No. Even soft water species can't survive such low GH. Back then before I knew what I was doing, I was using 90% rain water, made my GH similar to yours. I keep running to all sorts of problems mainly: I kept killing fish and I can't keep most plants alive. "Soft water fishes" means low KH thus having low pH. Get your GH up to at least 5 with the ratio of 4parts Calcium to 1part Magnesium. Fish and plants need these minerals to live.
@@M3r-5b7k not true. Gh where Cardinal tetras are found in the wild is immesurably low, below 1. You will have trouble if you are having higher GH species of fish tho. Not tetras. I will boost the magnesium however. Calcium damages the kidneys of tetras.
Perfect water for breeding angelfish too, since the eggs cant be fertizlized in hard water. I have 6.5ph and around 1 gh in my tap water.
@@Dominik-g1i oh I heard also that eggs of tetras won't hatch in water with more gh too
Oh how I envy you... my tap gH is over 20 😭
@@dumbfishtanks I used water softening resin to get to this. Tap water is about 12 gh

@@sasfishadventures9729 Well, good luck with that, I guess. Hope to see an update in a couple of months or so
@@M3r-5b7k i'll be doing regular updates for sure!
