which pleco/cory/bottom cleaners at ph 4?
 

any bros can advise on which of the above or any bottom cleaners can survive in water with ph 4-4.5 . Need cleaner for uneaten food for altums .
thanks a lot:)

I don't think have. Just siphon the left over food out will do.

thnks. thought plecos live tog with altums in the rivers of s. america, so impression was that at least some plecos share a common parameter with altums. But I also can't seem to find any. Strange.

Are you going to eventually raise the ph?
Any new livestock added in will experience ph shock. Maybe you have chance by acclimatizing new fish gradually. Or you could try a small common pleco, those are really tough.

maintaining the ph . no problem to aclimatising the pleco but they wont survive after , even the common pleco. not sure why cos many plecos are caught in the same waters as altums :(

Any problem with Ammonia and nitrite at this Ph level?

Dont think so as altums still healthy :)

tested with kits? at this ph level, bb hard to survive.
