Marine Aquarium Set Up

Step-by-Step Guide

As well as stocking 100's of marine fish we sell everything you need to set-up and run a marine aquarium. We also have a team with Marine fish keeping expertise who are always happy to help and give advice!
Follow our simple 5 step guide with a basic outline on setting up a marine tank from scratch, with some helpful tips and information along the way. 

Step 1

Choose the right tank
A small tank may seem tempting to a beginner, but in actual fact it is better to choose the largest tank that your budget/space will allow. Smaller tanks often require more care and maintenance, and any water changes will take over your tank very rapidly and can get dirty a lot faster. If you're a more experienced fish keeper then try a nano tank.
Tanks will usually come with a filter and pump suitable for the size, so there's no need to worry about that. Other accessories can be added to your tank, so please ask us about added extras.

Step 2

Fill it with water
It's not quite as simple as it sounds...
Your marine tank will need to be filled with RO water (reverse osmosis) mixed with a good quality salt. Specific gravity (salt levels in tank) needs to be between 1.022 and 1.024 which can be measured using a good quality hydrometer.
(We mix our own RO water with the exact gravity if you are unsure)
Tank Positioning
It's important that your tank is positioned correctly so it's safe for your fish. Don't place a tank near any doors, windows or radiators!
Added Extras
Add coral sand/gravel at the bottom of the tank. This helps maintain pH levels and looks good too. If you want to add fish that like to burrow, then use sand rather than gravel but otherwise gravel is good and easier to clean.
Use live rock for added filtration. Add colony when adding fish to assist in friendly bacterial growth to break down the fish waste more efficiently.

Put your feet up
Your tank now needs to be left for 2 weeks to settle before thinking about introducing any livestock. Add the 'Clean Up Crew' first e.g. Turbo Snails and Hermit Crabs. These will scavenge for algae, and help keep the tank clean and healthy. Check which ones are safe to have with fish and corals.

Rinsing Gravel
It may be an idea to give your coral sand or gravel a rinse under a tap in a colander. It will get rid of excess dust putting less strain on the filtration system

Step 5

Start adding livestock
When you start adding livestock, speak to us about adding in a protein skimmer to help keep the tank healthy and cleaner.
