If you possess a copious Biorb marine tank, you can save a lot of cash by sourcing your salt cheaper than the official Reef One salt. You do need to think which salt brand you are going to take advantage of. I would say that salts for marine aquariums are either 'marine' salts or 'pro/reef' salt.
The 'pro' and 'reefer' salts have better levels of elements (i.e. Ca, Mg). You really only need these if you are keeping corals in your fish tank. If you hold corals, you will notice that Magnesium, Calcium and Sodium Bicarbonate are used day by day by your animals.
Salts I have labelled as 'marine' salts commonlycontain basic levels of elements. This is not a glitch at all if you are only keeping fish.
You need to contemplate about the form of filtration system you are running too. Certain people use something called ULNS. This means "Ultra Low Nutrient System". If you are using one of these systems, then it is critical that the alkalinity of your salt is not about 8. This is very significant. There are specialist salts that are advertised as being ULNS appropriate. It is worth taking a look on the salt manufacturer's website as the chemical levels will be to be had for you to verify.
Personally, I have tested a salt called Tropic Marin Pro. This has an alkalinity level of 8dKH. By the way, dKH is the German measurement of degrees of hardness of water.
As a marine Biorb fish tank possessor, you are likely to keep fish and not corals. To be reasonable, I believe you would struggle to keep all but the most basic of corals in a Biorb system. Accordingly, it makes common sense to look for a basic 'marine' salt. Brands that I have used in the past include Seachem, Kent, Instant Ocean. If you type one of these brand names into Google search, you will be able to find the cheapest location to acquire these from.
You may ask yourself how habitually you will consume the salt? Well, in a 60 litre tank, you should be replacing 10% of the water every two weeks. You can see how your salt usage over a year will add up. A little expenditure of currency now for salt, will save you a lot in the long run.
Biorb Marine tanks are a smashing way to own a small chunk of a real Reef in your room.
