Και γιατί αυτό;

Όταν έχεις σύστημα χωρίς controller είναι λογικό να βάλεις τη ροή του CO2 χαμηλότερα, ειδικά και αυτοί που δεν έχουν καν solenoid και δουλεύει 24ώρες η παροχή.

Με τον controller έχεις τη πολυτέλεια να αυξήσεις την ροή για να έχεις γρηγορότερα αποτελέσματα αφού θα την κλείνει αυτόματα σε περίπτωση που το pH πέσει κάτω από τις προγραμματισμένες τιμές.

Αυτά γρφει και ο Tom Barr

Remembers, the pH controlled system must have a higher setting to throttle back and forth between too little(CO2 on) and too much CO2(CO2 off setting).

therefore the amount of CO2 rate is always higher than a tank's demand, should anything go wrong, then it will error on adding too much.

Needle valves are safe unless you mess with it or something monkeys with the setting. Clippard valves have a another pre set disc to prevent that from occuring by preventing the valve to be turned further, other's have a lock out, some do not though.

You should check it every so often also.

If you do a large uprooting, pruning etc, reduced water surface moevement etc, anything that changes the CO2, then you can have a spike.

Any one of the systems can go terribly wrong.
Both Amano and myself have killed things with pH controllers also, I killed a marine system.

I've not killed any fish to date with CO2 in FW planted tanks using just the needle valves.
