Marine fish tank products for sale and home delivery. For all your Marine Fish needs including water treatments, aquariums, conversion kits, food, marine lighting, salt and coral care.
Marine fish are saltwater fish, usually found in the ocean. Their water needs to be kept at a higher temperature than normal "coldwater" fish, and their water must also be salted with sea salt.
Please select from the Marine Products below to buy at our best prices:
Lighting – Fish will be fine with normal lighting, but invertebrates, such as coral will need much brighter lighting, and the deeper your tank, the brighter the lighting will need to be.
Skimmer – A skimmer will remove excess protein and decaying waste/fine matter from the water.
Sand – A covering of 2 inches is best unless you are using a DSB (Deep Sand Bed) which can be up to 4 inches deep.
Salt – Aim for a gravity of 1.022 for a fish only system, 1.026 for invertebrates only or a balance of 1.024 for a mixed aquarium.
Hydrometer – A basic tool to measure the salt content of your water, they can be prone to misreading, so be sure to always wash the unit after use to prevent this.
Test Kits – All conditions are important in your aquarium, but some more so at different stages of having your tank. To start off pH and ammonia is the most important, then move on to include Nitrite (NO2) and Nitrate (NO3). If stony corals are present then calcium will need to be tested also, followed with Phosphate, kH and GH.
Live Rock – You can use live rock as your main filter system for your marine aquarium. If this is the case then we advise to use 1kg of live rock per 9 litres (2 gallons) of water. It’s important that there is a flow over all of the live rock to prevent ammonia pockets building up as these can cause problems.
Filter – If live rock is now the main filter system then an external filter is your best choice as they have a larger turn over and can cope with larger loads.
Wave Maker – These are used to direct the flow around the tank, to prevent ammonia pockets and keep the live rock alive, simulating the ocean’s natural flow.
