marina mix yung blue. 150 more or less kay kathrina. sa mizrach, yellow bag lang meron dun (zuhl) 125 yung isang bag. yellow gamit ko dati, then blue, then bioR, blue ulit, now back to yellow, pinakamura eh.
i wouldn't know the exact effect of those though. i use natural seawater kasi eh. kaya lang minsan, di pa one month stocked, kailangan ko na gamitin. so what i do is get 5 gallons seawater combined with 5 gallons fresh, stay for 2 days. hyposalinity. patay ang ich
after two days, saka ko lang gagamitin ang saltmix to raise the salinity. aerate for two more days, pwede na magwater change on a weekend.
