AGA Megaflow w/DSB

[PaulB]

I was planning on adding a 5" DSB to my new AGA 180 gallon, but the
overflows have three rows of slots to admit water. The bottom row is only
4" above the bottom of the tank, so a 5" DSB would submerge them. This
isn't a major problem in itself, but does anyone know if it will reduce the
capacity of the overflow? It is only rated for 600 gallons/hr as is.

you can shape your dsb to not cover those slots an even sand bed is no fun anyways :D

To OP

Trying to understand the description > "Slot" < mean.
Does the slot refer to as port or round hole where water either go in / out?
Or a partition or chamber where water flow in/out?

If slot is refer to as PORT or Hole, you can use a PVC to match the diameter
of the innner size and make the neccessary extension above 5".
- Export / Import - Use inner measurement.

If it is a partition, please explan or link to the specification of that
item.

I mean the slits in the side of the plastic overflows housing that the water
flows through.

Here is a picture of the overflow:

Here is how it works:

The bottom inlet is the one I am concerned with.

I will try leaving a depression in the sand near them, but depending on
currents it might be difficult to keep them clear.

after things settle down itll stay clear though some sand will make it thru the slots,
expect to be cleaning it more often while things get settled in

It would seem from the pictures that the top overflow is not capped.
I reckon that the top inlet would take any extra water that was blocked
from the bottom inlet by the sand.
I don't own one of these though so you would be able to figure out
better than me if this extra water over the top inlet will create any
problems.
Also on a side note over sizing the plumbing on that stand pipe would
allow more flow through it.
Even if the bulk head/ tank fitting is the same size as it is now,
having larger diameter plumbing for the rest of the standpipe/drain will
still get you 30% or more through it.

It should be alright. I am thinking of cutting some extra slots in the
overflow though. I don't think it could hurt.

Ok, got the picture and see how it work.
IMO, I would simply block it and have the middle and top for inlet instead.
Later on when your sand seattle, I would still block it or cover it. The
reason I say that is regarding like worm and any janitoral critter that
might climb into the opening and get trap. You do not really need the bottom
portion. Any lite sand or debris particle or nutrient can be carry by
current and draft upward to the mid and top inlet. So again, lower portion
of the inlet is not necessary in my opinion. The lower portion may give you
problem then good as due to trapping and getting more fine sand into the
filteration area. Do you get my point here? Normally, overflow should be
ontop or top-edge where it can clean / skip surface area. Some may also have
the mid section but not or rarely bottom portion where water flow into. If
you still want the lower portion, you will need to do some maintainence.
Meaning, you will need a schedule check if any critter get trap on the other
side of the overflow and see if the inlet is trapping or clogging with
something that may decay in due time.

Sounds sensible. I will look into that.
