Default All you need is Love...and IRON! A must see...

From my own experiences with aquatic plants? I agree with Dr.Novak. All that other stuff others say to mix in a strange brew?..no need. No Phosphates,no Nitrogen and certainly no Ammonia, no gravel additives or special substrates.
Watch this..go over his other vids as he takes on other fertilizers and methods and why.
I say..Iron gluconate is all over other forms of iron. What's really great too? It's a fertilizer that is NOT used by algae..it goes to the plants. Unlike tablets and all that mess that will give you green water. Iron might even make fish healthier..good for red blood cells,perky active fish.
Tell me what you think,My mind is open.

Sounds like iron was the MISSING nutrient in your case. Plants DO still need N, P, K, Ca, Mg, etc. Without a suitable mix of those, adding more Fe wont help. The others may be plentiful in your water and/or fish food. "Not needed" in your particular tank is not the same as "plants don't need ..."

I made it through a few minutes of all that BS video.
If I dosed no NO3 & no PO4 my tank would be filled with dying plants and glass covered algae.

Everything must be true on the web, especially YouTube.

And, algae also need iron to grow. Iron in a bioavailable form has to be dissolved in water, so it is Fe+++ or Fe++, and chelated iron does that, too. One possible way to make life difficult for for algae is to keep bioavailable iron away from algae - keep it in the substrate instead of in the water. I'm dreaming up ways to experimentally demonstrate this.

I guess you have to try it!..What more can I say? I even posted a scientist who's kept water systems for 30 years..he cites studies he and others have done..he uses lab quality instruments and you can see his readouts. He's even like more hard core waterplantaholic..using canisters of Co2.I havent change my pumps,substrate or even fish..yet since November I've gotten growth like never before and I imagine what Co2 would do on top of this. On the other hand that Sword looks darn impressive and at this rate its going to be centerpiece of the tank.

Everybody's tank is different. When someone propose a quick easy answer, you'd have to be skeptical. Sure you can try it out but expect it not to work.

Kevin Novak's tank appears to have a fairly dense fish load: several adult angels, cories, SAEs, plecos, danios, etc. He's probably getting all the N and P he needs from fish food. He's right about ammonium being the "preferred" form of N for aquatic plants -- they can use it more efficiently than nitrate. Diana's book explains this too. BUT ammonium is of course toxic to fish at far less dosage than nitrate.

Actually, there is an easy answer. Put dirt in your substrate and you don't need to do anything except feed your fish.

You have to understand...dirt in the substrate only feeds for a short while...everything the plants need is eventually dissolved and what's left is as inert as gravel..only looks cool because its so fine.
Aquarist do NOT have feeder streams or even hilly banks where nutrients are drawn by gravity and hydrolysis and capillary actions to keep the soils in that river bank or pond with nutrients that flow onto foliage and roots of aquatic plants.
Potting soils has a very short life underwater..works great for a month maybe..then if you don't dose..the plant will begin to show..needs. Of course it can work too well..and there you are with algae on everything.
Basically your better served studing hydroponics..and also served to keep in mind unlike the brute force of heavy nutrients for terrestrial plant roots and growth..we have much lighter feeders who are immersed totally in what we add to the water.
Just remember when you read of Osmocote or tablets what those ferts do when runoff from farms to aquatic plants in streams...nothing but wads of algae and dead water plants.
I would add maybe you use near sterile RO water or local waters have far too much this and way not enough that..that's what you need to compensate for.

Have you ever tried ordinary dirt as a layer in a substrate, where the roots can get to it, but little of the nutrients leech into the water? No doubt the dirt will eventually run short on some of the nutrients, but for a year or two I doubt that it will run short. I rarely keep a tank set-up going unchanged for longer than 2 years, so I have no experience with longer use of dirt in the substrate. When you also have fish in the tank, and feed them well, the nutrients that run short first, are constantly being replaced from the fish waste and excess fish food. Nitrogen is the one that I believe goes the fastest.
