Very high GH does what???

While I see that GH is good, mine reads over 600 at the outside tap. By doing 50/50 tap and undersink R/O I've now gotten to around 360. Well, what effect does too low or too high GH have on the plants/fish. I believe that plants/fish need the naturally occurring minerals in the water but is too much detrimental to some plants/fish? Hope this question makes sense.

My fish seem to be doing fine; I see all my vals shredding? quickly in my tank, but other plants do well, IF my platys leave them alone!
Other parameters are KH<> 80 and pH<> 7.2 Low to medium light? (24" Coralife 2 bulb T5NO and Marinelife Double Bright LED 11 hours/day) in a 36 bowfront, no CO2, weekly liquid ferts and 3 times per week Excel and DIY Osmocote capsules about every 6 weeks in a Walmart No-Scent Kitty Litter substrate.

And let me take this opportunity to say thanks to the many members who often go well out of their way to help everyone.

Thanks,

Some day I hope to understand at least 20% of what I think I know. And maybe someone can explain the other 60% to me.

You're having trouble with your Vals because you're dosing excel. GH should only really effect shrimps.
