The first thing you might be wondering is, "should I acclimate my macroalgae?" Absolutely, you should! It's true, macroalgae don't experience all the same types of stress that fish or invertebrates do during shipping. However, they can and do get stressed. And, that stress can be sufficiently harmful as to cause portions of the algal mass to die. Particularly in a newly established patch, a few dead, rotting pieces can adversely affect neighboring pieces of algae (bad apple effect!). Therefore, it's important to ease the algae into its new growing space.
Big stressors for macroalgae are:
- light shock.
All of these can be avoided by doing the following:
- When your algae first arrives, simply make a couple small openings in the package and allow the seaweed to breathe a little. This will allow for slow, gentle gas exchange. As carbon dioxide levels drop back closer to normal, the pH value will gradually increase.
- Warm/cool the package as necessary to match aquarium temperature. After approximately 15 minutes, it will be alright to fully open the bag and pour the contents out through a net. The waste water is discarded. As an option, one might perform a quick rinse (again through the net) using aquarium system water. This water too is discarded. The macro can then be tossed directly into the tank!
- Do leave the lights off for the remainder of the first day. This lessens metabolic pressure on the plants while they adjust to their new environment. If possible, it can be advantageous to dim the lights on their first day of operation over the new plant mass.
Because all selections in the CleanMacro™ Series have already been inspected/pretreated to remove potential pest organisms, you can spend more time with your fish!
