Guys, I currently use seachem fertilizers for my plants but thanks to a friend, now I know that Greg Watson is much, much cheaper.

So I'm getting ready to make an order and I need to know what is what and what I should be buying:

Iron Chelate-Is this Iron?
PMDD Pre Mix-Is this Flourish Comprehensive?
CSM+B Plantex-No idea what this is, anyone?
Mono Potasium Phosphate=This has to be phosphate right?
Barr GH Booster=What?
Calcium Sulfate= :confused:
Calcium Chloride= :confused:
Potasium Sulfate=Is this potasium
Potasium Nitrate=Is this Nitrogen
Calcium Nitrate= :confused:
Calcium Calbonate=Is this Carbon, Excel?
Magnesium Sulfate=:confused:

If anyone can answer feel free please.

I also saw that they don't have instruction on how to mix the ferts with water. Any help would be greatly appreciated.

Hater, why Greg does not have directions for what is what and how to use it is beyond me.
Maybe he has some reason that is being kept a secret.

I have had the same questions as you for a very long time.

I hope that thread above was very helpful to you.

To partially answer your question, the riddle of this hobby is why there is so often NOT a straight answer.

Maybe Greg's reason is because people seem so have SO MANY DIFFERENT ways to fert their tanks?

Best of luck.
And just to let you know you may get very different answers to the same questions in different forums.
Find what works for you.
Or in my case, slowly learn THEM ALL and then decide which makes sense for you.

Enjoy the hobby.

I am using the Potassium Nitrate, CSM+B, and the Potassium Monobasic Phosphate with the EI Light technique and my Melon Sword is turning Red!


This is so much easier! I am rotating the three ferts, dosing 1 of the 3 per day so that I end up dosing each twice per week. Spoons are in the Ziploc Twist Cups. No more looking up on charts and measuring!
Greg, I like doing the dry ferts. I just did a significant water change (5gallons out of 27 Gallon tank) and tried to make sure that I got as much of the carbon out of my filter pads. The DIY 3 Liter Soda Bottle CO2 is doing its thing very well.

My question is about my water and the dry ferts. I don't really know what green water is, but my water is starting to get 'cloudy'.

Is this caused by too much dry ferts? (The water in my 10 Gallon where I use the same dry ferts is crystal clear.)

Hoppy, I am still using the light schedule that we talked about last. Should increase or decrease the light? (sorry if I posted these questions in the wrong place).
So a large amount of newly recharged CO2 (DIY) and CSM+B could possibly cause this. Okay.

I will do another large water change (5 Gallons out of 27 Gallons) and hold off on ferts until it stabilizes.

When the light is off, the water looks greenish. When the light is on - the water has a whitish 'haze'.

I assume from the phosphate already in the water from the day before.

More to learn.
