JoandWilly Posted February 16, 2008 Report Share Posted February 16, 2008 Just wanting to get some info on the hang-on overflows. First off i need one that keeps the water level no more (ie not 40mm) than 30mm from the top of the tank, from what i can tell the tunze ones water level will be about 80mm from the top of the tank. AquaOne and reef octopus not so sure about. Also any problems with running one? Going on an established tank so drilling not and option.

JoandWilly Posted February 16, 2008 Author Report Share Posted February 16, 2008 My tank, few changes, no more leathers, added a octopus coral and fox coral. Quote Link to comment Share on other sites More sharing options...
reef Posted February 16, 2008 Report Share Posted February 16, 2008 You can drill it. With a hang held drill. I would not trust a siphon overflow. Quote Link to comment Share on other sites More sharing options...
wasp Posted February 17, 2008 Report Share Posted February 17, 2008 Here is a link that will give you a good explanation of a weir hang on overflow. http://www.melevsreef.com/acrylics/overflow.html Drilling the tank is the most popular option and there is a reason for that, but a weir type overflow can work if you really want to do it. Note, the weir, is to make the syphon unbreakable. (In theory, anyway). Quote Link to comment Share on other sites More sharing options...
JoandWilly Posted February 18, 2008 Author Report Share Posted February 18, 2008 I dont want to drill the tank or make one, so just wanting any recommendations on the ones you can buy, for me drilling the tank is to risky and making one takes to much time.

wasp Posted February 18, 2008 Report Share Posted February 18, 2008 making one takes to much time. I suspect you don't know how much a pre-made one costs! Here is a link to a whole bunch of them, I suspect you will have to import. http://www.marinedepot.com/ps_searchIte ... w&parsed=1 Quote Link to comment Share on other sites More sharing options...
reef Posted February 18, 2008 Report Share Posted February 18, 2008 Tank looks great, why do you need a sump?? Quote Link to comment Share on other sites More sharing options...
JoandWilly Posted February 19, 2008 Author Report Share Posted February 19, 2008 already ordered one, will get it on thursday, going for a reefoctopus overflow box, going for a sump so i can use miracle mud and calupera, find nitrates are to hard to keep doing using just water changes, to many fish and feeding to much i suspect.

reef Posted February 19, 2008 Report Share Posted February 19, 2008 I would still get it drilled, i dont trust overflow boxes. If they get air into them you tank will overflow, But i quess the over flow box is a easy option. I think Hollywood is having 20% off Miracle Mud Until end March.

wasp Posted February 19, 2008 Report Share Posted February 19, 2008 find nitrates are to hard to keep doing using just water changes, to many fish and feeding to much i suspect. Your tank looks fairly new, less than a year old? It can take quite a while for nitrate reduction to really kick in, if it's less than 12 months old I wouldn't panic about nitrates yet. One thing though, if you are running an external cannister for biological filtration, this will be a large contributer, highly recommend to disconnect it. Very pretty tank BTW!

JoandWilly Posted February 21, 2008 Author Report Share Posted February 21, 2008 running a external but all it has in it is filterwool that i change fortnightly and the odd phosphate removing pouch, nothing else in it. Quote Link to comment Share on other sites More sharing options...
wasp Posted February 22, 2008 Report Share Posted February 22, 2008 How about remove the filter wool, do some large waterchanges, and see what happens? I'm always surprised how people will go to all sorts of lengths to beat nitrates, but not do the obvious, easy option. Quote Link to comment Share on other sites More sharing options...

JoandWilly Posted February 22, 2008 Author Report Share Posted February 22, 2008 only have the filter wool there as the only mechanical filtration, no other sponges etc, as of sunday when i get my sump will be removing the cannister and adding an extra 100+ litres to the tank, have got the hang on overflow so will see how it goes, if it doesnt work or floods my floor will get a new tank built with an overflow.
