Hi Steff.
Congratulation with the fry, thats a good accomplishment.
I think particular with p.linkei the lower ph can be of a little less importance, – it does not have to be so low, and also with other species have I noticed, the ph of 6 or 6.5 as you have is fine for them. They will breed also in these conditions.
Some species, such as parvulus, do better with lower ph.
And for the long term well being, perhaps it has importance.
