Evaporation during hyposalinity is really not the issue people imagine it to be. Keep in mind that you would need to evaporate about 3 times the volume of water at 1.009 to get a 0.001 change than you would need to evaporate to get the same change at 1.026.
A lid is generally completely sufficient to keep the salinity in the therapeutic range.
With the bicinctus I didn't even have to add RO water between the weekly water changes.

Ohh. I’ve read that with hypo there’s a big margin for error and a top off would keep it at therapeutic levels, that’s why I never really tried it but you are right, the risk is much greater for the fish with a top off and it’s kinda being lazy on the keepers part. Thanks for the info, now I feel it’s much easier than from what I’ve been reading. [emoji106]
