    How to handle chlorine in my DIY auto water change?

    PH rise in water cup

    Hi all, I'd agree with @Wookii & @Zeus. and I suspect it is just the difference between the CO2 : O2 ratio in tank and glass. In the glass the water is 100% saturated with dissolved oxygen and at equilibrium with atmospheric CO2, in the tank there is either less oxygen or more CO2. That is...

    Converting% Ratios in Fertilizers to Ppm

    Hi all, That makes it really easy, the percentage on the bottle is the same as the ppm of each nutrient supplied, because the various dilutions are all factors of 10 and cancel one another out. Yes, so we have nitrogen (N) and we want to convert that to a nitrate (NO3-) value, bearing in mind...
