If you measure your KH and GH with a kit that reads one degree of hardness per drop of reagent, the real relationship between 9 dKH and ppm is 180 ppm, or even 200 ppm. When you measure something...

How consistent is your CO2 concentration in the water? Is it the same an hour or so after the lights come on every day? Many of us have seen that allowing the concentration to vary widely, like...

It has always appeared to me that Seachem's Flourish line of fertilizers was designed for low light tanks. Their dosage recommendations have always seemed to be much too little for high light tanks....

"Too much" CO2 promotes algae? I don't recall reading that before. Has anyone here found this to be true, where the high CO2 was used along with non-limiting dosages of the other nutrients?

CO2 needs to be about the same level every day, but it doesn't matter if you shut it off at night. It is what it is during the photoperiod that needs to be controlled. If you are doing your nitrate...

Before doing anything else, just do a crude calibration of your nitrate test kit. It may not be reading right, for some reason, including your technique.

I found if I dose about 2X the EI dosage for KH2PO4 I don't get any GSA. I have no idea why it works, but it has worked for years for me.

No. Fertilizer for terrestrial plants isn't the same as for aquatic plants. It is so easy to dose the right stuff for aquatic plants, so why dump other stuff in the water?
