450 gallon Project - looking for some help...

[Orthopod]

I picked up a used glass 450 - 72 by 60 by 24 for a great deal. Some issues that I am trying to work out:

1. It's predrilled at each corner 2 inch bulkhead holes in opposite corners and 3/4 inch bulkhead holes in opposite corners. There are some small chips in the drill holes that I'm going to try to fill in with glass filler and then seal the bulkheads with silicone. Hopefully that will work. Let me know your thoughts...

2. Filtration - here's where I need the most help. I was going to try to use 2 old tanks for sump and Refugium below the tank.
I have an old acrylic 65 and a glass 75 that I was going to try to turn into sump and Refugium. I also have 2 fx6s that I was going to add in. Not sure how to link the 2 tanks for sump and refugium but I'll give it a whirl.

3. Stocking - Assuming I can get it up and running, I was thinking of making this a ray tank - but that's farther off.

Here's a picture of stand and tank prior to set up.

Wow, that looks like a fantastic tank!

You can definitely attach two tanks together for a sump. All you would have to do is put a large bulkhead or two on each one and link them together with some pipe. You can also use a water bridge if you would like to try something like that. What I would recommend is that you have one tank on the floor and then move the other tank off the ground and drill it to overflow back into the tank on the ground. Since you have a 65 gallon acrylic tank it will be easy to drill and have it set up to overflow back into the 75.

I can't wait to see this think set up!

Haha I saw that tank on Craigslist.. Was about to buy it but you beat me to it the footprint on it is amazing

That's a nice tank, with top euro brace. From what I've seen, that's great for rays.

Why not use the existing bulkheads for drain and returns? I suspect that's what they were intended for 2" and 3/4", drains and returns, respectively.

Anything aside from rays in this tank is a disservice to the tank haha. Great pickup. I agree with the above. The 2" can be plumbed with a simple elbow and the 3/4 inch returns are perfect for loc-line bulkheads and knuckles.

I would also consider not doing the refugium. It is not nearly as needed and or effective in a freshwater application. It would be useless on tank with a heavy bioload like rays.

If I were to setup you system with the parts you describe I would do the following:

2" overflows from tank
65 gallon tank for 32" filter socks.
65 tethered to the 75 via x2 2" bulkheads
75 chocked full of K1 for a moving bed reactor
x2 Laguna 2400 pumps (already 3/4")
return to tank x2 3/4" bulkheads, loc-line knuckle, loc-line hose and tip.

That is a relatively cheap way to do it with the gear you have. You can get considerably more complicated or advanced from there.

Thanks for the input.

Here's the chip issue that I'm trying to fill in:


Also was considering investing in something like this since in a large wet dry since it's on sale if it will be better for the filtration

for the chip on the glass just silicone the bulkheads in and that'll do the trick.
dont need to do the extra stuff with fillers and what not as the silicone will do
that for you.
