So what dosing pump should I buy? I had yet another BRS doser fail on me. Grr. Time to buy something rather high quality. Opinions?? Main choices so far: 1) SpectraPure LiterMeter III 250 ml/m , 3 rollers 5 year warranty 2) Vertex Libra Interesting new product, but no long term history, and some concerns on support. 75 ml/m, 4 roller design, good Japanese motor. 3) GHL Proflux / Fauna Marin 60ml/m, 3 rollers. I am generally avoiding the Bubble Magus doser. A few reports of failing "ON". Seems rare, but is catastrophic if it happens. Plus in general seems a bit lower quality. I am generally avoiding Cole Palmer / medical, as simply way too expensive. While used on ebay brings that price down, that is too hit/miss for me. Drew's dosers are just too low flow. And of course, no more BRS for me.
