  1. Re: How to roughen a screen in 5 min. w/o much effort

    It does look cool at the least. I've used a similar heavy duty version before. They stab hundreds of little holes in the paper so the steam can get behind it. As long as it gives the GHA something to...
  2. Re: How to roughen a screen in 5 min. w/o much effort

    The teeth are hardened but not as sharp as a hand saw or the like. I have an extensive range of tools at my disposal and the skills to use them.
    I never noticed that you were using the hole saw by...

    Re: LED lighting

    I think you misread my post. This light is for my corals. It also runs the small experimental scrubber in my weir with a smal amount of wasted light.
    I was just trying to show that the colour was...

    Re: ATS in weir.

    Too true. I'm thinking of maybe trying a screen at an angle with some creases to give it a terraced effect. Another idea would be to thread some heavy fishing line to create extra ridges on the...
  5. Re: How to roughen a screen in 5 min. w/o much effort

    It's a little slimey now. The surface is easily rough enough to catch the fibers on a hand towel. If it were pasta it would be al dente.
    Another good hand tool would be a handsaw with hardened...

    Re: LED lighting

    I'll get the tape out later for the dimension. Roughly 8x16inches or 200x400mm. It is a 120w unit with 1w leds.

    Just an experiment.

    I've been using one of these for years. Great tool.
    I roughed my screen up in about five minutes by dragging a serrated knife on edge across...

    Re: Deep Sand Bed

    I would guess that you are not getting enough flow across your DSB and that there isn't much living in it.

    Re: Drilling hole in tanks with water

    I did two 50mm(2inch) with a half full tank and it went fine. 10mm glass though.
    Just remember that glass wears down the drill bit at a rapid rate and the contents should not be allowed to enter the...

    ATS in weir.

    Hi all,
    This is just a small scale expeiment a the moment but I thought I would post my results so far. I hope to use what I have learned to aid in the design of my next tank and will post more as...

    Re: Built it a couple months ago, finally running

    Good effort. The butt join that has been used to join the bend will be prone to failure. Solvent cement is good but it's not that good.
    The PVC gutters and down pipes have various connectors that...

    Re: ATS will kill corals?

    Thanks for the replies.
    I have watched the video all the way through and agree with your take on it Santamonica. To me it was just proving that if you allow algae to overrun a tank it will out...

    ATS will kill corals?

    Hi All,
    I have recently been in a few debates with people about the use of an ATS. I think the concept is sound. The latest comeback was a video showing the results of a study by USF. It seems...

    Different idea for water flow.

    Hi all,
    I'm just wondering about using a wave box nano I impulse bought to create a scrubber. It isn't much use for anything else. Any thoughts?
    Looking at the horizontal type. The wave line at the...
