if the risk of softening the water is minimal, it's still not a good idea, because the wood will leach organic compounds in the water and no Rift fish will be happy with those, regardless of changes to pH or hardiness ....my experiences with tanganyikans are that even if they're not harmed by it, they still do better if you avoid wood altogether.
Why I agree with your statement, it will obviously depend on the initial alkalinity of the water, which in this case, we do not know.

In terms of water chemistry Lake Tanganyika is a pretty strange, and if the water was low enough in proton (H+ ion) acceptors for the addition of the weak acids (H+ ion donors) (from wood) to make any difference, I would suggest that the water is already unsuitable.
Point taken, but I think we are talking at cross-purposes. My point was that if the small volume of organic acids from the addition of wood is enough to overwhelm the carbonate buffering and alkalinity of the OP's water, the water is already unsuitable. As the OP had obtained Lophiobagrus brevispinis, with the aim of breeding them, I assumed that they were happy with the suitability of their water for these fish, and had some idea of its parameters. The other point is that Lake Tanganyika's water is pretty strange, and for example whilst I have something close to Lake Malawi come out of the tap (but a bit colder), not many people will have anything close to Lake Tanganyika (possibly unless they live in N. Island New Zealand?)I meant the OP's aquarium water, rather than that of Lake Tanganyika
I have to say I do not have any experience with cyclops or know anything about starting a culture or what not, could anyone help with that? I'll have to take a look around to the LFS's has I'm not sure of the cyclops.
