It only takes one dose a week, or even less if you are using the Flourish Comprehensive, to provide too much iron. Some plants can store certain nutrients, and iron is one of these. Java Fern is a slow-growing plant and that means it needs less light intensity and fewer nutrients, so excess of either can cause problems. A good cover of floating plants can usually solve any light issues for this plant, but too much fertilizer is something else than has to be controlled. All that iron is not good for any fish either.Alright I'll stop dosing iron don't know if it matters but i only dose about once a week also I was wondering if it could be a macronutrient deficiency my tank doesn't have many fish and the snails eat any excess food plus I do 50% water changes once every 2 weeks. Would this affect it in any way?
On the GH, that's fine. I assume this is measured as ppm so 75 ppm equates to 4 dGH and that is sufficient for plants with respect to calcium and magnesium so there is no issue there if you continue the Flourish Comprehensive. In crease your water changes to once each week as this replenishes these minerals too.Sorry about that, I use flourish excel its liquid. Also my gh is 75 or on the little bottle it says soft.

Now on the Excel, once there are fish in this tank do not use this product. It is glutaraldehyde (and water) and this is a powerful disinfectant so intense it is used in hospitals to sterilize surgical instruments, in embalming fluid, anitfreeze...this does not belong in an aquarium where it will get inside the fish. They won't die (unless you overdose in which case this will kill all plants, fish and bacteria, it is strong) but they will be weakened. Some plants, esp Vallisneria and some mosses, will die even with the recommended dose on the bottle.
You really don't need it anyway, as there will be sufficient CO2 from the organics decomposing in the substrate.
Mine actually doesn't have any of that in it it says its ingredients are polycycloglutarcetal and water on the website it says its safe for fish. I''ve done 50% water changes once a week and stoped dosing iron for several weeks now but it doesn't seem to be helping also on the bottle of "flourish comprehensive supplelement for the planted aquarium it says that macro nutrients can be bought separately and are not provided. I don't know what wrong with it still unless plants can get diseases too.
