Attaching Heatsinks to Hoods

[lpsreefer]

High heat job weld would work. I would suggest though if u can get four holes drilled into your heat sink to mount in to ur hood. That would do best.
I had a similar problem with my 29 biocube.
A 2 dollar drill bit with screws. its a lot easier to change then a permanent thing.
Just my two cents.
As I took my led out and fitted it to a different tank.
