Silicone baffles?

I have a diy tank and stand, and sump. I siliconed all the baffles into the tank and test filled the system. After 3 days the silicone on the baffles broke, and they fell over with the weight of the water. I had used tech 7 aquarium safe silicone. If I sand the glass slightly where the baffles are going in the tank with that help? Or has anyone else got any tips? Thanks

Can understand why tec 7 didn't hold for you , use a lot of this in the motor trade my only sudjestion is that there was some sort of grease ,soap or something like that on the parts .certainly I would slightly roughen the suffice will give a bit more bite ,ensure all parts are to totally clean and let cure for at least 24 hours .hope this helps ,and good luck

Thanks Robert, tanks was completely dry and clean when it was done and baffles were placed months before I added water. I'll just have to try roughing the glass up a bit and see if that holds.

There was another guy who built a tank using Tec 7 and time after time the tank leaked ....he eventually rebuilt the tank using silicon and hasn't leaked since...

Why not just use silicon?

There are different types of tec 7 some set solid and some don't
I'd guess that the one you used didn't

I'd suggest that you go to a lfs and buy specific tank build quality silicone

Just my suggestion tho

idea is the best , after all why use a product that's not really designed or the job when their are products available specificly for the job . While tec 7 is good it always seems slightly flexible when set

Thanks guys that's what I ended up doing, I got some at seahorse, and redid it today and got some spare that can be used under water if I need to do any repair work.

I built a 5ft sump a few years ago and purposefully did not use tech7 as it's flexible. I used aquarium silicone from seahorse, it's more expensive but never fails. I also cleaned the glass with nail varnish remover, got a large bottle of it in a local woman's hair and nail salon.

Once again

Make - Product name

Bond It - HA6 marine silicone
Soudal - Silirub AQ
Everbuild - Aqua Mate

I made quite a few tanks with those products(purposely designed for aquarium construction!)
Also way cheaper than what JBL is trying to push in small tubes in pet shops
Silicone has to be within best before date, shelf life is only 12m
Glass has to be completely grease free
