down with a cold... but pics will be coming....
filter setup:
mechcanical:
4 3 inch diam overflows from tank to open filter box ( 175 gallons) where the water runs thru a long series of mechcanical filter media and dumps into a 400 gallon sump. Sump has three separate 4000 watt heaters and controllers. The water is then pumped up, by a 3/4 hp march pump ( 55 gpm), to the UV sterilzer and drops thru two parallel barrels with bio balls and flows back to the tank. The bio balls provide degassing and bio filtration.
From time to time I run a 7inch dia x 30 bag filter to polish the water. The bag ratings run from 100 micron to 1 micron. Intial flow is about 60 gpm and bag change when pressure get to about 7psi. This really cleans up the water as the main filter only goes to about 100 micron. The main filter was finer but it needed cleaning everyday....now its about every 10 days...just rinse the media out and put it back.
anyway thats the basics....i will get some pics online.
bio filtration
From the sump water is pumped continously ( approx 2000 gph) to an overhead barrel filled with bio bale and bio balls. When the barrel is full it siphons itself empty back to the sump and cycle repeats.... also at about 500gph sump water is run thru charcoal ( 7 lbs).
