Re: [Killietalk] Saga with the Water Company
I use a Pur filter, essently a carbon block, for topping off and thiosulfate
for large water changes. Topping off doesn't seem to do anything, but it
may not be enough of whatever is in the water. The plants also explode when
we do a water change. I specifically asked about chloramine and he said no.
They researched it but are not using it.
