Need some help regarding adding minerals to RO tank water.
My initial tank set up was tap, until discovering my water quality. I have been using straight RO for a little while. I have researched online, and discovered an informative article on this site as well, regarding the importance of minerals. We recently installed a soft water system. My reverse osmosis filters this same water.
Using the API 5 in 1 test strips, here's my results for my tap water, ro water, and tank water:
PH, Tap water=7.5+, RO and Tank=6.5+
GH, Tap=0, RO, Tank=0
KH, Tap=240!, RO=maybe 40 Tank=40
Nitrite, Tap, RO, Tank=0
Nitrate, Tap=40, RO=20?, Tank=40
What are my best options? I came across a product, RO right 1000gm on Aquarium Guys site. I also recall a product, Seachem Trace Elements. And I read an article on basic water chemistry, live aquaria, which states the easiest way to add minerals is in the form of a calcium-based rock. I know some suggest using part tap water, but I am assuming this would not be a consideration for me. I'd appreciate some feedback.
So far, I have one live plant cluster which looks healthy. I had noticed a couple skeletized leaves recently, which are now non existent. I have not put my gravel back in since a recent amonia spike. I have a bio wheel, which I have added zeolite crystals. The fish are thriving, for now. Will it be possible to create a naturally balanced planted tank?
FYI, current tank mates include; 1-angel, 2- dwarf gouramis, 2- swords, 2-neon tetras, and 1-pleco.
