3000gph is good for the 100gal? Jeez don’t show me another design. Just kidding. But should I upgrade from the 1200gph to the 1900gph? I didn’t bring it with me to work, but I will have to go to a different lowes anyways so I can do it later if I decide to go bigger. I do think it will make for a better waterfall and if the filter can handle it with an increase in .4amps, whatever do it right? I am returning my 325gph to go with a 550gph instead for the fines, thou I almost want to go to the 700 or 1000 even, but I must resist.
And 2-2" bottom drains? I certainly dont want to spend the money for a 3" ball valve, but maybe do it completely separate with 2-2" ball valves. It may be overkill, but, at the same time it seems like a good idea to get faster drainage so I never clog. I ordered another box of 24 sos scrubby balls to have one complete bottom layer of them (99 balls). So now Ive spent about $200 on filter media. I did plan to do mine on the bottom and support the filter in cinder blocks or something so that I can get all the gunk out.

Not sure if my questions got overlook, but woud the 1900gph be better for me?

Assuming my 1200gph will flow about 1000gph with 2' head, It would have 4.2 minutes in the barrell assuming 70gal water in the 100gal filter.

Assuming a 1900 flows 1700 it would have 2.5 minutes in the filter.

Assuming 3000gph even at 100gal with no media it is only in there for 2 minutes. I know the logner the better, but also the more then better the falls so stick with 1200 of go to 1900 because of the head loss it will flow less anyways and give me a better falls. I got a sweet rock for the falls so I want it to be spectacular.

How about a plastic In-Basket? I just brought one home that was in the trash at work and it looks both rugged and functional.

An in-basket is where people, mostly engineers place 8 1/2" X 11" documents into for your approval or review. It is an office thing.

Thats a great idea! Cheap to, would I line the In-basket with liner or just put the liner between the basket and tub. DO they come bigger than 8 1/2" x11?
