300 Gallon Custom Aquarium – Filtration Overview and Wrapup

This is part 7 in a series of videos about
my new 300 gallon tank from Custom Aquariums. I’ll link to a playlist for the project down
in the description. This is kind of just a wrap up to show a few
things that I didn’t get a chance to highlight as I went through the project. And some of these things I couldn’t really
show until they were up and running. And then I’ve made a few changes between the
planning stage and the implementation, so I’ll go over those as well. I guess it makes sense to just go through
the flow of water from the tank and into the filtration and back. That starts at these overflows, and you can’t really see them too well from
the front so here’s a better shot from above. These are an invention that Custom Aquariums
came up with, and they call them H2Overflows. They’re a nice alternative to a typical weir
that you would see in most drilled tanks. You get a lot of skimming area but with a
pretty low profile. You can hardly see them in the tank, especially
if you have the back painted black like I do. They also have a nice cover screen that keeps
large debris from clogging them. These flow into the Stealthbox, which I showed earlier but not when it was
attached to the tank. I have this setup with plumbing inside to
silence any water noise and it seems to be working well. The box has a cover which also helps. Then that runs down into the stand, and this has changed since I last showed it. I replaced the black ribbed pond tubing with
braided tubing. I got a comment about how it had failed on
other people, and honestly it felt a little thin to me, so I figured I’d rather be safe than sorry. But to be honest, this was kind of a pain
to do, and I probably should have just hard plumbed
the whole thing. I’ve just always avoided having anything but
tubing running through my walls. I don’t know why that matters to me. But it’s done, and now all of the tubing on
this whole project is braided, which is extremely unlikely to fail. And here’s where it comes down into the sump. That’s basically the same as before just with
different tubing. The first chamber has two big filter socks
and then the water passes into the second chamber, the baffle tub, which has a bunch of media trays in it. My first tray has some poret foam of increasing
density, then my second tray has some pinky filter
floss and some polyfil, This is not that dissimilar to what I’ve always
run in my canister filters. Then I have several trays of biomedia. This is Seachem Matrix in these nice zipper
media bags, which makes maintenance really easy. I’ll link those bags below, and if you’re still using loose biomedia you
should really pick up a few of these. Then I did make another couple of changes
to the sump. One is that I added another connection between
the baffle tub and the reservoir tub. I had these connected with a 2 inch PVC line
that you can see in the background, which was plenty of flow, but it was causing the water level in the
baffle tub to be too high, and the reservoir tub to be too low. This new inch and a half line keeps them closer
to even. And I could have done this with fewer parts
but I kind of just went with what I could buy at the store. And then another change I made is that I moved
the pump from being external and in line, to being inside the reservoir tub. It still connects to the return lines the
same as before, but this way I never have to worry about it
leaking. Moving back upstairs, the return lines connect to the tank via these
Siphon Stoppers, which is another Custom Aquariums product. The advantage they have over normal returns
is the two angled pieces at the top. These will be exposed to air once the pump
stops, which prevents a back siphon that could overflow
the sump. It’s just another nice safety feature. Another thing I haven’t shown yet is this
valve. This is what allows me to drain the tank in
a hurry. It’s connected to the custom one inch hole
that I had drilled in the bottom left corner of the tank. I can just turn this valve and the tank starts
to drain down to the basement. And if I want it to go even faster, I’ve got it running through this 1600 gallon
per hour pump that I can start with a remote control. This was all in place on the old tank but
now it’s even easier. And the last thing that’s still a work in
progress is the lighting. What you see here is the Current Satellite
LED that I’ve been using for years. It’s a 4 foot light, which is actually kind
of nice because it keeps the corners in shadows. It looks really dark on camera but it’s a
pretty cool effect in person. Then this is a very similar light, it’s a 4 foot LED from Fluval, and it’s controlled by my phone via Bluetooth. Like the Current light it can be customized
to just about any color I want. And then this is what it looks like with two
of those 4 foot Fluval lights in place, which was my plan all along for this tank. But honestly it’s just way too much light,
even when set very low. It looks great here on camera but in person
I think it’s just too much. And the fish absolutely hates it. So I’m just going to keep experimenting. But overall, the project is pretty much done. I’ll keep you guys up to date as to how it’s
going. It’s been a lot of work but it was definitely
worth it. Thanks again to Ted Judy and Custom Aquariums, thanks to my wife for putting up with this
crazy hobby. And thanks to all of you for watching. Until next time, have a good one.

  1. Looks awesome! I "overkilled" my 75 gallon with a pair of 3/4 siphon stoppers and an 1.5" h2overflow. Custom Aqauriums is great

  2. Awesome setup. But why dont you have the fittings pushed all the way into the hoses? You are only using half of the barbs on the fittings.

  3. The sand you picked brings out the fish perfect. It contrast it. Great choice. Lighting is perfect too. Now looking into changing things on mine. I like the look a lot. Decor is on point. Great job Steve.

  4. Good choice on the tubing Steve. I’ve also had the ribbed tubing fail on me twice. Like all the changes and improvements you’ve made. It’s always fun to trick out a filter system. 😎👍

  5. Love it all! Only question I have is those overflows. Great design but the GPH doesn’t look enough, how much water are those overflows taking in? Hard to tell watching this video. Maybe they’re bigger in real life?

  6. Beautiful Umbee, how big is he? I'm thinking of going overboard with one fish too and get a 120 for a Red Devil by himself
