Micro Stock Solution

Wow, lot's of iron. I do like it but, wait for the more experienced guys/girls to advice you.

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.

Are you saying, you want more then that? Without adding any CO2 - lights; this is "a bit juicer".
