Phytoplankton

bygreg.chernoff

The first link in a food chain is always a primary producer, like phytoplankton (i.e.manbetx3.0最新algae, plants, various types of bacteria).This is because all other living things—consumers—are incapable of synthesizing organic substances from inorganic ones.Primary producers rely on inorganic sources of energy (sometimes chemical, but usually from light).Using this energy, they take substances such as ammonium andphosphateand convert it into biomass—biomass that may be consumed by herbivores and subsequently passed down the chain.Consumers generate metabolic wastes such as carbon dioxide and ammonium, which are readily taken up and recycled by the growing producers.

Phytoplanktonare basically tiny (generally unicellular), plant-like organisms.manbetx3.0最新Most of the phytoplankton are from a large group of distantly related primary producers referred to as the algae.Though they do not share similar lineages, they are strikingly similar in form and habit!all are miniscule, photosynthetic organisms that live suspended in the water column.It is believed that they carry out most the planet's primary production.Indeed, life on Earth wouldn't be even remotely the same without them.Andalmostas importantly?They can improve the health of a marine aquarium system.

The Green Machine

The world's oceans are crisscrossed by steady surface water currents.When they collide into landforms or into each other, some are driven to the depths.This action pushes deep waters up to the surface in a process called upwelling.These waters from the deep are laden with nutrients.Why?Because when anything dies in the water column, it sinks to the sea bottom.There, nutrients accumulate, since mixing between different ocean water layers is minimal.Minimal, except, in areas of strong upwelling!This critical ecological process is known as the biological pump.

Other than dissolved nutrients, there is a lot of something else in the shallows of an upwelling zone: light!This means that photosynthetic plankton may thrive there.These areas sometimes produce vast pastures of phytoplankton that may be observed from space.manbetx3.0最新Massive blooms produce a heady amount of microalgae that spread out into the rest of The Ocean.

That last part is critical—this is a major source of the phytoplankton on coral reefs which are notoriously nutrient-poor environments.Plankton simply washes in from the open ocean via the tides.Thoughphytoplankton speciesclaim only a modest portion of primary production on the reef itself, they are nevertheless important in that they serve as a major source of vital nutrients such asomega fatty acids.

Using Phytoplankton in ReefAquaria

Various products are available for home aquarists that wish to use phytoplankton.These might supplement the diets of disparate invertebrates including certain corals, clams,tube worms, sponges, and other such fine-particle filter-feeders.They also promote large populations of pods, which depend upon phytoplankton during certain (especially larval) life stages.

These may be live or preserved products.The idea with all of them is to add just a little at a time, but frequently, rather than adding a whole lot on rare occasions.Some aquarists even feed continuously by way of dosing equipment.It's just fine, though, to pour in a small amount once each evening.Think of it as replenishing with the tidal cycle.You only need to use enough to impart a barely discernible greenish or yellowish tint to the water (this will go away very quickly as the phytoplankton is consumed).

What Makes a Good Phytoplankton-based Aquarium Feed?

There are a handful of "phyto" aquarium foods in the marketplace.They can vary quite significantly from one another in many respects.The best phyto product has the following attributes:

  • It is a live (rather than dead and preserved) product.
  • It is nutritionally balanced.
  • It contains a wide range of cell sizes.
  • It is easy to use.

Live products are vastly superior for a number of reasons.First, a product made up of intact, living cells is a lot cleaner as a feed than those that are made of dead stuff.So, it's much harder to pollute your tank from overdosing when using live phyto.In fact, live and growing phyto actuallyremoveswaste products from the aquarium water!Also, it stays up in the water column where filter-feeders can get it, unlike some dead or artificial formulas that quickly settle out over the tank bottom.

Mixed-species phytoplankton products are preferable.Why?Because no single species of phyto is perfect.The right blend of species, however, can result in an ideal nutritional profile.It also provides a wider range of cell sizes!this is great because it makes sure that all different types of filter-feeders get their share.

Is phyto easy to use?It can be, and it should be.The best products come in a resealable container that is suited for multiple use.Some even come in a bottle with a dosing neck for easy measurement.Your dosing routine can bereallysimple by setting up asubscriptionfor regular, automatic shipments of live phyto by mail.As many successful reef aquarium hobbyists will attest, adding phytoplankton is well worth the small investment in effort and time!

    manbetx3.0最新The phytoplankton I have a crush on which I learned about from AlgaeBarn is OceanMagik.Thank you, Greg, for turning me onto this product that has made my tank diamond clear and kept my corals vibrant and absolutely gorgeous.manbetx3.0最新When setting up my RedSea 170 I struggled with excess slime and stringy brown algae.OceanMagik has helped make my tank a spectacular showpiece.Thanks Greg!!Get your OceanMagik and witness the transformation for yourself!

    So if my bottle of ocean magik is outdated by a few weeks but does not smell like sulfur or anything foul, can my tank still benefit?

    Phytoplankton is so important to our reef tank's and I don't think most people realize that.I try to spread the message.manbetx3.0最新Great job Algaebarn!

      I think it is better to dose you tank with phytoplankton after water changes, so that copepods and invertibrats can continue to feast on it.If like bacteria, you should start with small doses of phytoplankton until the population of pods increases during the first few weeks then increase dosing to the recommended phytoplankton doses for your tank size.

    This is pretty interesting and makes plenty of sense.I think I will try live once I'm out of my current supply.manbetx3.0最新Thanks Algae barn!

    Is it beneficial to start dosing phyto after the tank has cycled, but before adding corals to get a good population going in the tank?

      Hi Debra,

      Yes, we recommend adding phytoplankton and copepods to your tank after the cycle so that you can build up a huge population!

    Was originally going to buy pods from my local fish store, but they said nothing about the pytho.I started doing some searches and when I found this site I was happy about how much information they provided, and also the bundle packs that included what benefits eachother and your tank.Love this company

    You have the phyto so the next logical step is to work on rotifiers.Breeders and coral owners are both consumers and it would fit in well with your niche portfolio.
