KH2PO4 is mono potassium phosphate, it gives the plants P and more K. I didnt realize you were already dosing both.

Theres no quick answer for that haha. Google macro and micro nutrients for plants and start there.
I hadn't even though of doing that. I'll look that up along with macro and micro nutrients. Thanks

Does anyone have a link that would explain how plants utilize each fert? Or rather, the effect of the ferts on the plants directly?

And yes, pick up some KH2PO4 and a trace mix like Plantex CSM+B.

I have been wanting to do that actually. I wasn't planning on a planted tank when I initially set it up, and jumped into the plant aspect with a little too much excitement lol. Gonna get my 5.5 set up so the fish I hav will have a place to live while I rescape this one.

CO2 is a little better, glad you have a good steady level. Replace it before it runs out - unstability in CO2 is also a big invitation to algae.

Low doses, because you're not high light and compressed CO2, are all that is needed for maximum plant growth even if your 20 is packed full of well-growing plants. And I'm glad to share whatever I have picked up in the last 14 months.
Again, thank you very much! I know the risks now, and have been paying extra attention to fish health, tank parameters, and algae growth. So far no change! The plants on the other hand are actually growing and looking healthier. This could be coincidence of course....
I change one bottle every week. So one bottle will run for two weeks total and then be replenished. Works for me.
And I'm gonna try lowering the dosage a little. See what happens. 'You are a scholar and a gentleman'

And I already dose Nitrogen, Phosphorous, Potassium and trace elements. I also dose an API product which has iron and potassium sulfate. It was the only iron product I could get at my LFS....very slim pickings. As far as Co2 goes, my DIY makes 1/2 bubble per second at a surprisingly steady pace.
I appreciate you helping me out though! We will see how this goes I guess...

Oh and why low doses? I do weekly water changes, and have read it's not bad to have too many nutrients in the water....but there are so many conflicting arguments out there! Just curious what your reasoning is

Gotcha. I'm still doing weekly water changes in an attempt to get rid of the algae completely....if that's possible, and with my new UV sterilizer hopefully tht will help too! But in the meantime I will try to figure out a balance for dosing. So kinda works out for me

Someone who wanted to embark on that journey with a small tank would have to use Nitrogen, Phosphorous, Potassium and trace elements, and use them all, in the correct proportions, very small doses. I wouldn't advise it. It's for high light and pressurized CO2.

Test every other day and see how the plants and fish are reacting

I had one for a while. Brought him back cuz he was damaging new plants that hadn't rooted yet. Oto cats that I have are too picky of eaters though imo. I need something that's gonna eat about anything. A friend actually almost got me a royal pleco....don't know why he didn't lol
