So I think it's safe to say that I have a slight obsession with Brightwell Aquatics. Maybe it's their flashy packaging? Im not really sure what it is but yea... Had great luck with the Substrat in my refugium and used a few of the Xport Bio cubes in it as well. Used the Microbacter Start XLM & Quikcycl to kick start my cycle. 7 day cycle is what they advertise but it's taking a little longer than that. I'm on day 19 which is fine, I thought 7 days was a little ambitious. Ammonia had spiked and went to zero a week ago. Still have some Nitrites and Nitrates but I'm just about over the hump. Haven't really started using anything else yet. A little bit of the Ferrion for my Chaeto and Mangrove but that's all. Super excited to try everything out. I have test kits for everything so I don't over dose anything. I'll probably slowly ease into adding them so I can try to tell if any of them has made a visible difference in my corals. I'm putting a lot of faith into their product descriptions though as it will be tough to tell. Don't let me down @BrightwellAquatics!
