I have a 500ml bottle that I would like to make a stock solution with for micros. Here is what I need confirmation on:

2 TBS of CSM+B Plantex
1 TBS of Ferrous Gluconate
1 TBS of EDTA Iron Chelate 13%
1 TBS of DPTA Iron Chelate 10% (only because its available)

Can I bump up the 1 TBS to 1½TBS or 2TBS, would that be excessive? As a reminder, I have a 18gal. tank. I will also add 20ml of excel to this solution.

I want to dose micros a bit more than usual (a bit juicer). I've been dosing EI with little effort and great success but now I would like to see if there is a benefit to adding a bit extra.

I don't skimp on the macros and the plants has responded in kind so now its the micros turn. I'm just not sure of the amount of iron that is considered sufficient to last from day to day in a heavy planted 18gal tank. I started dosing iron daily with great success so now I would like to mix a solution to add daily right from the bottle.

One way of increasing Fe, when making stock trace solution is to reduce the amount of Plantex, increasing the amount of iron. Some people add more CSM to increase the dose of iron. This works, but also increases the level of other metals like copper. As long as you dose CSM inside the EI recommended dose you should be fine. How much stock solution are you dosing?

I hope someone will give you some actual numbers, but the following amounts added to your stock should give you plenty of iron. I personally add 3 parts CSM+B (1 TBSP) to 1 Part Fe DTPA (1 tsp) to DI water for 500ml of stock. This gives me about 2565mg/L Fe or in a 65L water column a 5mL dose is 0.225ppm Fe. I am thinking of getting Fe Gluconate (like you) and move the ratio closer to 4:1:1. I would like to boost some things higher, if I use less Plantex or not, Mn being one.

2 TBS of CSM+B Plantex (contains Fe EDTA)
1.5 tsp of Ferrous Gluconate
1.5 tsp of DTPA Iron Chelate 10%
I believe adding more Fe EDTA might add a yellow tint to the water, if nothing else. Stale Beer.

CMS+B, Fe Gluconate and DTPA Fe at 4:1:1 ratio by volume.
This will give you as pretty high Fe, but CMS is fairly rich in the other metals.
Are you saying, you want more then that? Without adding any CO2 - lights; this is "a bit juicer".

Thanks Tug, I'll give that a go and adjust as needed.
