Where To Start with Aquariums and More
Talking of phytoplankton, these are basically microscopic plant-like organisms which are photosynthetic creatures that drift about in the ocean absorbing the sunlight and turning it into delicious sugars. They are essential for your saltwater tank for the fact that the filter feeding invertebrates such as the sponges, clams and corals will feed on them for their nutrition needs. Phytoplankton have been billed a good source of nutrition for your marine life looking at the fact that they have a generally high level of concentration in Omega 3 unsaturated fatty acids which happens to be one of the key nutritional needs in a number of the invertebrates.
You will basically have three most common strains of the phytoplankton that you will be able to culture at home for your saltwater tanks. By and large, these are the strains such as the Nannochloropsis, Isochrysis and the Tetraselmis. And by and large, looking at all the available strains and kinds of phytoplankton that you can grown in your home for your saltwater aquarium, the one that actually stands out is Nannochloropsis. This is the particular phytoplankton strain that is largely seen to be the best for the fact that it happens to be well balanced, having such better levels of concentration of the essential fatty acids, HUFAs and EPA, which are more than essential for the growth of the fishes at their larval stage of development. For this reason if at all you are considering the breeding of saltwater fishes in your aquarium, then this is the best strain that you will be advised to start with. Over and above this, Nannochloropsis has as well been deemed to be a good fit for saltwater aquariums for the fact that it has some antibacterial properties.
You can choose to culture or not to culture your own phytoplankton anyway. The reality however is that growing your own phytoplankton will be a bit of an investment in time and energy as it takes some time for you to set up your culture station and to have them grow. Besides this in as much as the strains will be as hardy to grow afterwards, there will be a need for you to spare some time monitoring and for maintenance of the culture set up on a daily basis. Instead of going through all the stress there comes with culturing your own strains of phytoplankton for your need to dose your saltwater aquarium, you can alternatively settle for the many available commercial products for the same purpose and avoid all the inconveniences there may be with the option of culturing your own.
Note the fact that many aquarists do dose phytoplankton into their aquariums as a supplement to the feeding schedule given the fact that they happen to be so natural and nutritious food sources for marine life.
