Ben Posted January 13, 2006 Share Posted January 13, 2006 Hi all, Reading some of the posts started today got me thinking. Is 2000lt per hour into a 6x2x2 enough for a colony of Tropheus? How many times do you turn your tank volume over? Are you doing it for water quality or for water flow? Link to comment Share on other sites More sharing options...
parrdog Posted January 13, 2006 Share Posted January 13, 2006 Both. I have the 3 canisters for water quality, plus I have the returns pointed at the surface for increased agitation. I also have a powerhead for water flow, it also is pointed at the surface. This gives me peace of mind that my Ts are getting heaps of oxygen. Definately an advantage on these hot days we are having. Jamie. Sorry, forgot about the turnover. My tank is 470 litres. My canisters do 3000l/h altogether, my powerhead does 2000l/h. So, about 10 times an hour, but canisters never run at the output printed full of media so I guess it's more like 8 times an hour. Link to comment Share on other sites More sharing options...
sycho zebra Posted January 13, 2006 Share Posted January 13, 2006 On my tank with approx 380L i have a sump with a 3400lph pump, a 2217 eheim cannister filter and an aqua clear 300 and i might be putting a power head in to so i can run a diffuser.

trofius Posted January 13, 2006 Share Posted January 13, 2006 I would like about 4-5 tank turn over/hour and i would love it to enter the tank in like surges like from waves... Link to comment Share on other sites More sharing options...
Ben Posted January 13, 2006 Author Share Posted January 13, 2006 By the sounds of it I am way to little. Only 3 times an hr or so. Link to comment Share on other sites More sharing options...
MoliroMan Posted January 13, 2006 Share Posted January 13, 2006 Ben.. i think u should be ok provided your nitrate levels are at a minimum. The key is to do regular water changes. U may want to add a canister for clarity. However, i did hear someone say that too much water movement may reduce breeding levels - are they pulling my leg?

MoliroMan Posted January 13, 2006 Share Posted January 13, 2006 How about adding a UV filter? Do u guys think it is necessary? I have heard it reduces the fishes ability to fight infections if placed in a tank without uv filter? All my fry are kept in tanks without uv filtration.

parrdog Posted January 13, 2006 Share Posted January 13, 2006 If that's the case, I'm stuffed (referring to the water movement thing). Jamie. Link to comment Share on other sites More sharing options...
MoliroMan Posted January 13, 2006 Share Posted January 13, 2006 so am my mate!!! Maybe do an experiment and turn all but one of your canisters off! Only joking mate....! Link to comment Share on other sites More sharing options...
Nigel Posted January 13, 2006 Share Posted January 13, 2006 I think about three times an hour is plenty. There is always the danger of over filtering. I think water changes are more important, there is also the danger that by over filtering people get a bit slack with the water changes. Link to comment Share on other sites More sharing options...
