Adding Sera Super Peat is it ok?

I purchased some Sera super peat to help my super hard water. Is this stuff safe for plants? I noticed that it says it combats algae, does this mean it saps vital nutrients?

Here is a description from the box.

"sera super peat releases valuable humic acids and trace elements well-dosed into the aquarium water. Depending on the present water values sera super peat will lower carbonate hardness and pH value. The pH value is kept constant in the slightly acidic range for a long time. This makes fish from tropic softwater areas feel much better. sera super peat inhibits growth of fungus, bacteria and algae. Use sera super peat instead of sera super carbon. sera super peat is suitable for water conditioning in breeding setups, also in case of low carbonate hardness (KH). "

Peat is peat, it will soften the water and turn it yellow.

Does not hurt, makes some thing slike pH/KH measurement harder, but if that is not an issue, then it's fine, it can and was used as a DIY cheap method vs RO water and blending.

Overall, RO is the way to deal with high KH.
Vista, CA gets it from the canals or from wells if it's hard water.
Central valley well water is very hard typically.
