Isn't there some sort of PH down that's used in Hydro? It should say on the bottle? Sorry, it's not my expertise. In AP, I'd say just use hydrochloric acid, and do it slowly. Mr Damage would be the local expert with Hydro. |

The amount depends what pH lowering solution you have and the carbonate hardness of your water. If it's simply running as a hydroponic system then then you should aim for a pH of about 6.0-6.3 and use Phosphoric acid (most common pH Down solution sold at hydro stores). Dosage will be trial and error. Fill a large glass with water, add a given amount of the Phosphoric acid (I'd start with 1ml per 50L) mix it into the large glass of water, then add that into the 150L |
