What is the Seahawk Hydro Tank used for?
Seahawk Hydro Tank is a collapsible reservoir for hydroponic nutrient solution, rainwater collection, irrigation systems, garden watering, and general water storage. It works with recirculating systems, gravity-fed drip setups, and pump-fed automation.
Is the Seahawk Hydro Tank rigid or collapsible?
It’s a flexible, soft-sided tank made from heavy-duty PVC. It folds flat for storage and is UV- and mould-resistant. It’s also commonly listed as BPA-free and non-toxic, making it safe for hydro, garden, and indoor use.
What sizes and dimensions does the Seahawk Hydro Tank come in?
Sizes include 100L, 200L, 250L, 380L, 500L, 750L, and 1000L. Dimensions range from 40cm to 120cm in diameter and 70–98cm in height. Check the product page for exact measurements by size.
How do I choose the right Seahawk Hydro Tank size?
Choose based on your system volume, refill frequency, and space. Smaller sizes suit tents and tight spots; larger ones offer more stability and fewer refills. Bigger isn’t always better — balance size with space, weight, and maintenance preferences.
Is the Seahawk Hydro Tank easy to set up?
Yes — most setups take just a few minutes. No special tools are required. Set the base, insert the frame, fit the liner, and you’re good to go. When not in use, the tank folds down flat for compact storage.
Where should I place the Seahawk Hydro Tank?
Use a flat, level surface with no sharp edges. On concrete, use a protective mat or tarp. Indoors, place a tray under it on wood or carpet. Keep hoses tidy and avoid placing it where it might be bumped or dragged.
How heavy is the Seahawk Hydro Tank when full?
Water weighs about 1kg per litre. A 500L tank weighs ~500kg when full. Always check that your surface can support the weight. Never try to move a full tank — drain it first to avoid damage.
Does the Seahawk Hydro Tank come with a tap or outlet?
Most models include a built-in outlet or tap. Outlet size may vary by batch, so check your specific tank before buying fittings. You can also connect a submersible pump inside or plumb from the outlet.
Can I use a pump or air stones in the Seahawk Hydro Tank?
Yes — it's designed to work with submersible pumps and air stones for nutrient circulation or oxygenation. Mixing nutrients directly in the tank is common. Just protect the pump intake from sediment buildup.
Do I need filtration or a lid with the Seahawk Hydro Tank?
Filtration is strongly recommended, especially if you're using drippers or running nutrients. Most tanks include a lid or cover. Keep it closed to prevent algae, evaporation, and contamination from dust or bugs.
Is the Seahawk Hydro Tank leak-proof?
When properly assembled on a smooth surface, it should be watertight. Leaks usually come from loose fittings, twisted gaskets, or sharp surfaces underneath. Don’t drill extra holes — use external plumbing instead.
How do I clean the Seahawk Hydro Tank?
Drain and rinse thoroughly after each run. Use gentle cleaners — avoid harsh chemicals that could damage the PVC. Clean more often if you're running organics or see buildup, slime, or odour.
Can I store the Seahawk Hydro Tank during off-season?
Yes — clean and dry it completely before folding. Store it cool and out of direct sun. Avoid folding it sharply in freezing conditions, as cold can make PVC more brittle.
What’s the most common mistake with Seahawk Hydro Tanks?
Placing the tank on rough or sharp surfaces, which can cause abrasion leaks. Another big one: skipping filtration, which leads to clogged pumps and dirty reservoirs.
Can I use the Seahawk Hydro Tank for space-saving or gravity-fed systems?
Absolutely. Its flexible footprint and collapsible design make it great for small spaces. It works well with gravity-fed systems or auto top-ups, as long as components are installed securely and level.
