Have just started to use RO water, reason being the desire to breed a few tetras.
I have been performing water changes with softer water for about 3 weeks figuring that a slow change will be a safe route.
But things are getting really ugly
At the same time I hacked everything pack, and rearranged the whole thing and added 20 root tabs, also
finaly got rid of all the duckweed that was covering the tank, so the light increased.
Fert level is a bit on the high side.
At first the duckweed was interesting and after a while that stuff has a mind of it's own and didn't want to leave!
A few crypt wendtii red are melting, and the bronze is just looking sort of pale.
gh = 260
Ca = 60mg/l
ph degassed = 8.0
ph with co2 = 6.8/6.6
The red temple plant has a few holes in the leaves and the tips are
small and distorted.
also a new patch of red algae that has never been in the tank before
