if the fish seem alright at 7.7 then I wouldn't worry about it
maybe check the tank for clacium sources but aside from that you should be
ok with most community species
may not get lots of breeding but from local shops they should be
acclimatised at least.

Thanks for the reply. I must check for calcium sources, that's a good
lead. There are two rocks bought from the pet shop, they are yellow in
colour, and they could very well be sandstone of a porous type. I
discarded these as they came from the shop, I may well revisit this
assumption.

The pH in the shop was 7.2, so I lowered mine before introducing fish.
It is climbing, but I read that it can take several applications to
stabilize pH using the adjust solution. If I get it stable at halfway
(7.4) I'd be happy. My main concern is for the fish I have now. I'm sure
even small fluctuations in pH are to be avoided if at all possible.

Fish seem very happy, quite active, and feed with gusto once a day. Do
Danios eat algae? Mine seems to have disappeared since I put fish into
the tank.

WHats the ph straight from your tap?


pH from tap 7.1 - 7.2. This is the bit that confuses me, there must be a
base material altering the pH in the tank.

Thanks again.
