    Skimming conversation

    Energy does not equal electrical potential. Show me a possible electron migration path from some place, though the water and back again, and I'll be happy to discuss the effect of said electron motion on the water. So far I've not seen a proposed electron path that obeys the laws of physics...

    Any ideas for a dcent DIY Skimmer

    Okay- I can agree there. However I'm not convinced that the venturi on a needle wheel has a high enough performance to work when buried under 4' of water. I've read that one manufacturer moved their Eheim pumps up higher on the large skimmers specifically due to the poor air draw when they...

    Don't Trust a Suction Cup.......

    Hey Hawke- Sorry to read this! One thing I can suggest to everyone- Put a needle-valve on your RO/DI feed line, and a timer on the pump/solenoid. Adjust the needle valve to a trickle, then adjust the timer so that in a 24 hour period, it can only barely keep up with evaporation. For the...

    65W PC into 55W setup

    I've not tried it, but in general a 55watt ballast will not be happy trying to drive a 65w bulb. If it works at all, it will be running too hot, and no doubt fail prematurely. The other possibility is that the ballast can't provide enough current, and would not drive the 65W bulb at full...

    Up grading help

    Mike- I agree with you right up until you say not to use a skimmer. I would suggest that a UV and Ozone setup would not be more effective than a skimmer, unless it was so big it was dumping ozone in the tank, and the cops kept coming by looking for a grow operation. :) A pair of big skimmers...

    Sneak Peak of new tank!

    Some of the MR-16's have the filter built in. My track-lights have a UV lens that comes installed in each light. They did have some "blue" party lights in the 50W MR-16 bulb. Maybe one of those for each pair of the 6500k bulbs would help balance it out. Zeph

    The whole electron charge idea from a spinning, electrically isolated impellor is a bunch of bull. It fails the most basic believability tests- Electrons are not generated from scratch, the wheel can't be spinning off electrons without pulling them from some place, and there has been no...

    Sneak Peak of new tank!

    Thanks for the link- People have talked before about using filter glass in front of these. How about a light blue filter on them to absorb some of the yellow wave lengths? Then you might not need actinic at all. Since you are not growing animals with the light, the exact PAR is not...

    Poll: What Type of Digital Camera Do You Use?

    Technically only a Single Lens Reflex camera is a SLR. If it has a mirror (or pentaprism) that moves out of the way to take the picture, it is a SLR. Granted there are cameras that are "SLR" like, but let's not go redefining acronyms. ;) Zeph

    Any ideas for a dcent DIY Skimmer

    Yep, that sounds good to me. I believe that there is a sweet spot though- Too short and you get too wet of foam, too tall and you just have a tall tube with crud on the walls. And I think it depends greatly on the air volume too. .5 CFM though a 3.5" tube does not need the height that 2 CFM...

    Skimming conversation

    Think about it this way- A water pump (Eheim, etc) that moves water, and as a byproduct pulls air in though a venturi, is not going to be as efficient as a pump dedicated to pumping air. Even at the same measured air flow the water pump has to spend energy moving water. While you can come up...

    Poll: What Type of Digital Camera Do You Use?

    Love my Nikon D70- Just picked up the SB800 for Xmas, and need to get some time on it. VERY nice though. : Zeph

    Skimming conversation

    I think Mike has a good point here: Some manufactures claim that their designs are "plankton friendly", which is a bunch of crap. All venturi run the water though a small area of high pressure- Anything traveling along with the water gets a burp of higher pressure as they go though it. Not...

    Any ideas for a dcent DIY Skimmer

    Well I’m both a manufacturer and a long time hobbyist, so I'll throw in my two cents. Tubes are used partly for looks, but mostly for manufacturing ease. It takes more time to build a four sided box, flush trim the edges, round them over, then flame polish them, than it takes to cut a tube...

    Thanks all- after following those steps I still had to log in a second time on the equipment screen, but then it let me in OK. Thanks- Zeph

    Equipment Reference page not letting me in-

    I am logged in and can post and all. I go to the Equipment ID Reference link at the top of the page- http://www.reeffrontiers.com/reviews And it gives me a list of items. I can drop down one level, no problems. When I try to open an item, it claims that I must be a registered user to read the...
