I'm currently building a 20g sump for my 90g tank and I was wondering how full i should fill it. I know I'm not supposed to fill it full to the top but I'm not sure to fill it 2/3 or 3/4 etc.
I'd also like to know if it is better to use bio-balls or a filter sock. I've heard contridicting opinions about both.
Is it ok for a protein skimmer to be in beside the return pump, or should it be farther away from it? As you can probably tell, this is my first sump that I have ever built so any help is gladly appreciated.
My plans for the tank is for now a FO, but after the tank has been set up for awhile, I'm going to slowly convert to a reef.
