Great looking tank! The driftwood will have a lowering effect on the pH, but it seems you may have offset it by the substrate and trace minerals will help. The pleco will certainly appreciate the driftwood for sure.
Tank looks great but in my humble opinion you dont have anywhere near enough rocks. The Mbuna are going to start kicking the haps asses and they wont have any where to go. Again jmho
Thx I will get one more large hole rock in a week or so , I have to make the drive to pull that off I think thy will be cool to then But thx again for reply
