My newest L4 ATS

Welcome to Algae Scrubbing Join our community today
  1. Just picked up a used L4 (at least I think it is an L4) yesterday. It was very dirty but I have managed to clean it up fairly well and hope to have it ready to be installed by the end of the weekend. My plan was to install it on my 150g cube but I am thinking that it may be a bit to much for that size of tank. What do you all think?

    Should be fine - post a pic, I'll tell you what unit it is. Or send me a message and tell me who you got it from & I'll look it up
     
  3. Here is a pic after I cleaned it up. It turns out that this scrubber came from the same guy that originally owned the L2 that I picked up a while back. Having that information actually solves the mystery why my L2 had extra valves and such that came with it.
    I will pm you the seller's forum screen name if you wanted to update your database of where your ATS are at.
    Thank you,

    yup that's a Rev 3 L4
     
  5. Bud,

    I finally got around to installing my L4 but soon realized that pump I am trying to use to feed my skimmer and the L4 simply does not have enough flow. Before I go and buy a new pump, I was wondering what your recommendation would be for flow on the L4.

    Thank you,
    Tom

    You want a pump that is capable of around 400 GPH after head loss. The head loss is A) the vertical distance from the top of the water to the slot pipe (not from the pump to the slot pipe, only the vertical rise above the surface) plus 24" for the slot pipe and fittings. Then you look at the head loss chart and find a pump that can deliver roughly 400 GPH at that head loss.

    You don't need that initially, in fact you want to start only with enough flow to coat as much of the screen as possible without getting to the point where the flow "arcs" across and the flow is heavy on the far end (opposite the pump). You can increase over time if you need to (you may not need to) so with that in mind you could find a pump that gets you between 300-400 GPH at your head loss level, and you will probably be OK with that for quite a while.
     
  7. I certainly appreciate your help and thank you for getting back to me so quickly.

  8. Well life got in the way and I never got around to setting up my L4 until a few days ago. When I did, I ended up using a Rio1400 as a feed pump running without restriction. I tuned it with the 1.5" output valve and only have about 3-4 drips coming out of the emergency overflow. Needless to say that it runs near silent.
    When I purchased the scrubber, the former owner sold it with some acrylic mounting rails. They didn't work for me so I opted to make my own mounting rails out of aluminum c-channel and angle. I cut it to size and riveted it together.
    I am still working on wire management but for the moment it is staying dry and I have put it off until the weekend. [​IMG][​IMG]

  9. Made my first harvest today. My guess is about 3-4 oz. [​IMG][​IMG][​IMG]

    Very nice! Be careful how aggressively you harvest though, it looks like you probably scraped most of the growth off completely. Next time, I would just do a rub with your fingertips while rinsing and leave in place whatever doesn't come loose. You're not in any danger of root dying when the growth is short

    By the way that is probably one of the most perfectly even carpet of algae growth I've seen!! Great pic
     
  11. Thanks! I was super excited when I seen that amount of growth in such a short period if time. My last scrubber was a DIY version and it did well but in all the years that I had it online, I never got this type of growth or results. Especially not in only 9 days from the very start!

    Additionally, I must give kudos, as they are certainly warranted and deserved. So, my hats off to you Sir, for the evolution and manufacture of one amazing piece of equipment.

    My sincerest thanks,
    Tom G
