there has been alot of saltwater nano threads around recently but i'm afraid i have to add another one
my ph out of the tap is 7.4, i understand saltwater fishes like it more into the 8's right? well i have some 'sea shells' lying around and was wondering if i could crush them up and mix them in with play sand. would that help raise the ph? also if i were to do it how fine should i crush the shells up? so that there the same size as the sand, bigger smaller pieces?
also i have a hob filter which i was going the use for water movement, do i just remove the filter media or leave it in?
thanks
