I have two tanks..
29g 4 months since cycle
Aquarium Gravel
No Live plants
LED lighting
Ph at 7.6 which is my tap water after conditioning and waiting 24 hours..
75g 1 month old, seeded from 29g
Play Sand Substrate
A couple small live plants
Many pieces of driftwood which has caused the ph to drop to 7.0...
Which also leads me in to the problem of my PWC on the 75g.. The Ph is at 7... My tap after conditioning is 7.6.. With a 50% PWC.. I am assuming it will jump to 7.3.. Is this bad? Is RO water neutral at a Ph of 7.0?
As far as the diatoms.. Don't do anything with them? Don't scrape them off the sides or anything and they will eventually die out....
