8.3.4. Feeding your Artemia salina
Feed your brine shrimps often to keep them alive. The best food is dry powdered
yeast (23a). Give them some every other day. Be careful not to overfeed them, as
doing so can cause the water to stagnate and poison the brine shrimps. If the water
does begin to stagnate (you'll see it darkening), transfer the brine shrimps to the
fresh saline solution you have prepared earlier (see 8.3.2).
Care and maintenance
Before cleaning, separate the device from the power supply by removing the plug.
Only use a dry cloth to clean the exterior of the device.
NOTE:
Do not use any cleaning fl uid to avoid damaging the electronics.
Clean the lenses eyepieces and lenses only with a soft, lint-free cloth, like a mi-
crofi bre cloth.
NOTE:
Do not apply excess pressure to the cloth so as to avoid scrat-
ching the lenses.
To remove more stubborn dirt, moisten the cleaning cloth with an eyeglass-clean-
ing solution and wipe the lenses gently. Protect the device from dust and moisture.
After use, particularly in high humidity, let the device acclimatize for a short period
of time, so that the residual moisture can dissipate before storing.
