  1. Most powerhead based protein skimmers, like the Knop, CPR
    BakPak, and other similar devices using the Rio 600 or 800
    RVT powerhead don’t give you control of bubble size, so
    you control your skimmate’s dryness only by adjusting
    water height (or in some cases not at all). Putting an
    airline control valve on the end of the airline input will
    allow you to increase the efficiency of these skimmers
    significantly by adjusting the bubble size. These skimmers
    can be further improved by replacing the Rio all together
    with a Maxijet of comparable GPH and using the Maxijet Turbo
    Venturi Kit (the equivalent of the RVT add-on for the Rios,
    available for about $4.00 over the cost of the maxijet
    alone). The purpose of the Turbo Venturi Kit, like the RVT
    plate on the Rios is to move the venturi air intake from the
    water outlet to the water inlet, causing the bubbles to get
    chopped up in the impellor for a smaller more uniform bubble
    size. Combining the upgrade from the Rio with RVT included
    with most inexpensive hang-on skimmers to the Maxijet with
    Turbo Venturi Kit, and adding an airline control valve to
    further control bubble size makes these skimmers capable of
    handling most skimming jobs. Tip submitted by: Rick

  2. For those aquarists using a sump with an external pump,
    there is a simple way to keep your return pump from
    “slurping” air when your sump water level gets low.
    If your sump is drilled and uses a bulkhead plumbed to the
    inlet of your return pump, check the bulkhead and determine
    if it is a threaded or slip fitting. Ask your local plumbing
    supply house for a 90 degree “Street Elbow” either
    threaded or slip – whichever applies. This elbow will slide
    or screw into the inside of the bulkhead in your sump. Simply
    point the elbow down to create a “siphon” on your
    return pump intake. You won’t have to worry about any
    more slurping and you can run your sump level much lower if
    you desire. Tip submitted by: James Wiseman
  3. Following up on the hot tip about sump return plumbing –
    here is a tip to protect your pumps in the event of a sump
    overflow or other flood. Before drilling your sump, cut a
    small length of 2×4 timber and put this under your external
    return pump(s). Put a piece of neoprene (from a mousepad) in
    between the pump(s) and the wood. Put the inlet of the return
    up against the sump and use a permanent marker to mark the
    center of the pump inlet. This is the center of the hole that
    needs to be drilled in your sump. This simple tip will
    “take the guessowork” out of your sump drilling,
    protect your pump in a flood by elevating it off the floor,
    and it will also reduce noise due to pump vibration.

  4. One way of removing a fish from a tank is to take a
    standard fish net, square wire frame type, remove the netting
    from the frame and replace it with a plastic fish bag, like
    the ones pet shops use to bag fish.The refractive index of
    the plastic is about that of seawater, so the fish don’t
    see it, whereas they see the white green or blue nets. For
    different size frames, just use differrent size plastic bags.
    This is how I used to train pet shop employees how to catch
    fish. Tip submitted by: Bill Wing
  5. Regardless of how much circulation you have in your reef
    tank, as corals grow – especially table top Acroporas
    (see photo) – it is important to blow the detritus out from
    within the inner branches. Toward this end, it is effective to
    use a turkey baster or other such implement. Even more
    effective is a hand held powerhead directed at the coral’s
    inner branches. If you use a powerhead, I strongly recommend
    that it be plugged into a GFI outlet. If your outlet isn’t
    a GFI outlet, you can purchase at most hardware stores a
    portable one. Tip submitted by: Terry Siegel
