Thanks PlantedRich for your reply. My main reason to do soil is for dry starting a carpet. However I don’t have much experience in what works best. I’m considering capped organic potting soil or Aquasoil. Among the Aquasoil options, practically all of them buffer to a slightly acidic pH (lowers KH). My question is if I use somewhat hard tap water for weekly 50% water changes for EI, would I deplete the Aquasoil buffering capability quickly? Also, would the plants be affected by a temporary shift in KH after each water change? Aside from plants, I’m thinking I will keep some snails, shrimps, small schooling fish, etc. yet to be decided. My main purpose is to grow some nice plants.
Your comments are much appreciated.
