View Full Version : Adding phosphate

I am in the process of setting up an experiment and I need to add phosphate to the water. Does anyone know of a method to add PO4 in a measurable way? Thanks.

Ok, so I searched around a little more and found a product. I found some potassium phosphate on amazon, and it has good reviews with people using it for aquatic and terrestrial plants. Link: https://www.amazon.com/Monopotassium-Phosphate-Soluble-Hydroponics-Aquariums/dp/B00TZTYK2Q/ref=sr_1_2?ie=UTF8&qid=1473290442&sr=8-2&keywords=potassium+phosphate. What do you guys think about this? It seems like it would work.

Interesting! Can you tell us more? Is this experiment going to be on your reef or planted tank? What do you hope to learn/accomplish with this experiment?

I think I will use the potassium phosphate. I want to add it in a measurable way, which I have online calculators for. Michael, I am not using either of those tanks. I am breaking down my old freshwater planted tank, and I am going to use it for my experiment. The experiment is testing different levels and ratios of nitrate and phosphate on different macros. I will make a thread soon for it.

I've notice a increase of Phosphates when I dosed Aquavitro Fuel.

Same here. There are other products such as seachem's flourish phosphorous (which is just potassium phosphate) that raise phosphate also, but the 2 pound bag of it on amazon was cheaper compared to $10-$20 for a bottle of seachem's item.
