silicone

Hello guys I have noticed while cleaning my tank that there's algea on silicone it self and some under but it easily brushes off with toothbrush I was wondering when do I need to be concerned about silicone since even now some bristles can go ab bit under the silicone?

Recently picked up a large ~200ish gallon Waterbox Peninsula for cheap, came into it knowing it needed a full reseal. Has a small bubble in the upper front corner seam; both interior and exterior faces of the seam are intact, bubble is approximately 0.2"×3" (half above waterline, half below)...

Hi all, I have a saltwater aquarium that I am using for research purposes. I need to secure some components within my tanks, but also have the ability to move them a few times a week so I don't want to use zipties as I would end up going through a ton of zipties. I found these silicone "zipties"...

Hey all. I just got a 75 gallon and notice a strange line on the top left of it. It runs a little bit and is wavy, and kind of thins out to nothing. I can feel it with my fingers it feels like a smooth bump. I just don’t know if it’s a crack or silicone. I am halfway setting it up and noticed...

I'm building a large 125 gallon acryllic tank into a sump and was wondering if anyone has done this and can post some pictures of a large acryllic sump DIY build? I really do not want to acryllic weld/bond the baffles to the sides of the acryllic sump so I have some future flexibility. Will...

So much talk of Red Sea tanks leaking on a weekly basis on forums, Facebook groups, Instagram, TikTok, YouTube, etc.... so I thought I'd collect some data out of curiosity. I will share the results with sensitive info removed on 12/31/2024. If you unfortunately had a Red Sea tank leak on you...

Hello all, need some advice for my Red Sea 300XL aquarium Looks like I have air in my silicone or bubbles. Should I reseal it or is it okey? I did a 100% water leakage test for 4 days with no problem. I e-mailed Red Sea and waiting for an answer.

Previous Owner had Styrofoam and Expanding Foam as a backing and bottom. How can I remove silicone residue?

Hi, I am comparing the Nuvo 40 long and the 50 lagoon and cannot decide. I read one bad review regarding the Nuvo 50’s build quality and was wondering if this is something to be concerned about? I’m mostly worried about the quality of the seams and water leaks, not so much the pump failing. I...

Last night I was doing some sump renovations, when I finished I realized the silicone I've used had a small label that read "anti-fungal" (I'm from Argentina and it's in spanish actually but I'm translating). I bought the same brand I always use, but this time my usual shop was closed so I went...

Hi, Looking at buying one of the Red Sea G2 tanks shortly. 625 is a perfect fit in terms of size and water volume for what I’m looking for however.. Any reviews on how the build quality is? Is there a noticeable improvement in the silicone? It’s the tank I’m leaning towards but I have that...

Hi, My tank is 15 months old and started leaking last week. The aquarium builder is building another tank as we speak but he originally used black silicone. The bottom front glass is leaking and has a 3 inch flat glass with silicone over it. I took pictures of the black silicone with what...

The inside rim of my tank's top frame has long been damaged--it's not the part holding the sides together, but the little ledge that extends out into the tank. Hadn't been a big deal, but for various reasons I want to change to a lid that would sit on that inside rim. I've tried to look for a...

Should I reseal 300 g 8’ glass cages tank? It does not leak, although has flat nonsticky silicone on one corner and a chip in another corner. If so what type of silicone is ideal and can it just go over old silicone as long as it still touches glass? What about placing new pieces of glass on...

I was drilling my Red Sea Reefer 250's ATO reservoir to convert it into a refugium. Well, drilling didn't go to plan and I cracked the tank (see pictures). I'm wondering if I can seal the crack with silicone. My thought is the reservoir is only 2 gallons, so there's not a lot of pressure from...

Hi All, I’m planning on buying a second hand (v1) reefer 350. Overall the tank looks good, I don’t see any issues with the seams, but I was wondering if it might be worth it to ‘reinforce’ the existing seams with an additional silicone seam? Mainly because the tank will be empty anyway, so I...

Hi, i want to add new black silicon sealant on every outside corner of my tank, is it have any effect if the black silicone sealant make contact with some my cured clear silicon sealant?

Hello everyone, I have recently set up a 75 gallon aquarium and one of the silicone seals appears to have algae growing underneath it in a few spots. The tank has only been set up for three months and was never previously set up so it is almost brand new. I do not want to name the brand in...

Hi all, I purchased a used 90g setup recently and wanted to get some opinions on the seams. Before I broke it down I looked and didn’t see any bubbles but I did notice the cuts I guess from scraping during cleaning throughout the years. The inner seals (between the glass) seem perfect. Should...

I noticed a gap in the silicone on the outside seam of a new 90 gallon aquarium. It is about a cm long and not very deep but is concerning to me. Is something to be worried about especially long term? The inside seam looks good, the tank is new and has not been filled.
