AQUA MEDIC PH COMPUTER SET

Microprocessor controlled pH monitor and controller The pH computer-Setutilises a modern microprocessor, which provides high precision measurement and control. ThepH computer-Setis used to control precise values of pH in the aquarium or the Calciumreactor.

KW Zone Dophin Wet/Dry Power Head

For stabilizing water parameters safely - prevents pH value variations

• For the gentle and safe increase of carbonate and total hardness

• Raises and stabilizes the pH value

• Reliably prevents dangerous pH value variations

Natural processes in ponds and heavy rainfalls influence the carbonate hardness and the pH value. This may lead to life-threatening pH value variations.

sera pond bio balance increases the carbonate hardness as well as the total hardness in a natural, gentle way and thus stabilizes the pH value for a long time. sera pond bio balance ensures a balanced mineral supply, stress reduction and optimal environmental conditions for fish and plants.

Water testing for experienced pond keepers

Experienced pond keepers check their pond water regularly. This allows taking measures, for instance against algae, quickly and easily, without the need to use chemicals.

The sera Koi aqua-test box contains the following test kits:

• pH value
• total hardness (GH)
• carbonate hardness (KH)
• ammonium/ammonia (NH4/NH3)
• nitrite (NO2)
• nitrate (NO3)
• phosphate (PO4)
• iron (Fe) and
• copper (Cu)

The new sera pond pumps SP are designed for small systems and fountains They allow efficiently pumping smaller amounts of water. The pumps can be attached by means of their holder plate equipped with suction cups.

AQUA MEDIC PH CONTROLLER WITHOUT SENSOR

The pH controlleris a precision instrument for controlling the pH value in aquaria. In combination with a CO2system and a solenoid valve the pH can be maintained at a constant level, and the CO2supply to aquatic plants can be controlled.

Powerful circulation pump for aquaria For use as circulation and return pump in salt- and freshwater aquaria. Rugged pump housing. Electronic directed energy saving motor with high effi ciency. Polished ceramic shaft and bearing guarantees silent operation and long term maintenance free operation. Submerged and non submerged set up is possible. Prefi lter basket and hose connections included.

The T computer-Set a precise multi-functional temperature controller and is complete with a digital temperature sensor. The mode of operation can be set using the function keys, either as a heater or cooler controller. In "heating" mode, the temperature is controlled to the set value using a proportional pulse system with an accuracy of 0.1C. In the "cooling" mode, the accuracy is 0.5C. The maximum operating power is 1,000 watts for heaters and 600 watts for coolers.
