My Ludwigia Repens are doing good altho a little light coloured but for some reason my sag is pale. I'm wondering if it's iron or something else. The sag are a little beat up by my juvenile goldfish and swordtails but I DNT think that's the reason y they are so paleI dont use any fertilizers in my tank, but seachem flourish has a good amount of iron in it and if you're not getting the results you want you can always add seachem iron later.
The Ludwigia are striving but I've also added dirt below the sand a few days ago I DNT thing the roots have taken a hold in the dirt yet. I also added some green pro tabs but nowhere on it does it say anything about iron.
