Excelente loja , entrega rápida, preço justo... e o Red slime é um ótimo produto!!!

Very good product.

Must skimmer up place

works well. keep the skimmer running along with extra aeration using an air bubbler. this will get rid of a lot of organics, skimmer wont stop skimming. I did a second course after 48 hours and that got rid of cyano completely from sand bed.

works very good . Skimmer goes crazy for about 3 to 4 days . Be sure to ad much co 2 . for your fish ( very important )

After using it for the first time, results are better the espected!! Great product

100% works
