Review: great product ive gotten this multiple times now with awesome results - love this product! its helped me out alot and i make sure to keep it on hand all the time and i do mantinence doses 1/2 times a week in an acropora dominant system. ive seen the reviews with ppl saying its killed things in their systems and if that really is the case you either over dosed or added at night time or your alk isnt stable to begin with and this product made that issue even worse for your system. if you dose early in the day and have stable alkalinity/ph you will be fine 100%. your system naturally drops ph at night just like the ocean does. this product will also lower ph initally after dosing and you dont run carbon reactors while using so it stays in the water columb so yes if you dont take those few things into account you could 100% kill some of your inhabitants. very good product water becomes crystal clear within minutes literally. filter pads will be full of gunk by the following evening
Review: Works great! but be mindful… - So some of the reviews saying it killed all their corals, It won’t as long as you follow the directions thoroughly and keep a close eye on the water parameters!!! (Can’t stress this enough) you’ll be alright, When a large amount of algae dies it releases nitrates which results in a nitrate spike which can kill corals and fish if not tended too. I would highly suggest using this with some SeaChem Pristine to help keep nitrates manageable. ( or similar chemicals) And more water changes are always recommended.
