Hi guys,
it's common advice to increase phosphates if you have GSA. But I wonder, if anyone knows why exactly this correlation? Is it GSA not liking the phosphate in the water column, or it's about the plant health?
The reason I'm asking is that in my new tank (1 month old) I've got quite a lot of GSA on old anubias and buce leaves. I'm dosing EI method + recently I doubled the phosphates. Problem is the phosphate doesn't hold for too long in the water column: I suspect the soil (Tropica Soil Powder) buffers it. Yet it should still be available to the plants through the roots, right? But, if to battle GSA you need phosphates in *water column* then the soil is doing me a disfavour.
All plants seem to grow well and healthy, the only problem is GSA & BBA on old buce and anubias leaves.
