Review: Works as it should - Everbuild Everflex Aqua Mate is a reliable, fish-safe silicone sealant designed for aquarium construction and repairs. It forms a permanently flexible, watertight seal that can withstand continuous water immersion once fully cured. The translucent finish keeps the tank looking clean, and it adheres well to glass, providing a professional-quality result. Pros: Fish-safe formula, waterproof, permanently flexible, low dirt pickup, easy to apply. Cons: Needs 24 hours to fully cure, emits noticeable odor during application, cannot be applied underwater. Bottom line: A top choice for aquarium enthusiasts, offering durability, safety for aquatic life, and excellent sealing performance. Perfect for building or repairing tanks with confidence.
Review: Excellent aquarium sealant - I recently bought a second hand aquarium which had seen better days, on investigation the sealant had pretty much failed all across the back on the bottom of the tank, although the sides were still solid , so I removed the base and stripped off all of the silicone and used the Everbuild Aqua mate silicone to re-attach the bottom glass and reseal all of the edges. It worked brilliantly. It was very easy to use, had a reasonable time (about 10 mins) before it started going too hard. I left the tank for 48hrs to fully dry and filled the tank. The seals are great even where I've gone over the original sealant. Considering I've never repaired an aquarium before I wouldn't have any reservations doing the same again in future. In my opinion 10 out of 10
