68G cube becomes a 95G Reef :)

Never seen an overflow done like that! Not too invasive and looks cool too. Guess it can't be married with a Herbie really...that method brought me TOTAL silence when I finally got my gate valve perfect.

Yes it can. You need a second hole though that is just a bare pipe extending up just above where the PVC overflow skims water. So it will only kick in if the water rises up too high in the display. Just like in a normal overflow box except this emergency drain is separate from the main overflow.

Does that make sense?

Basically the emergency drain can be anywhere as long as it leads back to the sump and is above the water level of the main drain.

It has been done by a guy on RC on a 180G tank (I think). He says its dead silent and he has a coast to coast overflow. Not really seen in the tank.

I wish I had the second hole! That is my favorite way to plumb a tank by far. It really is dead silent.

The lights.



I just made a simple box to retrofit lights I already had. Dual 400 watt Metal Halide and 2 - 24 watt Actinic T5's.

Overkill for a shallow tank but so far so good. I love them and my corals really seem to be happier than ever. I am running the 14K bulbs 8 hours a day and Pure Actinics 12.

Originally I hung the fixture from the ceiling but I felt uneasy because it is a bit heavy and the ceiling is concrete. Getting a good anchor in it was hard. Oh and ceilings are 14' tall in my place so the cables were really long and just didn't look right.

I rigged up a way to use the fixture I built though in a unique way. I will post pics soon of how I did it. I absolutely did not want a canopy this time.

Anyone have any ideas for reflectors to replace those ones? It would need to be something that has the same footprint to fit where those ones are. They are not great and I want to chnage them eventually.

Yeah I was referring to your lack of a second hole sorry should have mentioned that. 14 foot ceilings does make it tough. can you mount the canopy to the wall so it cantilevers out over the tank? I was going to do this but the wife vetoed and made me go the fixture route...

Oh ok...I misunderstood.

No I don't want to drill onto the walls. They too are solid concrete and then finished with a thin coat of a nice concrete that crumbles really badly when you drill them.

In the first pic you can see a plam tree. That thing is 10' tall. So gives you an idea of the height.

I will get pics of what I have done with the light tomorrow. I think its ok but am looking for new ideas.

Is this similar to how some people are using a T near the end of their drain line to get air out and hopefully keep everything a bit quieter?

Advice?

Red is where air would be escaping the drain.

[GreenSpottedPuffer]

So if that would work ^^

Would this work just the same? Anyone know if this is how "T"'s are used to keep things quiet going into the sump?

I really can't remember but I know its something kind of like this. Or is it pointless to have both the "T" at the top of the drain and near the bottom?



I wouldn't mind getting this glued tonight if someone knows...

I wouldn't use the crooked pvc pictured in the drawing....
