kent kalk

[Madreefer]

Years ago I added it to my reservoir and it never really did dissolve. Worked much better when I used a kalk reactor.

the directions require mixing it, then let sit for a few hours. Afterwards skim the crust on top, put middle water in ato, get rid of mud on bottom. Hmmm

I would follow the instructions.

Mix in RO water and let it sit until the water is clear.
Then syphon off the clear mix water to just above the sediment and add the clear mix to your top off.
