Hi Guys, I just got some Epson Salts and Chelated Iron from the big green shed and can't seem to find out quantities on a forum search. Can anyone refresh my memory on the quantities to use? I have 400L of growbeds and 1100L of water. Cheers, Idzy |

Dunno about the Epsom, but the general consensus on Chelated Iron seems to be 1 slightly heaped teaspoon per 1000L. |

What are your reasons for the "epsom salts" Idzy... And what's your pH?? |

Thx Mr. Damage. Rupe, this is probably going to sound stupid, but I thought the epsom salts would help, I remember reading they are good and safe. I have just planted some zucchini to give them a go (I realise it's the wrong time to be planting them, but hey I'm having some fun), and they are doing really well, but have some yellowing on the leaves, which I thought could be iron deficiency, but then again, I thought maybe it was something else like magnesium, after talking to the gardening chick at the big green shed. pH has been off the scale (7.8-8.2) for a while now and I lost quite a few fish over the Christmas period, while I was on holiday. I came back and brought it back down to 7.2 at the moment, but I feel like there is a 'buffer' or whatever pushing it back up. Any thoughts would be appreciated. |

epsom salts are great for Mg but over time can build sulfates in a system without enough water changes. It seems prudent to use them in soil watering or in waste water going to out to drain to waste systems. I use them and other Mg forms as the water around here is very deficient in minerals, so clean the tap water won't even turn on my auto on EC meter. I really don't know yet what for of Mg would be best in an AP system I was working on that until I was rudely interrupted in my research recently. I was testing mag stearate but it seems form reading its not as absorb-able but possibly not harmful buildup wise. |

Can chelated iron be added to the water without damage to fish? I have been spraying plants with chelated iron dissolved in water to counteract yellowing leaves and it seems to work well. |

Added to the FT or foliar feed are both valid methods. You'll find that you will need much more when added to the water volume to raise and retain @ the preferred 2mg/L. Foliar feed I think is much easier and no test kit is required. |

Careful about adding too much iron. I overdid it and turned the water and my goldfish black! I had to do 4 water changes in a 250 gallon ft and now the goldies all have black highlights! Actually they do look pretty cool! I finally did just a knife blade tip for the six beds and the veggies and tomatoes greened right up after a few days. The upside is the black water helped knock off a bunch of algae! |

How much did you add, Sails? I think the rule of thumb is around a spoonful per 1000L from memory. |
