How much MB7 are you dosing and what are your phosphate and nitrate testing at? MB7 reduces phosphate and nitrate so if those levels are already low you’re likely making things worse as Dino’s typically thrive off of bottomed or very low nutrient systems.IVe been dosing daily to keep nutrients on the up and up. Its just getting worse unfortunately. I think my next step is going to be the UV part. Blasting them into the water column and a 2 day blackout of sorts. I think my acros could probably survive a 2 day blackout. Im also ordering pods and phyto from algae barn this friday.
