New Planted Tank (GH/KH Q's)

Hi guys,

I just started a new planted tank and have just measured the KH and GH, the kit uses drops to calculate. So, KH was 3 drops or (3x17.9=53.7ppm is that right?) and Gh was 5 drops or (5 x 17.9=89.5ppm).
Is this acceptable for plants and fish? The tank is only a little over a week old and I was told I could add fish when I noticed plant growth, so I bought a couple of mollies and some neons, one of the mollies has died but i'm not sure if it was the time it took me to get the poor little bugger into the tank (5 hours)
The PH is pretty high, up around 7.6 but i've been told to let that alone and worry about the GH/KH, so that's what i'm doing

Plants all seem to be doing well, no major die off yet, but it may be too early.

Here is the tank if you would like to check specs etc...

Thanks in advance for advice/input.
