hi all is anyone using one of these do they really work and wot would be best stuff to use mesh wise mike


Hi ,I don't use one yet but I have been thinking about making one so I have done a little bit of research and the mesh size I have seen mentioned loads of times is 7 mesh . 7 holes to the inch like this one http://www.ebay.co.uk/itm/280964156...eName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 .Don't know if you've seen this but it's a calculator to work out the size of screen and how much light ,flow etc .It's all based on how much you feed irrespective of stocking or tank size .This is the new thinking in ATS. https://public.sheet.zoho.com/public/cdm2013/ascalculator-xls-1 HTH


just made one up today, just now waiting for casing to go round it

was spraying out of sump

read quite a bit and they keep saying T off return pump and the inlet, but then have read you need 350l per inch on the drop, so 4 inch deep needs 1400lph

I'm using my d+d pump off my reactor

will see how we get on


Hi ,everything I have researched regarding running an ATS suggests that getting the flow correct for your given screen is critical.What I have read is you are best setting the pump up in a sink or bath with your chosen size pipe set to the height it will have to pump and set it running and get a container of a known size ie 2L container and time how long it takes to fill the container several times and take the average . Once you know how long it takes to pump a given volume you can work out how much it will pump per hour . Do not try to work off of manufacturers flow diagrams as these are often unobtainable due to bends ,size of pipe etc.If your pump is very powerful you will obviously have to fit a valve but the above method will give you an idea where the valve needs to be positioned for the correct flow. Most problems people have with ATS 's is usually down to either flow or lighting .Get these 2 right and your laughing.HTH


I ran a scrubber on my tank, until I broke it down. It was very simple and successful, keeping NO3 at around 2ppm and PO4 at 0 on Salifert kits. I was feeding the tank pretty heavily with frozen, flake, pellets and my own frozen concoction. My first effort is detailed on my pages here and my not so well documented second scrubber which was cleaner and more effective.
