Posted	enclosed sump system
21-01-2007 21:04 by Sumo2001	was building an enclosed sump system for my 250 gallon tank whaty do you think any changes needed? http://s28.photobucket.com/albums/c210/sumo1964/?action=view&current=sump2.jpg
21-01-2007 21:29 by -Rob C-	ive got no experience with sumps though, so cant offer advice
21-01-2007 21:43 by trik	i take its a sump for trops not marine.
22-01-2007 05:20 by Linda Chenapa	is there a differance ? ,i thought they both did the same job ?
22-01-2007 08:19 by trik	yes linda you dont want sponges in the sump as it will cause major nitrate issues, what you want in a marine sump is DSB deepsand bed or MM mirical mud, along with live rock rubble and a good algae scrubber such a cheato.
22-01-2007 09:49 by Alan	For freshwater you want as much biological media as possible sao the above from a filter perspective would work although I'm not quite sure how an enclosed sump would work, how would you clean it for one and how would you manage the water pressure on the seals from 250 gallons of water as to be enclosed it would have to be pressurised. I would forget the sponges as well just fill it with alfagrog the last thing you want is the thing clogging. For marine there are a number of options and they are all based around the eco method. Deep sand bed this is a bed of mixed grain size sand that provides a medium for burrowing worms and inverts and must be at least 4" deep. The inverts stop the bed from going totally anaerobic and enable to removal of nitrate. Algae scrubber/miracle mud filter this is the traditional eco method. It involves the sump being lit 24 hours a day to prevent the caulerpa growing in the miracle mud from going sexual. Again this does a fantastic job of removing nitrate and phosphate with the added bonus that the media slowly disolves releasing trace elements into the water. Both of these methods or a combination of the 2 together is ideal for keeping traditional difficult fish plus it enables the best water quality to be maintained. All the filtration on the tank would be carried out by such a sump as well as the appropriate amount of live rock in the tank go for water turnover in excess of 20 times per hour preferably more.

22-01-2007 20:19 by Sumo2001	hi its for a freshwater malwai tank its having a flange and removable lid so will be pressurized will be run using a 3000 lph inline newjet pump was going for a 5000 lph pond pump but thought thius was to much hope to create loads of nitrates as am also haveing a coil denitrator buit 8" diameter approx 22" tall will also be using 2 eheim pro 3`s as well got 2 tunze 6080`s for water flow so hopefully with the sump filter and rest of filters should have good water quality my last tank had an open sump and had zero nitrites and ammonia only trouble had with nitrates as approx 100 ppm !!trouble is my tapwater is over 50 ppm anyway!! cheers for help will let you know how i got on
22-01-2007 20:21 by Sumo2001	so how many times per hour turnover should i be looking at for my malwai tank please? will be stocked on the heavy side once all filters are upto full speed also is it worth fitting my fluidized filter as well?rated at 600 gallon tank?
23-01-2007 09:32 by Alan	Calm down flipping heck the pro 3's alone will be more than sufficient. As far as water turnover goes I would think of lake malawi as an in land sea the lakes are so big that they are actually tidal so using stream pumps is a very good idea and will maximise gas exchange. I would forget the sump altogether go for the 2 eheims add the fluidised bed and the nitrate filter as you say it will be more than enough if I had the inclination to go this made on filters I would be keeping rays not malawi's.
23-01-2007 19:31 by Sumo2001	cheers alan only making sump as got all the stuff i need anway pump filter media sponges etc etc only thing i need for denitrator is the pipework as again got the biowheels and pipe work do you think 2 denitrators would be fine?as again got everything pipe etc just need th epipe for inside wbhich is only about £15 got rest anyway . am a bit mad on filters jsut am lazy and found you can never have enough filters really like sumps as there cheap and really good just had trouble with them smelling for me!!! kept tank lovely and clean just smelt thats why changed to current tank and set up would like to keep rays but me thinks there harder to keep than malawi`s take it you couldn`t keep rays with malawi`s anyway though have got 2 mollies in there with them from the daughters tank she broke down cheers again alan for advice
24-01-2007 09:35 by Alan	I wouldn't keep rays with malawi's if the rays could survive the harwater and high ph they would probably eat all of your malawis. The filtration your planning would be sufficient for keeping rays though. They are much harder to keep than malawi's but a billion times more fun especially at feeding time.
