sump plans for 370g

  • We are currently upgrading MFK. thanks! -neo
haha theres not much i can really do right now until i get that egg crate.. i could finnish all the piping under the tank but i dont want to start until i get the pump you know...
 
Egon and dxdx are giving you great advice on the sump design, so I'll keep my suggestions towards your pump...

Based on the first pic you posted it looks like you are planning on getting a Reeflo Hammerhead Gold? If so, I think that's way too much pump for your setup.

1.5" drains can handle about 1,400GPH each, so your max capability on two is about 2,800GPH.

A Reeflo Hammerhead Gold does about 5,000GPH at 6' of head pressure, so your drains are not going to be able to handle all that flow...the Hammerhead will overpower your drains and suck your sump dry. You will definitely have to go Mike Tyson on those overflow teeth, but in addition to that, you will need larger bulkhead fittings/drains if you decide to use this pump.

If you want to stick with the Hammehead, you are going to need to expand your drains to 2", and even at that you will probably still have to valve the pump back a little.

I would personally recommend going with a smaller pump (the Hammerhead is a gigantic beast). I would recommend going with the Reeflo Super Dart Gold that does around 3,200GPH @ 6' of head on 185 watts

or

Run one Laguna Max Flo 2000's in each sump (each Max Flo 2000 does 1,360 GPH @ 6' of head on 78 watts, for a total of 2,720GPH on 156 watts if you were to run two).

I personally prefer the idea of the submersibles since you don't have to worry about leaky seals and you have a redundant system (two pumps)...in case one fails, the other will still likely be going strong. If you go this route, you should still plumb your sumps together.

Hope that helps you avoid my mistake (I had a Hammerhead gold that overpowered the teeth on my three 8" x 12" overflow towers):

or... what does having more gph do for my tank?
will i get better filtration with 5,000 gph flow or...
better with what aldiaz33 recommended? and external pump is the only option becuase i already drilled those holes and as you can tell by my sump i dont plan on patching anymore holes....
wow am i pissed that i didnt drill the right size holes....:irked::irked:
 
or... where can i find a place that can build me another overflow? because i might as well just go with what i planned because i literally built my entire tank around this pump...
which dissapoints me that i didnt get the drain size correct....
 
It's no big deal, you can make this thing work easy. You don't have a pump yet so just plan on getting a smaller pump. another thing you can do (I did this on my 180 build) is run your return through the top away from the overflow and use the return holes inside your overflow as drains. I actually run all my acrylic tank returns this way, through the top of the acrylic tank.
- giving you a little extra drain capacity.
- the pump will return above the waterline so no chance at creating a syphon when the pump/power fails causing your sump to overflow.
- the filtered water enters the tank on the other side of the drain so your getting a good turn over through out the tank.

Remember, all filtering does is shortly postpone the inevitable water change. Set up a trickle system and you don't need as much of a turn over, you wont need a huge pump of fancy wet/dry crap. Because you will constantly be doing a water change.
 
im currently looking at custom overflow boxes and i can get one for around 100 bucks... looks like im going to be installing another one on the opposite side.

im assuming i should put two 1.5 inch drains there and one 1.5 inch return?
 
hold on im going to draw up something tell me if this could work?
going to take around 30 min to draw...
