We recently wiped out our once established tank by treating with FluxRX. Lesson learned we’ll never do that again. We’ve got the nutrients back in check but I’d added some dry rock rubble to the sump like an idiot and now I have a major diatom issue. I wanted to buy a new Diamond goby but I’m wondering if it’s safe for it with the layer of brown all over the sand. This may not be the right forum but it’s a fish question really, not a diatom question. I wouldn’t want it to get sick or die so I thought I’d ask before I buy. Unfortunately our last one jumped out but I’ve got a good cover now
