Cyano, Brightwell MB7 and Vodka

[Oscar]

Thanks gqlmao for that balanced response.

Over the past 6 years I have been rarely happy with the appearance of my tank. Either it was algae, dirty sand, cyano, or brownish corals.

VSV seems like a very easy and inexpensive dosing regime, if it does not pan out then nothing lost.

Nope really nothing to lose, it VSV is a very good method for nutrient control. I use it for the reason I can feed like a mad man and still keep nuisance algae in control. It just has to be used carefully and the results will come over time. I am hoping you get the results you want with this method. GL

I am now 4 weeks into vodka dosing. Last Saturday's tests showed the first reduction in nitrates, phosphate has been 0. On Saturday I will conduct my next test and hopefully I will see another reduction in nitrates. My current dose of VSV is 2.2ml per day, increasing at 0.5ml per week.

On Monday we are heading out of town for 4 weeks and my tank sitter will be feeding the fish and dosing vodka every second day. Although I have not gotten nitrates to zero yet I have suggested that he dose only 1.0ml per visit in my absence.

Am I being too conservative? I can always start increasing vodka dosing when I return, if necessary.
