I would imagine these are probably overkill.CreeksideBrewery said:I will have the sump divided into the following sections:
1.) Water delivery from overflows with filter socks installed on each pipe.
I have heard that it's kind of a PITA to maintain them. My theory is that if you can make maintenance as easy as possible, it less likely to be put off or avoided.
In any event, hopefully you will have them set up in hanger holders - so that there is a way for water to bypass should they become full/clogged.
I'd skip the carbon ... limited usefulness and has to be replaced often to really be effective. Doing regular partial water changes is good alternative.CreeksideBrewery said:2.) Mechanical & chemical media stack. Sponge seated on top carbon bags.
I plan on using multiple layers of Poret Foam (sponge) in varying densities for mechanical in the sump for my 100 G - a stack consisting of two 1" thick 10 ppi (coarse) layers, followed by two 1" thick 20 ppi (finer layers)
It's supposed to be the bee's knees - lots of surface area and and largely self-cleaning.CreeksideBrewery said:3.) Biological media. I'm thinking K2 media.
All kinds of alternatives ... I'll probably use lava rock ... because it is cheap and I already have quite a bit of it.
A mag 24 will flow less than it's rated capacity after accounting for head and plumbing loss, so I would guess: not overkill.CreeksideBrewery said:4.) Return pump.
Does this setup seem reasonable? For the return pump, I'm thinking a mag 24 but that may be a bit overkill even for 300ish gallons.
Example: At 3' of head, that 2400 gph flow drops to 2000 gph.
Largely your preference/your call.CreeksideBrewery said:What should I use for the substraight? I was thinking CaribSea Dry Aragonite Special Grade Reef Sand.
Personally, I don't like fine sand because I find it hard to vacuum without sucking up the substrate. I think I would prefer more of a large grain sand/very small gravel - something in the 1/16" - 1/8" range.
I'm currently using large gravel (up to 1/2" 5/8" rounded or so) in one tank, medium Black Diamond blasting media (sand) in another (hate it), and some small angular gravel (around 1/8"+) in three other tanks.
The large rounded gravel lets too much debris fall into it's depths off the surface, the Black Diamond is too easy to suck up, and the small 1/8" gravel is just about perfect ... debris mostly stays on the top of the substrate and it is easy to vacuum out of the tank.
I have 1/8" stuff in the tank that I keep a pair of Julidochromis transcriptus in ... the male is only about 2 1/2" long and has absolutely no problem pushing it around to dig holes and build bowers.
