My 315G Plywood Tank Build

im gonna try to measure the clearance, make the back wall framed with 2x6, hopefully that would be enough clearance to do internal plumbingBadOleRoss;3974632; said:
2x6s will work with the plumbing if you tighten up the fitting so there is not a lot of extra pipe between the bulkhead fitting and the down pipe. I just measure mine and it comes out 7"s but there is 2"s of extra PVC in there!xdragonxb0i;3974835; said:
so ross what went wrong on your tank?
will silicone stick to cured Pond coat? Im still not sure whats the best way to apply the glass and silcone with pond coat.
I wonder if we can just use pond coat, and bond it to the glass.

I just completed a test using PC, Wood, Glass, Acrylic, Silicone and my whirlpool tub. I took a piece of plywood, painted it with PC, stuck a piece of wood to it, a piece of acrylic to it, I stuck another piece of wood on top of the glass and acrylic and I put a beadof silicone on top of an area of the pond coat. I let the PC dry/cure for over 3 weeks. Yesterday afternoon I floated this mess in my whirpool tub to see if the PC stuck to these surfaces. The pondcoat did fine with acrylics but pealed right off the glass.xdragonxb0i;3976691; said:
Cured or not, PC does not stick to glass, not in my house anyway. I was also able to peal the siicone off PC with my fingers. It did remove 1 layer of PC with it but it came nowhere near pulling offwood as in Joey's test. My silicone was only on the PC for about 3-4 days. I cannot and will not count on PC bonding to glass to help me get a seal. What I am planning to do at this point in to coat my viewing window frame with fiberglass resin. Doing this will give the silicone something to bond to and it will give the PC something to bond to.BadOleRoss;3976889; said:I just completed a test using PC, Wood, Glass, Acrylic, Silicone and my whirlpool tub.

so Pond coat doesnt adhere well to glass or silicone. cured or not.
That's what I have determined but I am not finished yet. Like I said, I plan of taking a piece of emory cloth to the glass glass tomorrow to give me a rough surface to apply the PC too.
Do you know if anyone ever glued the glass first with silicone and let it cure then. Paint over it.
Maybe we should try putting pond coat with drywall mesh. The same way you sealed the corners of the plywood
