will this do?

ok , im going nano here and want approval on this sump/refugium plan for my 20 long , the sup/refugium is a 10 gallon . id like to have a single tank for this so ive thought this might work . read about refugiums i noticed its a good idea to have a slow turn over rate . im going to use a mag 7 with one of the swcs things , this way i have no power heads in the tank and i can keep the heater in the sump. anyway im still in planning stages , and gathering supplies , got lots of time , especially for coments . this was the only way i could think of to slow the refugium down with out having them in sperate tanks . i think this will add about 5-7 gallons . let me know what you think. even if im way off. thanks

are you using a skimmer? will your overflow handle that much flow?

just a couple of questions to help us get an idea.

no skimmer , ive got a over flow with two outputs and its able to go to 1200gph . im going to use valves to control the flow . main reason for sump refugium is to keep heater , do water changes , auto top off system, and keep equipment out of the display tank , and i dont want to take the extra plumbing and second pump for a closed loop with the swcs . my thought was to have the intake then return and then the refugium . this would make the refugium not have 700gph flow thru it . am i making sense

So are you planning on having lighting and macro in there? If not then you could set up a couple baffles between your water inlet and the outlet to help keep the bubbles down like this

i got it, i was just going to suggest running the skimmer output into the aquarium, thus keeping the flow even lower. and using the mag 7 with the SCWD as a CLS. with only the inlet and the two outlets in the tank.

what you have drawn should work. it is hard to guage how the air bubbles will behave though. i am thinking with how small those partitions are going to be that the bubbles will get back into the display even with the sponge. you may need to keep the water level in the sump a little higher than you think right now, in order to give the bubbles a bit longer to evacuate from the water column.

I have a 20 gallon tank i would like to use as a refugium, for my 55 gallon tank. The refugium will have to be directly underneath the main tank.

Now i haven't studied much if anything about overflow boxes and the process of getting water back into the main tank.

So i would appreciate someone telling me in a fair bit of detail what the steps are and the equipment/setup ill need.

we'll ive decided to go with a closed loop(for curculation)inside the behind the main tank refugium . ive heard its not good for a mag drive to be in line out of water , so this will alow the pump to be in water . so ill have a small pump for the refugium and it will overflow back to the main tank . this way i have a nice small flow thru the fuge and it will hold the heater . soooo. thanks for all the help , seems as though the planing stages takes the longest . got to get it right before i try . this far my set up will be a 20 long for the main tank with a coral life 130w pc with fans , 20tall fuge with 24hour 15watt pc , mag 7 on a closed loop with a squid . small pump for the fuge . probly 10lb live sand in the fuge and 20 in the main tank . 5-10 lb live rock in the fuge and hopefully 30-40 live rock in the main tank. 100 watt heater in the fuge. give me a month more or two and ill post pics as its set up . feel free to give me any tips from hear. i drill tommorrow

thanks for the input sean mcc

who said you cant run a mag in line out of water?

my cls is running on a mag 18 in line, and sitting on a shelf.

everthing sounds pretty cool, cant wait to see pics!

sjatm941 · 12-06-2003, 08:57 AM

well ive read a few post here and there about them leaking and building up salt around the seal . either way thats not the main reason for the cls in the refugium. im having a room problem with the size of behind the tank refugium.basically the tanks will be back to back with all the drilling being done in the refugium tank. seems best just to have it in there . ill try to post pics tonight if the initial drilling of the tank goes well . hehe

okay your first plan for sump/refug is great, but I would recommend these minor mods to it... Make sure the water level is as close to the lower hole for the refug as possible to prevent any bubbles. The T or Y adapter on your pvc or flextubing will allow you to have some unrestricted flow into the sump part and controlled draining into the refuge part so you can control total flow in there!

trodder · 12-14-2003, 01:55 AM

by the way Big T you need to have either 3 or 5 baffles... the 4th will not do you any good. But sjatm941, Big T has the right idea as far as getting some baffles in there to minimize the bubbles from the main intake... like I said if you keep the water line close to where the refuge drains there should not be an isuue there... bubbles will be almost non existant!
