Brightwell AquaticsRazor Marine - Unique Systemic Fish Tank Cleaner for Marine Aquariums - Aquarium Water Treatments, 33.8 fl oz

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

Cleared one reef tank almost completely of bubble algae and sea lettuce algae! Did not do as well on another tank with gha, and seems to have affected my refugium on that tank as well. But the tank with sea lettuce and bubble algae had zero ill effects. Must be something to do with water chemistry. Will not blame the product as it did what it said it would in my first tank.

Great for reducing and controlling the algae growth in your aquarium. Make sure to stick the dosing schedule and the results are awesome. Makes it easier to vacuum out the bad algae and not have to scrap out or hand pick.
