FAQs: Your 2025 Questions on Aquarium Supplies Answered
Is AquaStik Epoxy safe for reef tanks?
When used as directed and fully cured, AquaStik is designed to be reef-safe. Apply in modest amounts, allow it to set undisturbed, and monitor your skimmer and parameters afterward as a precaution.
How long does AquaStik take to cure underwater?
Initial set can occur within minutes, but full cure depends on thickness, temperature, and flow. For best results, avoid stressing the joint for several hours and plan scaping sessions accordingly.
Why do my suction cups keep falling off?
Most failures stem from biofilm, algae, or textured surfaces. Clean the glass thoroughly, lightly moisten the cup before application, and replace aging cups that have hardened. Avoid placing cups over seams or silicone lines.
Can I use Marina Suction Cups for heater cables?
Yes, they are suitable for routing heater cords, airline tubing, and small-diameter probe wires. For heavy cords or high-tension areas, use multiple cups for better security.
Are IRIS USA Clip Boxes waterproof?
They are moisture-resistant but not fully waterproof. Avoid storing liquids loosely inside. For added protection of sensitive items, keep them in sealed pouches before placing them in the Clip Box.
What sizes of Clip Boxes work best for aquarium supplies?
Small boxes are ideal for test kits and spare O-rings; medium boxes fit foods, dosing accessories, and nets; larger boxes handle bulky pumps or lighting accessories. Stack boxes by category to speed up maintenance.
Is epoxy better than super glue gel for corals?
They serve different purposes. Super glue gel bonds quickly but can be brittle; epoxy fills gaps and provides structural support. Many aquarists use a hybrid method: gel for initial tack and epoxy for long-term stability.
How often should I replace suction cups?
Inspect monthly and replace when they lose flexibility, become cloudy, or fail to hold after thorough cleaning. Environmental factors like heat and UV exposure can shorten their lifespan.
Will using epoxy affect my water parameters?
Properly used, reputable aquarium epoxies are designed to be safe. In small systems, large applications can temporarily affect skimmer performance or cause minor cloudiness. Consider staged applications and routine monitoring.
What’s the best way to prevent losing small parts?
Dedicate an IRIS USA Clip Box to “Spare Parts,” add mini organizers or zip bags inside, and label clearly. Keep it within reach in your stand or maintenance cabinet for quick access during water changes.
