BRIGHTWELL Aquarium Algae Remover - Controls Hair Algae, 500 ml, 17.64 oz

This is absolutely brilliant, I have trolled loads of sites and marine aquarium shops with no success with my long haired algae problem. None of them could help me with my problem. I Stumbled across this on Amazon and with in a week my long haired algae was just about gone .Just follow the instructions and you will be amazedRegardsDeano

Followed the instructions to the letter and This killed my blenny, urchin and numerous snails and both my red legged hermit crabs. To add insult to injury it didn’t do much if anything to the algae

Very quick delivery with good communication, I have been using it for 6 days now and the hair algae is thriving, not the desired effect

I’m not sure this actually worked, I followed the instructions to a T but didn’t seem to do a lot, maybe it’s worked for others but I would recommend not to bother buying this product.

Necessary bacteria for saltwater aquariums. It converts nitrite into nitrates to be absorbed by plants or your bio filter.

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.

about 2 weeks of treatment of razor + microbact clean (also from brightwell) and one big scraping and all the bubble algae is gone. Very pleased.

Eliminates my turf algae I’ve been battling with no side effects to inverts, coral, or fish. Happy customer.

We had a bit of bubble algea in our tank. Corals were otherwise healthy and thriving. Decided to give this product a try to see if it would help clear the bubble algea and save on the manual weekly plucking we were doing. Well, the bubble algea is gone, but so is a torch, a frogspawn, two acans, and a number of pretty annoyed other corals that have had to be treated and moved to a separate tank to recuperate.We even under dosed this product. Maybe it was coincidence, but daily testing of all parameters has identified no other alarm bells. Hoping that we get this stuff cleared from the water soon.I hold myself responsible for this mistake as I wasn't 100% sold and was looking for an easy fix, but don't make the same mistake I did.
