View Full Version : Oceanic Biocube 29, backwall return area issue

08/29/2017, 02:14 PM
Hi all,

I just got a 29 Biocube used and after cleaning it, I realized that the return chamber in the back, has a leak on a section of the silicone. This means that that chamber, will want to level with the display section up front.

I have it cleaned up and I am looking for advise on resealing it. My questions are:

Should I remove all the silicone on the back and redo it?
What Lowes or HD silicone should I get?
Do you have a link to any videos that can show me how to go about this?
What tools do I need? Can I scrape the silicone with a blade or should I use something else?

Any help would be greatly appreciated.

Pull the chamber off. Clean all the silicone off and any silicone 1 will work. Aslong as its silicone without any additives.

King of DIY in youtube has some tutorials that will be worth watching

Welcome to the biocube 29 club. Join us in the nano section once you're up and running. I'm interested to hear how your project comes out.

As mentioned, from what I've gathered here in the DIY forum, is that you'd want to scrape all of the silicone out (though I'd be careful around the bottom frame silicone joints) with a razor blade. Once scraped, clean it out with rubbing alcohol, and then you can re-seal it.

You can use GE silicone I if you want to go the traditional route. I believe that the stock install uses black silicone though. I'd recommend a quick search of the DIY forum for black RTV silicone recommendations.

Hope that helps, look forward to seeing you around in the nano forum!

Thank you guys. I'm going to attempt this over the weekend and see how it goes. I'll report back once I'm done.
