Magnesium is present in Natural Sea Water (NSW) in a fairly high concentration (1350-1500 mg/L). Magnesium is an essential part of chlorophyll, which is necessary for photosynthesis. Without photosynthesis algae, and hence the corals, which we have in our aquariums would not survive. Magnesium also has another important function in that it allows the correct combination of calcium and alkalinity (or carbonate hardness) to be maintained. Maintaining a correct magnesium concentration is therefore very important and is indirectly responsible for fast coral and calcareous algae growth. Magnesium is depleted by algae growth and also by the use of excessive kalkwasser or by going far beyond natural calcium, alkalinity and pH values. Salifert’s Liquid Magnesium is highly concentrated with each litre containing approx. 25000 mg of magnesium. To avoid an ionic imbalance, the magnesium in the supplement is balanced with ions such as sulfate, chloride, bromide, sodium and calcium.
Fish Orders
You can enter your required delivery day in the box provided at checkout so you can order in advance. Unfortunately, we cannot deliver livestock to Northern Ireland, or the Isle of Man.
Please note we cannot deliver the day after a bank holiday..
Our fish are placed in plastic bags with water and oxygen before being put in boxes. Tropical fish are then put in a suitable insulated box with a heat pack if necessary. This should ensure minimal heat fluctuations and keep the fish safe.
.
Due to the packing costs involved, we have a minimum order of £35 on livestock orders (excluding delivery).
.
They will then be shipped on our overnight service. You must be available to receive and sign for the fish to receive our arrive alive guarantees. Please then read our acclimatising guide on the best way to settle your new fish in. If there are any problems with your delivery please call us. There are sometimes delays out of our control due to weather, traffic and accidents, please call us if your delivery is late, we do still need you to be available for the delivery due to it being livestock. Remember to choose your fish carefully after reading our guides as we cannot take any returns on livestock.
