What would be the best way to recirculate between two reservoirs of the same size-40 gallons without adding alot of heat to the water? Each res has a via aqua 2600 740gph pump flooding each 3x3 tray. Will I need another pump to recirculate between reservoirs or can I set it up somehow to use one or both of the existing pumps without adding a 3rd pump just to recirculate>?
Two reservoirs - how to recirculate between them?

this is what i would do if i think im reading this right....
i would put 3 holes in each rez... put gromets in there.... use 1/2 inch tubeing and connect the rez's together... so now you should have 2 rez's with 3 different tubes connecting eachother together.....
now get 2 pumps a pump in each rez.... use 1/2 tubing and connect the pump to one of those gromets.... Now do same thing in other rez to a different tube then you connected the first pump in the other rez to....(hopethat reads correctly lol)
the third one will make sure that the rez's always stay at the same hieght and one pump doesnt fill up one rez and make it over flow..... hope that helps....

The reason is I added a 3x3 tray and they sit side by side. I am thinking that by recirculating between the 2 reservoirs I can:
1) Increase oxygen content if I can get some kind of cascade effect as the water goes from res to res.
2) It will keep my nutrient solution well mixed
3)I dont really have a problem with temps in the res now. Im at 22c which is about the limit I want to be at but I think my overall temps will go down with recirculating.
AM I wrong to want to do this and should I just run two seperate trays?
Thanks Poopy, its just what I needed. I appreciate your help and that what im going to do.

SO IF IM HEARING IT RIGHT YOUR TRYING TO RUN ONE RESV INTO THE OTHER TO CREATE CASCADE EFFECT?? TO INCREASE OXYGEN?? WELL LIKE I SAID IF IM HEARING IT RIGHT I WOULD EITHER ONE OF TWO ME PERSONALLY WOULD JUST USE ONE RESV RUNNING BOTH DRAINS INTO SAME RESV AND GET AN AIR PUMP WITH STONE OR JUST BUY TWO AIR PUMPS .....THATS IF ALL YOUR TRYING TO DO IS INCREASE OXYGEN??

runinng 2 40 resies is gonna mean you have 80g of water in the room, which is going to add a bunch of humidty. this is coming from a dude who;s got 2 4x4s and 2 40g rezies
If you are worried about o2 content of the solution & want it to remain well mixed, either get that solution bubbling with airstones, or get a little (under 200pgh) pump to constantly circulate.
do you have 2 3x3s & 2 40g rezies?
you can use the 1 40g rez, recirculating, between the 2 trays. this will save you on nute costs, relieve you of some extra rh, and make things a little but easier to work. I suggest having the reservior sit underneath the trays (so when the trays are draining you get that waterfall/cascading action
you will need 2 pumps (obviously) set at different times, but you can have it set up so after pump A floods tray A from rez R. when tray A is done draining back into rez R, have pump B flood tray B.
anyhow, just another way to look at things.... hope you get your room set up and rocking.

Yep, Greyskull is right on, thats how I do mine too. I have two 115g reservoirs (with lids) and I flood 4 4X4 trays with each. Each reservoir has 3 big airstones, split off a single big 140lph air pump for aeration. Each reservoir has 4 800gph pumps, paired together with a tee (in case one pump fails, the other can still work.) 2 pumps tee together to a single line, then tee off again to split to two trays. By splitting this way, I can centralize the "upper" output tee between the trays equally, so they fill evenly and at the same time. I put a shutoff valve before this upper tee so I can shut down a pair if needed.
Using two programmable timers (and a 5-way splitter out of each timer) I can run 4 pumps per timer, so 4 trays (2 per reservoir) fill at the same time. THey then turn off those pumps, the system drains back to the reservoir, and a few minutes later timer #2 kicks on the other 4 pumps, and fills the other 4 trays.
I like this also because I can have one side of the room running lower nutes (for smaller plants) and split the other way, one half can water longer or shorter if needed. The other half of the room gets hotter nutes and floods longer for the bigger plants or different strains. More reservoirs DO let you run multiple strains much easier, but its up to you.

Not reading all of this technical advisories, but I'd keep a nice clear connection for fluids to traverse back one way then pump the other direction. But man if one gets clogged, then you pump and overflow a rez.
I would really suggest going with 1 rez. You can use 1 pump for both trays, or simply use 2 pumps.
2 pumps would also be better for low water levels. As long as they don't activate at the same time (offset timers), you will need less water, as only 1 tray floods at a time. This may be useful in the later weeks of flowering, when your plants are really slurping the water.
