as far as i know plants dont need the carbonat part soo why even buy it? and even worse after the plant eats the calcium shit will bind to your phosporus and steal it from the plant.Not everywhere. I eat eggs quite often, and instead of a waste product, the shell is used. Reducing waste and repurposing that as a helpful resource.
But that's where the next recipe really shines. Calcium carbonate. That one is done in 2 hours not 1-2 days. See how much a couple pounds of calcium carbonate costs in your area. I'm sure you will be pleased.
I have a 5 pound tub. I use it for cleaning sometimes. It lasts so long, I have to find other uses for it.
Some large companies wont be pleased. They will want my account nuked. That's why I am avoiding using the brand name specifically.
- In Water (Aquariums & Hydroponics)
- Soft water (low KH) → pH can rise to 7.5 - 8.3, depending on CO₂ levels.
- Hard water (high KH) → pH can stabilize around 8.3 - 8.5, but it won’t go much higher because excess CaCO₃ just sits undissolved.
- In Soil
- Acidic soil (pH <6) → CaCO₃ raises pH until it reaches around 7.5 - 8.
- Neutral soil → Minimal effect.
- Alkaline soil (pH >7.5) → Little to no further pH increase.
- In Hydroponic Solutions
- CaCO₃ isn’t very soluble in neutral or alkaline water, so it mainly affects buffering.
- It can slowly increase pH over time, often stabilizing around 7.8 - 8.3 if no acid is added.
Why pH Stays Around 8.3 with CaCO₃
- In water, CaCO₃ interacts with CO₂ and bicarbonate (HCO₃⁻), forming an equilibrium that resists pH going much above 8.3.
- If CO₂ levels drop (like in an aerated system), pH can rise toward 9, but that’s rare.
