Seeking feedback on plumbing plan
 

Even though I'm months away from moving into my house I have begun thinking about plumbing my tank. Below I have put together plumbing map for feedback. I have not yet decided on pumps but would appreciate your recomendations based on your experience.

Thats going to be one oddly placed overflow.

I was considering not using a traditional overflow but rather 2 - 90 degree PVC pipes at water level. Will this work or has it be done?

I think you will run into problems at the bottom of the tank as there is no water moving down there... everything is taken from the top of the tank and goes back to the top of the tank... I would make the intake for the CL at the bottom of the tank... and would be wary of a 90 for the overflow... as anything would be able to find it's way in there... JUST my opinion though

You dont have to have any holes in the bottom of the tank, most people only have holes closer to the top, as long as you have good flow and direct some water down you should be fine. But i still think a regular overflow is the best way to go.

I built my horizontal overflow after studying regular horizontal overflow boxes. The price of black acrylic led me to this design. It cost a whopping $3 to build and has been running on my 75G. reef for a year now. It is just over 12" long but because it skims the surface from both sides it has a skimming surface area of 24". This is the same skimming surface as two 6"x6" corner overflow boxes but without the loss of all that tank volume and without needing to use durso or stockman overflow pipes. To make it even simpler one could cut away those straining teeth and fit it with gutter guard but I like to play with my mitre saw :lol:
In my experience it is very successful and I would recommend it, or some variation of it, to others.
but that's just me.

Dale, I like it. What's the backside like, elbow straight, hows it's for noise?

At first it was a little gurgly but then it settled down and is pretty quiet.

Here's a pic of the back

Thanks Dale I like the idea. Couple questions...

1. Is the piping just painted PVC?
2. How did you determine the size v.s. your return pump?
3. How much noise does it make?

Thanks

Further to my question above, I have posted some pictures of the future location of my tank.

3. existing stand - do you think it will hold 700 lbs of water?

Hi Josh,

The piping is ABS. There is some debate as to its use in aquariums (fear of leaching something??) but I think the main reason ABS isn't used for potable water lines is because it doesn't withstand pressurization. The drain isn't under any pressure load though and my reefs been running for a year with it so... I will leave it to the debating society.
My returnline is 1/2" and my drain is 1 1/2" so it can handle the flow. My reef has a slow turnover rate anyways as it was set up for seahorses (they don't like high flow) and is augmented by a closed loop recirc system.
If you go through the link for the tank build you will see that I test everything in my garage first so that I can make adjustments if needs be.
It gurgles a bit but not that much. When the hood is closed it's silent.

I have no idea about the stand/table but there are two forces at play to consider:
The downward pressure
The lateral sheer pressure.
The downward pressure is pretty straight forward but the lateral sheer pressure is tricky. This is the pressure exerted as soon as the weight is shifted off its center of balance ie. if you bump up against the table. Most tank stands have cross bracing to withstand this pressure. I'll edit this post later with some things to look for when evaluating that table.
