SUPERBAC worked this time. I believe it was cycled in 3 days. I used r/o water, r/o right, blackwater expert and superbac with a lava rock and a soft rock with m-l gravel. only 10g I put a betta in on day 3 then 2 danios on day4 my paameters are soft- 20, ph 6.4 and the big 3 are 0. For those of you who followed my r/o panic posts, i added more r/o with no BWE. MY experiments w/ tap,r/o and BWE steadily suggest with the soft r/o i need only half dosing to MAINTAIN my ph @ 6.4 . I love this r/o. It is much easier to manipulate than hard tap, at least for my purpous.As well i will be adding freshwater essentials, for fish health and i understand that by adding a touch of AQ salt that helps fish to develop thier own slime coat! did it b-4, but never really knew why it worked.
