Think this setup will work with acrylic tank? (Overhanging sump)

[Fitz19d]

So I wanted to run this 110 as a inline tank that i could offline easily. (Pump in 125 sump into the 110 acrylic). The overflow bulkheads are set back a bit further, I was always told acrlic needs total support , so how then would someone normally run a bottom of tank bulkhead anywhere because at best you skip the area of the overflow?

Went with this which is as little as possible overhanging so I can run pipe straight down into sump. I suppose I could try to wedge a bit of 2x4 or something underneath the "wings" of the tank on either side of the overflow.

Also, may have been uneven surface on garage floor, but filled there's a little bit of bow to long sides of tank. That normal? Not as bad as when i had a 55 brace break but still noticeable if looking top down

It's euro braces all around with a center brace incorporated. Wonder if i could add a lap band of sorts to make sure lol.

I would try and raise the tank so that it can be completely supported. Then drill hole in platform and use two 45s to get you where you need to be. Hope that makes sense

With a conventional stand perhaps, was trying to save $ on sump stand with cinderblock. Dont think i can circular saw thru those. On rc someone said widen the blocks but i figure that leaves a stretch down the middle unsupported. Maybe if i did it just on the end....

Just make a V shape with the cinder blocks at the end to accommodate the bulkhead and plumbing.

So something I was going to do with my mixing tank, which is a 250 cube in acrylic, was to overhang the tank above my sump like you are doing. To do this though, I had the main supports much like yours, but I made the top platform extend a bit out with 2x4s, and some steel brackets, that would support the corners on each side of the overflow without blocking the bulkheads or overflow part of tank.
Although, I switched the sump design so I will not be using that setup now and handling it with an extra pump and some plumbing instead

Any thoughts about the slight bowing, I assume it's normal? Just so I'm not paranoid about the even support, wondering if I couldnt find someone to trade a 125 or some other wider shallow footprint tank. (Bigger than a 40b, though in the end that might be good too.)

This tank setup ideally could serve as a QT or time out tank, but once up and running i was invisioning just a brightly lit macro algae tank with my hatching baskets of cuttlefish up high. (And adults at bottom of tank)

I personally wouldn't leave the acrylic tank overhanging like that. Acrylic really needs to be supported across the bottom especially thinner acrylic which your tank would seem to be made from allowing it to bow. I personally would just spend the money to build a cheap stand from 2x4's and a half sheet of plywood or osb, the whole thing could be done for less than $30 and would be much safer. On a side note you can cut or drill through cinder blocks with masonry blades/bits.

 

[Fitz19d]

Cheap was an excuse, the truth is I am not handy at all, probably lack half the tools etc.

I have a niceish wood stand from a 4x2 reptile tank, I could cut the short side down make it 18inch to match, but then I dont think that supports right since it's 4, 4x4 posts with the 4x2 framing that goes around the outside at top and bottom. There's nothing in the center. So all the support is the 4x4, but for the acrylic even with a couple sheets of plywood on top, isn't that considered not even because there isn't solid supports in the center or otherwise through ought the top surface?

I'll help you. If you want. Bring the material and dimensions and I'll help you build whatever you want.

Ask and you may find out, don't ask and you will never know.

 

[Fitz19d]

Actually, before I worry about the stand, I need to decide if the tank itself is even safe. The edges have the following bubbling/hazing along the seams, paired with the slight bowing unsure if normal for a cheap used acrylic or is this it starting to fail?

 

[Sctip]

OK let me know. I would chime in about the integrity of the tank but I don't know anything about acrylic tanks. Offer stands if you want to build a stand and we are close to each other.

Ask and you may find out, don't ask and you will never know.

The seam where it is solid white in the first pic has started to fail and needs to be repaired. It's not overly hard to do you just need the right tools and equipment. As for the crazing in the seams this isn't a sign of failure rather one of age and poor manufacturing processes but it wouldn't concern me. I have a shop and am willing to help you build and/or modify a stand as well, I'm in Westminster if that helps. The bowing stems again from poor manufacturing. The manufacturer built the tank with acrylic to thin for its height and length to save on costs. It will hold water just fine but it will bow much more than if it had been built using the correct thickness acrylic. hth
