RO water or tap water for water change?
I started my 15 GAL planted tank about three weeks ago and my LFS said I should be changing out 50% of the water with RO water every other day for the first two weeks, then twice a week for two weeks, then once a week.
I'm starting to learn about fertilizing and am wondering if I should switch over to tap water. I'm sure my water hardness is super low because I've only used RO water.
My City website is pretty unclear about what my hardness is because we have multiple sources, but if I average them it's around 230 ppm CaCO3. Not sure if that's too hard for the planted tank.
Any recommendations on how I should proceed from here on out?
I've attached my city water information for reference.
15 GAL tank
Finnex 24/7 on 24/7 mode
Pressurized CO2 system
HOB Aquaclear 20
Planted with DHG, Cabomba, Anubias, Alternanthera
No fish yet--hoping to add in a week or two once I get water and fertilizers sorted out
