what does hardness do to your fish??

[petitericeball]

because my hardness is at like 17 drops of the gh stuff and i was wondering if i could use it for my dwarf gourami pleco molly and corys...

17 drops of gH stuff, really doesn't tell us much as there are dozens of different test kits around. What you need to do is check with the instructions that came with the kit to find out what 17 drops actually converts to in terms of gH.

Most common tropicals can live in fairly hard water - it is not ideal for many.

I would guess (just a guess, of course) he's using the type of test where you keep adding drops of a solution and mixing until the water changes color (such as the Aquarium Pharmaceuticals test, which I use). If it is the AP test, then each drop equals one degree of GH, so that means his GH is 17 degrees, or ~300 ppm.

That's fairly hard water, but for info, mine is 19 (with a pH of 7.8 and a KH of 10), and my dwarf gourami and many cories do fine in that water.

I think I still have 3 different types, and none of them are the same.

If it is 17 gH that is pretty hard, but most common lfs trops will live in that.

Unless you are doing laundry GH doesn't matter, unless it is reallly extreme. More of a concern would be the higher PH that tends to come with a high GH.

whats angels hardness my gh is 3 whoo-hoo

 

[petitericeball]

my kit is the freshwater master kit
every drop=17.9 ppm
so i can use my tap water??
my ph of my tap is like ...7.4

so the equation is 17x17.9 for the ppm..
what the heck my water upstairs is softer then my water on ground floor wtf is up with that??
so its 1x17.9= 17.9ppm
and the bathwater in that room is 11x17.9
so my upstairs water is much softer then my other water...
