hi guyz

would anyone know the potential
of a chip on a tank, a pal of mine has
an old tank that he wants to setup
it 3ft with 4mm glass,he has a big chip
on it at the top of his tank on the
back panel, the chip is about
2cm across and bout 2.5cm deep
infact that whole piece is out,
not sure what he did to get that but
is there a way to like fix it?
it isnt seen if his canopy is put on as it is hidden but
if he had to fill it up with water would that cause the chip to
spread into a crack or could we like sand down all the rough edges
and smoothen it down, would this sanding prevent the crack from
happening, oh and also could we use some silicon on its smoothened edges
to prevent the crack ?

would this work out?

Hi Ocellaris, you can have the tank repaired, a back panel would be approx R100-R150 to replace!

thanx Mtroboer
i spoke to a guy that builds tanks he said that
even if i siliconed a piece of glass over that
it would be fine,but im still sceptical, i thought
he could just sand it down and apply silicon and it be fine
cos you dont even see it cos his canopy covers it...

Yip, siliconing a piece of glass over the spot would work 110%, I even did this with a cracked bottom on a 3ft tank which works fine till this day! You said the canopy covers it, so I would definitely go that route.:thumbup:

thanx Mtroboer

in like an overflow to a sump or would this be dangerous to do ?

That would certainly work, just make sure the edges are sanded down and coverd with some kind of cover to prevent injuries! You could build a overflow box at the back of the tank like this:

That way you could fill the overflow with crushed LR for extra filtration capacity as well as a refugium, just make sure to put in a standpipe to raise the waterlevel to the desired level! If you do this the DIY way you could get away quite cheap!:yeahdude:

hi Mtroboer you hit the nail on the head, i think this is an excellent idea we could use this to our advantage then :) thanx buddy, for sure i will sand off the edges, great idea with the crushed live rock... my pal will be quite happy, so i guess we have an over flow box to create :)

I guess it could work if the plastic is fairly thick (+/-4mm)... if you want to go that way just sand the edges of the plastic prior to siliconing to ensure a better bond, and TEST before filling it with saltwater!!

What kind of plastic do you want to use?

I would seriously punt using glass over plastic, while you cn happily use plastic, the bond from plastic to glasss will proove problematic IMO. any local DIY shop will be able to cut and sand down the glass to your specs ... easier overall

Do be sure to check if it is possible for a crack to run/get worse, if it is possible for the crack to run it will, you can drill through the glass right on the bottom of the crack as this will prevent it running - personally though, i'd replace the glass just for peace of mind.
