Do you have chlorine or chloramines in your tap water? How do you avoid shocking your fish or plants?
The reason I posted the review is because the present product I use, detoxifys heavy metals at the low values normally found in tapwater. Now depending on the user, it can be a good thing or a bad thing. For those who use a product the does the same, may want to check the ingrediants on their fertilizers. A lot of these fertilizers contain heavy metals. So if a aquarist does a water change from the tap and then adds the dechlorinator that also detoxifys heavy metals, and then adds their fertilizer, then the fertilizer is compromised and will not provide the necessary nutrients as stated on the bottle.
One manufacturer advises to wait 24 hours minimum to 36 hours before adding any fertilizer when using their dechlorinator.
In my case, the available iron, potassium if any and other heavy metals use by plants thats in my tapwater, then I want to keep. So the Review will show which dechlorinators detoxify heavy metals and those that do not. So the aquarist has a choice under their individual circumstances.
