I won my original 72 bow in a raffle - I recently replaced it due to scratched glass on the front. I agree with previous posters - they look great, but I have several cons. If starting over I...

My former 72 bow had scratches on the curved glass - they are expensive tanks so I decided to try buffing it out with cerium oxide. Spent a lot of time on it, tried different tools, etc. I'm not...

Quite rare for the two (kH and GH) to be that far apart. If both are coming from limestone-type rocks in the area then they are nearly equal. Your numbers suggest something else dissolving. Makes...

Baking soda works great for raising kH. Much cheaper than aquarium-specific products. If you plan to use CO2, it will react with the crushed coral, raising your GH so I'd advise just using baking...

Yes, it will still be available as HPO4. The only other thing I see is that you are destroying some of your kH.

I'd suspect the pH meter on the controller - that's likely the problem. Have you calibrated it recently? That is far more likely to be incorrect than the drop checker fluid.
