Question Sbout Gh

[kevin007]

See, i've never really cared about gH in my fish tank, now i have a new water "softner" system, the gH is reading at 15, is that really high for tropicalfish? should i be concerned?

Depends what kind of tropicals you plan to keep. Each Species has a different requirement of hardness, and it even further depends on what conditions the fish was brought up with. This water sounds to be quite hard(Definition based Very Hard): My Platy tank is at 12 dGH and it is high. This is unless you are keeping Cichlid species(See special threads) which require hardnesses 12-20. Bear in mind Cichlids are an advanced and not usually recommended beginner species. If you need to decrease the hardness and dont already have fish, simply dilute by adding less hard water.(Dont forget to condition for chlorines though).

Hope this helps.

It is fairly high yes. But if it's any consolation, here in London (UK) it's up to 19 ! Quite often referred to as liquid rock !
I keep a range of community fish - just can't keep very soft water / acidic loving fish such as neons and Rams. You might find they'll do fine for a while but I'm quite sure it shortens their lifespan.

i mainly keep guppies and cories, 15 is default, i think i can adjust it, what should i adjust it to?

Absolutely fine then - no need to adjust
