My advice for beginners
Find a good local fish shop
and build a relationship with the staff who will share their experience and knowledge with you as well as give you a ‘heads up’ as to when the best stock arrives.
Write an aquarium log
to keep notes of things such as dates you added livestock, test results, changes to lighting, flow and water parameters. This information will be invaluable should you run in to any problems.
Invest in an RO filter
and mix your own saltwater; not only will this save you time and money in the long run but you can be sure that your water always has the optimum parameters for your system.
Make any changes slowly
and only one thing at a time; if you make multiple changes at the same time you won’t know what helped or caused issues.
Do your product research and buy the best equipment you can afford from the start. These generally last longer, saving you the expense of having to replace or upgrade items at a later date.
Buy your own RO filter so that you can prepare saltwater at home, saving those weekend trips to the nearest marine store. (This also saves money as prevents impulse store purchases!)
Things I wish I’d known.
The importance of a good quarantine set-up. If I’d used one in my early days it would have saved me lots of heartache. These days I quarantine everything wet for a minimum of 12 weeks before it’s added to my display tank.
