Welcome Steve, glad you are here! I agree with what was previously mentioned, higher nitrates and phosphates and I supplement with iodine. Because they are close and I can drive there, I have gotten most of mine from Tidal Gardens. Always as advertised, happy and healthy.
Hi and thanks for joining - as to Zoas, and this is my 2 plus years experience, is that they are a diverse bunch, have some that thrive way up high, and some that love the shadows. so it is clearly not a one size fits all approach.
but for the most par mid light and flow, nutrient rich, and some take tom spot feeding. I occasionally dose iodide, (still usually low on ICP testing)
