5' of tank water. No socks, filter wool or roller filter here. Yeah I know, I have some diatoms and a bit of GHA here and there but neither is a problem as Mr Sanja says.

I use Chaeto as filter floss

I dont even use that or anything else as prefiltration.

Skimmer, rock, heater, return pump, dosing lines, probe holder, and carbon reactor, all thats in my sump.

Water is crystal clear.
