Good luck and enjoy the tank OP.

Make sense. I have been doing my research recently as well. I basically came to the same verdict.
Now for decided which method to use. EI or PPS. I have read up slightly up on both of them. PPS makes the most sense to me but I'm sure EI is more popular amount the guru's. lol
What do you guys think?

|Gold Finger||In an attempt to make amends for totally jacking Tylergvolk's (sorry and thank you) thread here I would like to post on the OP's original question of wether to dose the water column or not. I am no expert, a beginner really, but I have read a lot of stuff and know the theory at least, so here's the consensus. While some, especially nature types, may still advocate soil only nutrients few would say to give nothing at all to the water for the leaf intake, and most agree with the high production folks approach: dose the soil and the water column. The logic is sound. Dosing properly does not promote algae it prevents it, so dosing the water adds redundant backup. But, you say, why would my soil fert not work? The chemistry of plant nutrition is complex, dynamic and unique to each tank. Factors may exist in your tank which may block the availability to your plants of certain present elements. No one knows everything that's going on in the planted tank and redundancy is insurance. On the other hand, If you have time and experience and observe the reactions in your tank you certainly can produce fantastic results without redundancy.|

|Gold Finger||Yeah, thanks. I figured some of this out from old plantbrain posts. Will use DPTA and may use some gluconate too. Gone fast is OK for plants which suck it up fast, and good for fish which don't appreciate toxic levels accumulating. Got the theory but your practical experience is at least as helpful, maybe more so.|

Gluconate has some plus sides but definitely not for high pH/KH water.
Go with DTPA iron.

NO3 never tops 10ppm, so export is not an issue thankfully as I am trying to minimize stems. Trying to get as nice a plant look as possible despite having these messy fish in there. It is not as difficult as many think. A bit rare for folks to try is all.

Seachem Eq is 50% K2SO4, so is GH booster, the generic version.
Gold fish are great and good nutrient producers, but.......they also like cool waters..........so this slows CO2 demand and plant growth a lot...........so the nutrient demands are reduced.
Most over fed their goldfish also.
A good method to deal with any excess is adding some floating species like water sprite. Cuts the light down below, but provides excellent export of nutrients.
You basically learn to use the weedy WS as your test kit. Works quite well over time. Most LFS and local aquarium clubs like it also, so you can sell the weed.

|Gold Finger||I think obsessing on the details is a side effect of my insanity, rather than the cause. And I am finding a lot of references to fish/food Producing enough N and P but not enough K. I have just remembered that Equilibrium, of which I happen to have a jar, is 30% K2SO4, so I will dose that for a week or so and if it helps I will order some dry K2S04. Then I will start with traces and iron. The vast majorty of web advice is that with a heavy fish load I will still need to dose K, Fe, and traces to support a heavy plant mass at the fastest rate it will grow under the high end of low light such as mine. Those and some excell since I am not attracted to the idea of adding a CO2 contraption as of yet.|

I do believe in research but , I also feel people in this hobby can make themselves insane micro managing the Chemistry of it all.
I think you are right to slowly make adjustments to learn what works with your water, in your tank, with your plants, growing under your lights, with your fish swimming in water that you change on your schedule.
I feel the best tool is a camera. Take pics keep track of the progress you make. It get very obvious when you can look at pics taken say the 1st of each month.

Firstly, you make a good point about the fish probably providing all the macros my plants need, dogfish. Only someone who has kept goldfish can believe the waste they produce! My thinking was to start by providing the K+ and the traces both in order to see what non nutrient limited growth looked like then get rid of the K+ and see what happened. Now that you mention it though, I realize that I could start with just the traces first (which are more likely to be limiting) then try adding the K+ later. I would not get my answer any sooner either way. Secondly, dry vs. bottled ferts certainly is a question of economy but I don't see the sense in dosing K+ for the rest of my life never knowing if I ever really had to. I will start by picking up something in a bottle at the LFS for the sake of the experiment then order whichever dry ferts I indeed need after that. The cost of bottled traces the Seachem way (which involves one bottle for traces which last and another for traces which precipitate out quickly) is ridiculous. about $150/year vs. maybe $15 for dry!
Thank you all. This kind of help really is invaluable. I know what I am doing now.... except... I just read some stuff about EDTA iron not working so well in water as basic as mine (Ph7.8). Naturally there is a company which sells a very pretty, very expensive little bottle of "special" (ferrous gluconate) iron which claims to be much better in high pH water like mine. Any opinions on vs. plain ol' SCM+B type iron in very Basic water?

|wkndracer||As the conversation developed it reads as though K2SO4 and trace are the only concerns. 1/2 or 1lb orders on each would be a years supply for most and less cost than a single shipment of water bottles. Ratio mix trace using distilled not to introduce bacteria and dry dosed potassium is easy.|

Gold Finger - Your Goldfish are, I would think creating all the Macros your plants will need and maybe more. Plants are limited to the amount of Macros they can use by the amount of trace elements presents. Hence dosing Traces will benefit.
Keep in mind they are called "TRACE" elements for a reason. More is not better.
Both dry and wet methods work and it is more a matter of economic value over effectiveness. Dry of course is cheaper per dose. However, if one has only one or two tanks, I question the logic of owning enough dry chemical to dose an Aquatic Greenhouse operation.
