Need tank drilled

[Brian Ward]

Ok I edited my profile, good call.

 

The drilling is going to be done on the 90g that I am actually picking up this weekend. It is reef ready so I know the bottom isn't tempered, depending on how much room I'm working with I might do 1 of 3 things.

 

1 - Just run a pipe up the back and use a U tube as the return into the DT

2 - Drill the bottom and run the return like that

3- Drill the back (maybe in the overflow maybe somewhere else, maybe more than one spot)

 

Actually, the bottom probably is tempered. They drill the holes prior to tempering the bottom. I would assume that the bottom of the tank is always tempered. Also, if it's reef-ready, then it has an overflow with a drain and a return hole already in it, so returns aren't a big deal. The only thing you'd want to drill for is a closed loop.

Wow I didn't know you could temper it after drilling. I thought it was the type of glass and two laminates, not arguing I just didn't know.

 

Yea I realize it has an input and output in the overflow. The system I am going to do though is going to have a fail safe which needs to be in the overflow. I figure use one existing hole in the overflow for the main durso, and use the second (normally the return hole) for the fail safe. That's why I was contemplating how I wanted to run the return line because it is going to be the most flexible in terms of placement. I think I might just run a U tube over the tank into the DT to avoid having to drill and all that. This also will allow me to go straight up with the return line rather than running to across the bottom to the overflow side.

 

This all also depends on what the setup is like. I talked to the guy last night and we are trying to decide on a pickup day, I haven't seen the tank in person but it comes with a canopy and what not (easily cut) so I don't know exactly what I'm working with but I have a pretty good idea.

I think you're going to find that there isn't enough room in the overflow for another pipe. Also remember that you will end up with stupid fish in your overflow that you have to get out somehow. I would drill the back and add a second or third durso to set up your failsafe.

 

Oh, and tempering is a heat treating process, not a laminate.

Oh yea I never thought of that. Yea I do like the look of drilled tanks, looks cleaner IMO. As far as the fail safe goes, do you think its worth making that one into a durso as well? I was just going to do a regular PVC pipe with an screened opening, hopefully it will increase the sound of water flowing in there so I will know my main durso failed. I'm hoping one backup will be sufficient, I am also banking on the idea of my main durso not failing =D

 

Oh and my bad I was thinking of safety glass, although I think they might use tempered glass in safety glass to reduce the risk of shards? Either way good call again.
