Vodka dosing.. HELP!

[TimT]

Are you just using Vodka or are you also adding sugar and vinegar?

Only Vodka but I'm thinking of changing to Probidio, only Biotim and Bio Digest. I don't know if someone has any experience with the method

how many times a week are you doing water changes? Maybe start doing 25% weekly to manually export the nitrates.

I wouldnt start switching methods all of a sudden - may end up doing more harm than good. Cut back on the vodka dosing and check your ro/di to ensure TDS is at 0.

I do about 10 to 15% of weekly water changes, I may start doing 20 to 30 My ro/di it's at 0ppm I have a TDS meter, thanks!

just in case, have you calibrated your tds meter recently?

Prodibio is a good product.

As for VSV method, the recipe I was using is 750ml Vodka, 175ml White Vinegar and 3.5 Tablespoons white sugar. I would reduce the amount you add and then slowly increase it.
