Aquarium Supplies in Perth
Gallery Aquatica is a reef and freshwater aquarium store in Tingalpa, Brisbane, and we ship aquarium gear to Perth. We have no shop in Western Australia, but all of the dry goods post over, and Perth's water is the one profile in the country where the treatment gear is not optional for most tanks.
What Perth tap water means for your tank
Perth has the hardest and highest-mineral mains water of any Australian capital. The supply is a blend of dam water, groundwater from the Gnangara and Jandakot aquifers, and a large and growing share of desalinated seawater, close to half the total. The groundwater component is the issue: hardness in those zones can run from 200 to 300 milligrams per litre, and total dissolved solids across the city are the highest of any capital, reaching into the high hundreds. It also varies a lot by suburb and by season depending on which source is feeding your area.
For an aquarium that means the tap is carrying a heavy, shifting mineral load before you have added anything. Hard-water species like African cichlids will actually take to it, but a reef tank, a planted tank or any soft-water fish needs that load stripped out first. On water this hard an RO/DI unit is not a nice-to-have, it is the baseline, and because the incoming TDS is so high your carbon and DI resin work harder and need replacing more often than they would anywhere else in the country. Buying resin and cartridges ahead is sensible here.
The gear that suits Perth water
- An RO/DI setup as the foundation for reef, planted and soft-water tanks. This is the single most useful thing on hard Perth water.
- Spare carbon and DI resin, because high incoming TDS exhausts them faster here than elsewhere.
- A TDS meter and test kits to track your own suburb's numbers and know when resin is spent.
- Supplements and buffers to rebuild water to a controlled target after purifying, or to hold reef alkalinity.
Shipping to Perth
Dry goods ship to Perth with Australia Post or Aramex, so all of the water gear above reaches you normally. Livestock is more restricted by law: live algae and snails cannot be sent to Western Australia at all, and fish ship Airport to Airport by custom arrangement, with remote WA postcodes quoted individually. We usually dispatch within seven business days of full payment, and once a parcel is with the courier the delivery time is theirs, so we do not promise a day. The full rules are on our freighting and packing page, and everywhere we deliver is on the Australia-wide shipping page.
Common questions
Do you deliver aquarium supplies to Perth?
Yes. All dry goods, including RO/DI gear, ship to Perth via Australia Post or Aramex. Live algae and snails cannot be sent to Western Australia by law, and fish ship Airport to Airport by arrangement.
Is Perth tap water hard?
Yes, the hardest of any Australian capital. Groundwater zones can run 200 to 300 mg/L hardness and Perth has the highest TDS of any capital city supply, though it varies by suburb and season.
Do I need an RO/DI unit in Perth?
For a reef, planted or soft-water tank, effectively yes. On water this hard it is the reliable way to a clean baseline. Expect your carbon and DI resin to need replacing more often than in softer cities, so keep spares on hand.
How long does delivery to Perth take?
Orders are usually dispatched within seven business days of full payment, then Australia Post or Aramex handle delivery. We do not promise a delivery day, your tracking shows the carrier's estimate.
