How
to grow phytoplankton.
Its cheap and easy and requires only a few minutes. There's other ways
to do it, this is just mine.
|
I use a plastic soda bottle,
a short length of airline, a couple of 4mm black plastic threaded adaptors, a
plastic jar, and A & B part nutrient and pipettes. |
Lit with a 15 watt 5000K energy saver lamp on a
12 hour photoperiod. Harvest every 7 days, keeping aside 10% to start a
new culture. |
1. A 1 litre system, but it can be easily scaled up . |
2. Drill a 4mm hole in the soda bottle cap. |
3. Drill a 4mm hole in the bottom side of the soda bottle. |
4. Get some 4mm threaded adaptors from Bunnings. |
5. Screw the 4mm threaded adaptors to cap and soda bottle. |
6. Add 100ml of greenwater starter, in this case Tetraselmis sp. |
7. Top up with R.O water and salt mixed to 1.014 specific gravity. |
8. Add 1 ml of nutrient part A. |
9. Add 1 ml of nutrient part B. |
10. Cut a hole in the side of the plastic jar. Invert the soda bottle
on top of the jar. |
11. Attach the
airline to the pump using a regulator to contol the air flow. |
12. Label with the species of greenwater and date. Light with a
daylight coloured lamp. |

How
to grow zooplankton.
Again Its cheap and easy, there's other ways to do it this is just
mine. |
In this case it's a rotifer culture, but artemia
works as well.
|
Providing a regular food source, live phytoplankton daily,
the rotifer culture can be maintained for many months.
|
1.Start with a white 20L bucket, white reflects light. |
2. Fill with R.O water and salt, then mix and aerate with a coarse
bubble. |
3. Check that you've mixed to a specific gravity of 1.014. |
4. Add a 5000K energy saver lamp on a 12 hour photoperiod.
|
5. Label the culture with a date and add a litre of greenwater. |
6. Add the rotifer starter culture. Feed live phytoplankton daily. Then harvest the rotifers on demand.
