How much iron to dose?

[bluedragon]

I don't have test kit for iron, I have Ferrous Gluconate (powder). How much should i be dosing on 55 gallon planted tank with 130 watts light, and i have lots of swords? Also I have 15 watts UV running 24/7. And also is there any harm overdosing iron? what would be the symptoms of overdosing iron if there is any?
thank you

Good luck ODing the iron. You'll hit non-limiting fast and head right into luxury without any trouble. I do about .75ppm, others do twice that. Keep in mind that you need to add CSM+B to the Fe gluconate levels. Fe gluconate is about 12.46% Fe so add about 8x the weight of the desired level you want. You'll have to talk to someone else about how many g/tsp it is.

I'd mix about 1 tablespoon of CMS+B and a tsp of Fe Gluconate in1 liter, dose 15mls 3x a week.
Plenty of traces for a 55.

I dose arround 2.0 ppm iron with csm+b and don't see any overdosing problems with fish or plants

I finally ran out of Seacham Traces and Iron, Time to go with CSM+B and Ferrous Gluconate. I will be mixing up the solution as Tom has advised, I read somewhere but I can't find it anymore, it said to add Excel to the solution to preserve it and prevent Fe participation in solution. How Much Excel should I add to the solution?

I know when adding HCL to add it first and allow to sit for 10 minutes to prevent precipitates. I do not know if this practice is necessary when adding Excel, but it couldn't hurt.

I add about 25 mls per liter.

Not sure if Excel has anything to do with preventing precipitates. This would be the first time hearing that.
