This GH booster is designed to be used with the Dry Fert for Low Tech (Non-Co2 Aquarium) sold on this website only. The reason it is designed to work with our Dry Low Tech Fertiliser only is because generic GH boosters contain magnesium, where as this one does not because our fertiliser already contains the right amount of magnesium so there is no need to double up! Calcium is also dosed at a higher ratio than magnesium, therefore, if tap water is lacking calcium it will need to be supplemented.

First thing you need to do is determine if you even need to raise your calcium levels, as some people live in areas where the tap water has extremely high levels of calcium, therefore, there is no need to bother. A quick GH test of your tap water (water you use to fill up your aquarium with) will determine whether you need to dose some GH booster. For the record, GH 3 (53.7ppm) and below we recommend dosing GH booster. This product will NOT raise your PH

DIRECTIONS based on 50L aquarium: 

50 Litre Aquariums +/- 1/16 tsp (a pinch) of GH booster once a week (dose on the day you do your once a week 50% water change) If you are not going to do a water change after 1 week then there is no need to re-dose GH booster. 

Note: If GH is 2 or below then you can add a little more than 1/16th. Dosing doesn’t need to be 100% exact as this method is based on the Estimative Index Dosing Method. If your plants are still showing signs of calcium deficiency (see ‘Function of Calcium’ below) then gradually increase your dosing over the course of a month. Doubling the dosage would not cause any harm to aquatic life or plants, but it’s always best to start out small and gradually increase dosage amount if you feel the need as a sudden change in parameters can sometimes cause plant leaves to melt away (leaves disintegrate but roots stay intact) and re-grow again as they adjust to the new GH, particularly cryptocoryne species. WHEN DOSING PUT THE DESIRED AMOUNT INTO A WATER TIGHT CONTAINER (WITH SOME WATER) AND SHAKE, THEN TIP INTO AQUARIUM. WATER WILL GO A LITTLE CLOUDY BUT WILL DISSIPATE WITHIN HALF AN HOUR ONCE GH BOOSTER DISSOLVES. DO NOT MIX YOUR GH BOOSTER IN WITH YOUR FERTILISERS. YOU KEEP YOUR GH BOOSTER IN DRY POWDER FORM AND MIX UP ONCE A WEEK SEPARATELY. 

Now bare in mind you will only be dosing this once a week on the day you do your 50% water change. The water change resets the tank by eliminating any dissolved salt build up from the use of fertilisers, not to mention tap water already contains a certain level of total dissolved salts (TDS). If you are not going to do a water change after 1 week then there is no need to re-dose GH booster.

Function of Calcium: “Calcium is responsible for holding together the cell walls of plants. When calcium is deficient, new tissue such as root tips, young leaves, and shoot tips often exhibit distorted growth from improper cell wall formation” (Troy Buechel, 2016).  When a leaf starts to distort, it can often twist, stay small, as in become stunted, and also look a little frilly or wavy on some species.
