Default Does pH matter?

Leigh,

Interesting thread, however my lighting is not anywhere near that much.
I have a 36W CF and its a ~20 gallon tank. So not even 2 W/Gallon.

I need to get myself a testkit to measure KH, but even then i dont think
it would be my plants: i have had this problem for a while, and the tank
has been until recently quite poorly planted.

Sigh..

Thanks for all the help guys and gals,

when i get myself a testkit, i'll hassle u with it again

cheers

We have really soft, high pH water out of the tap here.



Have you tried leaving some tapwater in a cup or bucket overnight, and seeing
what the pH is then? Often, the pH right out of the tap is only temporary.
When the water reaches equilibrium with gases in the air, the pH may change.

Also, do you know what your KH is?

If your KH is low but your pH is high, the problem might be your plants. See
the thread called "after planting, pH 9" -- it discusses what can happen if you
have too much light over a tank.

You don't say how big your tank is, and you don't say if you inject CO2. But
if you have more than 3 watts per gallon and don't inject CO2, pH is going to
be a problem. It can even kill your fish.
