The best and cleanest dry fertilizer available.
Having tried Niloc-G fertilizers and noticing a level of impurities I thought I’d give GLA a go, glad I did. Salts were super clean. Their potassium was absolutely amazing as well. Micronized salts from GLA are the way to go.

GLA Ferts
I have used GLA ferts (I dose EI) for years and they are excellent! Just now had to restock because the powder lasts forever! Trust GLA!

Its perfect if your looking for pure Kno3.
If your looking for 1lb of Kno3 for pennies on the dollar this is it. I used the elementary calculator they had and I easily made my own DIY recipe. Piece of cake!

Did a good job of bring up Nitrates
Due to excessive plant mass relative to bioload, I was getting algae in the presence of low nitrates. I needed some fertilizer salts to raise my nitrates. This worked great to hit the target range on my aquarium.

Working wonders for my Reef!
I dont have a planted tank but I do keep reef tanks and word is out that GLA carries the best pure Nitrate for reef tanks around. I gave this stuff a try and the results have been amazing. I mix 1 teaspoon to 100ml RO/DI. I dose 5ml in my tank raising my nitrates to about 3.5ppm. If your looking to raise Nitrates in your reef tank this is absolutely the stuff to use. Thanks GLA for providing excellent salts for my reef. I also use Kh2po4 in my reef and the results are equally as rewarding.

Great for establishing no3 in ULN reef systems
This product worked great... mixed 45 grams of powder with 500ml of ro/di water. I had zero no3 in water and po4 was around .06 I was dosing 15ml. In my 300 gallon frag sustem morning and night until I got around 2-3 no3. It also lowered my po4 to about .04 for a few days, if the kno3 had anything to do with that, Maybe... Product worked great and corals look nice... Plus, I have enough to last 5 years... lol... don’t hesitate buying if you have a ULN system... It will get you where you need to be

Reliable Macro Fertilizer
I have been using this product for years now. It used to come in a zip-loc bag but now with it's own container it looks really nice. Not only is it affordable, but it makes a great improvement to any planted tank. Highly recommend it.
