    RTV108, pure silicone, or the silicone with *NO* mold/mildew resistant additives, i.e. GE1 if that's all that's available.

    I stick with marineland aquarium silicone. No questions about whether or not its the right stuff. Says so right on the container.

    Go to Menards, back by the paint dept there is Loctite Clear Silicone Waterproof Sealant--Aquarium Safe, it's a 2.7oz tube, runs about $3.50 a tube.
    I've used this for years, All Glass or Marineland silicone is not cheap!
    Good luck, hope this helps!

    You really shouldn't have to use silicone on your bulkheads, just make sure the rubber gasket is on the wet side.

    The reason all glass and marineland silicone is so expensive is because it cost money to relable other companies like GEs products

    I understand you get what you pay for but when it comes to just putting baffles in im not real worried about having the best quality. If i was building a tank i would prolly pay for the better stuff.

    Not really getting what you pay for, because like stated it is just the label. As long as you are sure that the silicone you are buying is aquarium safe it will be fine. But for me it was taking the guess work out of buying the correct stuff that will not kill my tank. There is a lot of threads with mixed answers about what silicone is and isn't safe. I was sick of the confusion so I went with the marineland.

    I used the black RV silicon found in the Rv department from walmart to silicon the overflow to the wall in my 350.
    6 months later and I have 26 species of SPS thriving in the tank now, so I would say it's safe.

    This is an age-old debate. People have had problems with various type of silicone. Mostly it is attributed to using silicone with mold inhibitors, but occasionally not. The key here is cure time. You really need to let silicone cure for 2 full weeks before putting water in the tank. 72 hours to fill test only.

    As for the product, all the pros use RTV 108 and you can get that at Grainger in DSM for less than $10 and I guarantee you that is reef safe. You can also get black which is I believe RTV103 from Grainger. Save yourself the question and get RTV and let it fully cure. you hear a lot of 'this worked for me' but stick with what everyone agrees on. RTV and 2 weeks.
