I told my frind to hold her bows in common city wate who is hard and
alcaline.
I hold mine in such water and there are no problems even if this
water is sometimes to high on nitrate. When it is so, I change a
part with clean rainwater. I have no disease and a normal mortality
(3 fishes in one year on a school of 40 adults and subadults). And
they are continuously spawning.
I think my friend wants to do "too much". She tries to have a
perfect pH, perfect hardness, perfect tanks... I think the better
way to have beautiful fishes (not only rainbows) is to be regular
about maintenance and water changes. The harness, pH and other are
less important. I have hold Symphysodon on a 7.5 pH without any
problems but I had clean water. Anyway, bows are more sensitive on
bad conditions and it is sometimes easyer to hold big cichlids such
as discus than some rainbowfishes. But the common point is
regularity.
So I avoid too much work on tanks because every manipulation can be
source of stress or problems (and I think that it is a little bit
idle too:)). And I'm not a good customer for petshop :) because I
have no CO2 system, no HQI, no nutritive soil from the trade
(selfmade only) and I buy my fishes only by private such as Gilbert
Maebe, Johannes Graf or Christophe Mailliet (no dead fish from them
for the moment; I wish to thank you, all the three, :)).
Have a good week
Cheers
Christian
