    Questions about ro filters

    in General Discussion

    Posted

    I have a used .. i belive it is a spectra pure unit at work. It will need a new membrane as we have pushed thousands of gallons through it. The best rejections rates as far as I can remember are 2 to 1. What you need for good rejection rates is higher pressure. Something in the 60-70 psi range. We used a small booster pump for this.

    I'm curious why you would want to drink RO water? It doesn't taste all that good and lacks a lot of minerals that we need.

    Anywho, I'll ask my partner if he wants to sell the RO and booster pump. We expanded our rain water collection system so really don't need to use the well eater anymore (and the Troutdale aquifer kind of scares me) :(

    Foam during new tank start up

    I would be more worried about the PVC that has jb weld on it. Depending on the location, I would not trust jb weld to seal PVC, especially if you have nice flooring in your house.


    Wait.. you joined the pvc with jb weld...
    No, no, no!!

    I would ABSOLUTELY drain it and replumb it. I thought you jb welded the bulkheads in or something. You can not in weld pvc. I mean, you can, but absolutely should not.

    The only thing I am aware of that causes foaming in falling water is surfactants. Those chemical compounds in soaps that break down surface tension. Epoxy does not contain surfactants.

    I would buy a jug of activated carbon and run it until the foaming stops, replace it and run some more

    Guest speaker ideas?

    For whatever it is worth, I really enjoy talks that focus on how to better manage aquariums, recognize certain patterns and avoid crashes. I guess, talks aimed at those that don't have 5 or 10 years of marine experience.

     

    The quarantine talk was awesome!!

    Thanks Pledo. I have been testing alk and calcium daily. This post is kind of proof how there are sooo many variables to things and how they should be done based on those variables. Sure, if you have a fowlr or softie tank.. why bother?
    I have a two month old 60G tank with several sps, a decent sized clam, and 3 montipora.
    So for me, just starting to dose two part, i have to test daily to see what things are doing. Plus I have to kind of prove to myself that this whole notion of "a year old tank is required to grow sps" is simply a case of people not understanding the boom and bust cycle of bacteria in new tanks and how that equates to initial stability and eventual stability as each successive cycle is closer and closer to equilibrium.

    Just the other day I was reading some post "bacteria in a bottle.is nonsense" they need to eat or they will be all dead".

    Huh, there is someone that didn't take AP bio.

    Anywho. Good times, just a lot.of testing right now

    But where is the challenge in that!  Besides, even if you start there, how long until you get the next "big tank".  I put that in quotes since big becomes a contextual thing around here :shock:

    yeah, what he said.  I think I need to get a bigger tank so Sean will come down and have a beer and look at it.  :tongue:

    aww but then you don't get the pretty color corals! Get a nano do a weekly water change and do softies and lps and hardy sps and you're done!

    Nothing in my life is Nano... and I like it that way :)
