Drilling Aquaclear Filter for bulkhead: Questions

Hey DIYers,

I'm thinking about modding an Aquaclear 20 Filter case (The one that comes with the fluval edge) for my Marineland C160 Canister filter, which has 5/8 ID tubing.

Now I'm thinking about drilling holes for a bulkhead in the filter, like such:


I've never done anything like this before: how should I even approach this?

Would I use a bulkhead w/ hose-pipe adapters for the out-take side?
If so, what sizes should I use?

How should I modify the in-take side to work with the canister?
From the video, it seems that he used a reducer that screwed into the already-existing hole. Unfortunately, he quotes 28-29 and 32 cm for the hole sizes, which can't possibly be right.


I've been doing a bit of digging and I think I know how I'm going to tackle this. If anyone has any experience with this DIY mod, please do chime in.

In-Take Side
So from schematics posted online, I have concluded that the pump-hole in the aquaclear20-case (the hole where the supplied pump goes) has a diameter of ~1.12'' (see diagram 3).

This makes me believe that I will be able to use a 1/2 inch Bulkhead(which requires a 1 1/8'' hole, which nearly corresponds to 1.12'' inches) without modifying the in-take area of the aquaclear20 casing too much.

From there, I plan on screwing a 5/8'' (Barb): 1/2'' (NPT) Tube adapter into the bulkhead.

This should be the right size for my 5/8 ID marineland C160 tubes, and I'll use a hoseclamp to keep everything tight.

Ah crud. I just realized that I have to find a way to attach and seal the bulkhead to the supplied in-take tube of the AC20. Any suggestions lol.
-As of this moment, I'm contemplating using a 5/8'' (Barb): 1/2'' (NPT) adapter on this side too, putting on 5/8 in tubing and stretching it over the AC20 Intake Tube.
Outlet Side

I plan on drilling a 1 1/2'' hole into the bottom of the aquaclear 20 case, in a similar place to the modified AC20 in the video above.

Next, I'm thinking of using the 3/4'' Bulkhead and screwing in a 5/8'' (Barb): 3/4'' (NPT) Tube adapter.

With this, I should have a modified AC20 for my marineland C160. In theory, not only will I have a high filtration rate, but I should also be able to use the AC20 media bay for either more media, or as a location for my nano heater.

What do you all DIYers think?
