pH was very low again. Below 6.0. Added four teaspoons of lime to bring up the pH. Also added two teaspoons of kelp extract and one teaspoon of chelated iron.

Adjusting aquaponics pH with more hydrated lime

The pH stabilized from yesterday’s calcium dosing at 6.4.
Today, I decided to add another tablespoon to bring it up a bit more. Five hours after dosing, the system reached pH of 6.8.
Adjusting aquaponics pH with hydrated lime
Log date: 11/1/2014
The aquaponic water has dropped down to pH 6.0 again.
This is a chance to add some calcium to the system via hydrated lime. Added one tablespoon to the water.
A preliminary test shows pH 7.2. But need to let the water stabilize before the test is accurate.
This will add some needed calcium to the plants since the water here is very soft containing no calcium. Last week, the system was dosed with kelp extract and the plants have had minor responses.
