smicko Posted October 2, 2014 Report Share Posted October 2, 2014 Hi all, setting up another shrimp tank and have a couple of questions. Tank will be 3x15x18, would a 2x1x1 sump handle a pump shutdown without over flowing? I want as close to silence as i can get, what would be the best to make a sump to achieve this? I would be using dacron, macropore and marine pure spheres. What else could I use? Would there be any advantage in using other things? I have had sumps before but they ran driptrays, bioballs and Scoria so I want to step it up to the new millennium lol. I am not totally convinced on running a sump so what are some other suggestions for filtration on this tank? What is the quietest air pump around at the moment if i decided that I wanted more air. Sorry for all the questions, i normally just jump in but this tank has to be stable from day one. Cheers mick Link to comment Share on other sites More sharing options...

PETFISH Posted October 3, 2014 Report Share Posted October 3, 2014 Hi Mick, Aquael 150 are probably the quietest air pump that i know of, a 2x1x1 would probably be ok if you only use a third of it as the media section, the rest for the return pump, i have a sump in the shed (unused) i biult it for someone as a s/water sump but it could be modified easily, can't remember the measurments of hand, i'll measure and PM you about it. cheers Pete...

matt_a Posted October 4, 2014 Report Share Posted October 4, 2014 I'm not sure if a sump is the best fit for this application. As much as I despise them a canister filter is probably a better idea. To work out of the sump will be large enough just follow this simple formula: (a * b * c) / 1000 + d < (e * f * (g - h)) / 1000 Where: a is the length of the tank b is the width of the tank c is the expected rise in water level between pump off and normal running (highly dependent on pump flow rate and the tank's drainage efficiency) d is the volume of water in delivery and return pipes e is the length of the final chamber in the sump f is the width of the final chamber in the sump g is the maximum height of the final chamber in the sump before it overflows h is the minimum water depth to keep the pump submerged and not sucking in air All measurements are in cm and litres. Easy as pie? A practical example for an imaginary setup not unlike yours would be: a = 90 b = 37.5 c = 3 d = 1 e = 30 f = 30 g = 29 h = 14 So.... (a * b * c) / 1000 + d < (e * f * (g - h)) / 1000 (90 * 37.5 * 3) / 1000 + 1 < (30 * 30 * (29 - 14)) / 1000 11.125 < 13.5 The statement is true so therefor the sump would be large enough (provided the figures used are accurate.)

smicko Posted October 4, 2014 Author Report Share Posted October 4, 2014 You lost me at simple formula lol, I think I'm going with a ehiem 2213, it would be the quietest solution. Cheers mick Link to comment Share on other sites More sharing options...
Allboutthebass Posted October 4, 2014 Report Share Posted October 4, 2014 Haha wow. That took me back to maths class haha. Cause I didn't understand any of it. (Not to be offensive) From allboutthebass Link to comment Share on other sites More sharing options...

aquaholic99 Posted October 4, 2014 Report Share Posted October 4, 2014 If this is a shrimp only tank, a sponge filter would do. If you want it super quiet, use a small power head instead of air. If you bury the sponge, you will create an undergravel. If you have plants, you probably don't need any filtration. Link to comment Share on other sites More sharing options...
shakey2277 Posted October 5, 2014 Report Share Posted October 5, 2014 I use two sponge filters on my shrimp tank and water is crystal clear, i thing sponges are better than what people give them credit for, the only thing they cant do is chemical filtration Link to comment Share on other sites More sharing options...
