About Marine Phytoplankton: Live Marine Fish Food

by Sean Taj

Tridacna Clams love PhytoplanktonBuying marine phytoplankton, also known as microalgae, is one of the best decisions you can make for the organisms in your saltwater aquarium. Phytoplankton is microscopic organisms pet stores and online retailers sell as food for your fish, clams, and other underwater dwellers. Phytoplankton for fish offer up natural nutrients, allowing your fish to lead longer, healthier lives in your aquarium. You can buy phytoplankton for fish in most pet stores, but you may not always have time to run out that week. There are advantages to shopping in store, like the ability to look over your different options and consult with the helpful staff, but if you find yourself in a situation where you can’t get to the store, you can also order phytoplankton online. If you are on vacation, for example, you can schedule phytoplankton deliveries online easily from a remote location. It doesn’t beat the in-person experience, but it’s a convenience when you need one.

[Phyto]

Getting phytoplankton for fish, clams, or shrimp in your aquarium will also be better for them than less-than-fresh fish food for a number of reasons. First one being that phytoplankton is the freshest option. The organisms can be used in addition to the food you have in your regular feeding routine. Saltwater aquarium phytoplankton also create an authentic sea environment for the organisms in your tank.

How to Add Phytoplankton Into Your Tank

Even Sea Cucumbers and Nudibranch love Phytoplankton

By following a few easy instructions, you can get a live blend of phytoplankton delivery that greatly benefits your tank. Live, wholesome bacterioplankton (e.g. PNS Probio™) enhance these benefits. Phytoplankton deliveries come in squeeze bottles for precise dosing . After you add saltwater aquarium phytoplankton, you should turn off any skimmers, or UV lights for about 1 hour minimum so the phytoplankton can be consumed After that time, you can turn your equipment back on and watch your aquarium thrive.
