Hello and welcome to El Natural. It's good to see that you are excited about doing a planted tank, and a 10g is a great one to learn with. I have to tell you though, that your plan is not an El Natural tank. I think if you add all of those elements and aren't dosing CO2 and using high lights (for super fast plant growth), probably all those things aren't going to be taken up by the plants. If not, then it's just hanging out in the water column at high levels. There's a danger of iron poisoning (metals and layerite aren't needed at all with soil). Shrimp are very susceptible to metals in the water. Even plants that use iron can be poisoned from too much. I don't know how to quantify that, but metal and layerite sounds like way too much. You could also have a bacterial explosion with added dead leaves which would lead to high ammonia and nitrites. That could foul your tank and kill your fish. A natural tank gets it's own fertilizer slowly and naturally from fish food/mulm. If you want to add like 1/2 an oak leaf after soaking it for a week to feed the shrimp, it would probably be ok to put it in on top of the substrate or in a food clip. On the one hand, I think it's great that you want to experiment and have read lots of cool things others have done (one at a time and with established tanks probably). But if you try to put it all together, I think you'll be disappointed. I'm wondering if you've read the how-to here at El Natural. That would help you a lot. All you need are plain dirt, a gravel cap, maybe a bit of shell, 20-30 watts regular flourescent light for your 10 gallon, and some water movement from a small powerhead. You can buy the CFL equivialent for whatever fits in the hood, just go by the 'replaces a X watt light' rating. A UV filter is good. A sponge filter could be useful the first 4-6 weeks, but after your soil adjusts to being submerged, it might be competition for the plants as far as using the fish's natural ammonia for fertilizing. I'd wait to add the shrimp until then, too. Looking at your plants, I wonder if you really want a high tech set up. That's a whole 'nother ball game. Maybe that's the direction you are really headed, and that's cool too. They are lots of work but beautiful. I'd say try a real El natural tank with easy low-mid light requirement plants and lots of them to start. #2-4 Glosso, HC and Stargrass aren't well suited to EN. Salt isn't good for your plants. It's generally recommended for people who keep fish without plants. Your proposed inhabitants don't need it. Good water conditions are met by plants growing well. Plants will be your primary filter. It's hard to figure out what advise fits regular planted tanks (higher tech) and what advice is for El Natural. And most people have experience as fish keepers before planted tank keepers. I didn't so had to learn it all with my first beta nano tanks. This forum and DWalstad's book helped most. If you go with EN, it's really the easiest. I think that's what most of us here like about it. Sorry to bear bad news; I myself have been disappointed and frustrated by a bad start and had to redo. I wish you well.
