Quick question...

So ive been reading nonstop through various books, and am juggling the ideas of all the types of filtration.

It seems that the most popular is the Berlin system right? Alot of sand and liverock to biologically filter - and then reinforced with a protein skimmer? Or did i totally miss the mark in my reading?

Yes, that would be correct large amounts of LR and LS per G of water with a skimmer and timely PWC and of course, a properly stocked tank, your good

You can have too much lr/ls as well though. The general rule of 1-1.5 lbs per gal and a sand bed of 3"-5" is recommended.

Yes, LR and a good skimmer. Many people use a sump, which helps with lots of things, including allowing you to use a larger skimmer. because of this, most people prefer predrilled tanks.

A true DSB is generally no longer recommended, so don't go over 4-5" unless you know the risks.

Basically a DSB beyond 5” runs the risk of becoming toxic more than one at 3”-5”. It can still be done but is considerably more work and has to be watched carefully.

I think the jury is still out on the DSB debate. There are alot of folks out there that have never had problems with them, including me.
