That light is a power compact bulb light and the Coralife version has no reflector. It will produce about 20-30 PAR, or low light, perhaps very low light. You need to use low light plants, like...

More information will help. Is this set up now, so it delivers the CO2 to the aquarium? Do you have a bubble counter in the system? Have you checked the whole thing for leaks by using a mix of...

I agree, except that plants take up nutrients more easily/quickly if the concentration in the water is above some minimum value. (I'm pretty sure that is correct, but I may be wrong.) I am...

If you mean, how to avoid the swing between CO2 concentration from day to night to day, that isn't important at all. At night the plants are not in need of carbon, so very little needs to be...

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.
