DanielRES1180: Yes, I have a very old Hagen AquaClear waterfall filter but it works perfectly. It has a regular mechanical filter, an activated carbon bag and I add one Ammonia Remover. I think this is ok for RES. Am I right?

Nop, water was very very clear.

Yes, but I made the water change two days ago with no bubles. Just this evening.

All the time.
Now I changed 50% of water with bottled water and my little RES opened its eyes under the water again

Previous water or something was irritating their eyes but now it seems to be ok. Of course, the bubles disapeared with the water change process.
Thanks God!
Next days I will be watching very closely the aquarium in order to detect any problems with the water.
Thanks a lot for your kindly help.
