Also, aren't ph swings highly likely without any buffers? I never ever ever would use 100% RO/DI water. There are no buffers at all, nothing to keep the ph stable, that's why they sell buffers to add back to RO water to reconstitute it. I would at least keep the kh at 3 or 4 degrees. 0 kh sounds crazy to me.
i think PH swing was a myth, even if it was real, i don't think many people seen their fish died from it. they however killed them through overdose of co2.
