Plugging holes

    Strictly talking about a reef tank here, I took off the old overflows and have 4 holes in the bottom of the tank. Originally I was going to put in bulkheads and plug those but I'll never use them again (I'm drilling holes farther up the back for a different overflow system). I'm thinking of just siliconing glass over the top as I did on a past tank.[​IMG]

    Sorry I'm not sure why Tapatalk is duplicating posts for me.

    Siliconing glass pieces over the top of these holes should work fine. I have done it a few times in the past.

    I didn't think about that... I'd always used a bulkhead and plug. I have a drilled 40g that I'm going to plug this way. Thanks for the idea!

    Sounds reasonable to me. However, bulkheads might be less expensive? I don't know.

    Glass would definitely be an option. Just make sure it can stand the weight and pressure

    If that tank is glass get some glass covers made and silicone it on. Acrylic will not silicone strongly to glass and vice versa. You could also put inside thread bulkheads in and screw a plug in and seal those that way also.

    Siliconing 1/4" glass I had from baffles in a 20L I no longer have.
