    Just saw this topic resurface this morning:

     

     


    Port Miami expansion damages sea life, state claims

    The massive dredging project to expand Port Miami is damaging sea life, Florida inspectors claim.

    The $205 million expansion is having a "profound effect" on coral, sea grass and other species, the state Department of Environmental Protection wrote yesterday in a letter to the Army Corps of Engineers, which is managing the work.

    "A fast response to this issue may minimize long-lasting impacts," state inspectors said.

    The Army Corps said it was reviewing the findings. The dredging will remove 6 million cubic yards from the port's bottom to make room for larger ships coming through the expanded Panama Canal next year.

    In a deal with Miami Dade County, the Army Corps agreed to transplant some coral colonies. But opponents claim the damage can't be reversed if the work continues without changes.

    "We believe there is a way this project can be done better and that's simply not being done right now," said Rachel Silverstein, executive director of Biscayne Bay Waterkeeper (Jenny Staletovich, Miami Herald, Aug. 19).

     

     

    Pre-Filters - ideas? anyone, anyone, Beuhller?

    in General Discussion

    I am considering DIYing some pre-filters for all of my sump related pumps (ca reactor, media reactor, etc).  In looking around, I have not found anything retail that would seem to work as well.  I would like a very open cell type foam (the really course stuff like you can get pre-made for the Mag drive pumps).

     

    Has anyone done anything like this?  The inlet pre-filter would need to have a gap around the actual intake, be easy to remove and clean, and be sturdy enough that the pump won't collapse it and restrict water flow mechanically.

     

    Sources for parts? Ingredients?

     

    I'm considering maxijet1200 and/or Sicce (0.5 or 1.0) as feed pumps (my last mj1200 died).

     

    Thanks for input!

    Pump recommendations for feeding reactor

    in Avast Marine Works

    Thanks for all the input.  

     

    The line actually drops by about 1" into the sump.  Good question on the inline valve, I have not tried removing that.  I don't see buildup in the impeller on the pump, but perhaps I should find a course filter foam for the feed line.

     

    Cheers!

    What do you guys recommend for a reliable (I've burned through 2 pumps and failed to keep a constant flow on my return line so far) for your Seabones reactor?

     

    The reactor effluent always drops to a fraction of what I set it to within days of being adjusted, so I cannot keep up with tweaking it well.  It is currently offline due to the failure of the 2nd pump I put on it (one a dc3000 with 2 feed lines and the other a mj1200).

     

    Thanks!

    Does anyone know... ?

    If you can sell MACNA tickets to another person?  I've never looked into it and another trip might supersede my planned trip out to Denver.

     

    If you can, is there a process you need to go through?

    For those using no-ip DDNS

    I just got a note from reeftronics (as my system was failing to update all day):

     

     


     
    This morning Reeftronics began experiencing communications failures with large numbers of members’ controllers.  I investigated, and saw a commonality – almost of all of the failures were with controllers using no-ip.com’s dynamic DNS service.    I checked no-ip’s Twitter feed, and found tweets acknowledging that they were having technical issues.  I wanted to send out an email to all affected members earlier, but had to travel to a client site and attend meetings.  As soon as I could, I delved more, and found out that the issue with No-IP is not a just technical issue – they were essentially shut down by court order.  More info about this can be found here:  http://arstechnica.com/security/2014/06/millions-of-dymanic-dns-users-suffer-after-microsoft-seizes-no-ip-domains/
     

    Water source question

    in Air, Water & Ice

     

     

    Actually, it does matter! If you have very hard water and that is why you are using a water softener, the RODI units LOVE softened water. They function better, filters do not clog as fast, membranes don't foul out because the water was too hard. So if it were me, I'd put the Typhoon AFTER the water softening unit.

     

    Perfect, thanks!

     

    I have a whole house (rechargeable) filter after my softener as well, so it is actually pretty clear softened water.  I was leaning in that direction, it just means a little more work to install a new port/valve for the RO.  I have an existing spigot pre-softener, but will add a post-softener one before I proceed.

     

    Thanks again for the input!

    Water source question

    in Air, Water & Ice

    I am moving my typhoon system to the basement (from the kitchen, my wife is happy!).  Right near where my water enters the house, so I have two options:

     

    1- connect the RO unit after the water softener OR

    2- connect the RO unit to the incoming unsoftened water (~225 hardness, lots of Ca, Mg)...

     

    Does it matter?  

     

    Thanks!
