changing water dwc resevoir

Anyone got any ideas for changing water in a 30 gallon dwc bubbler tub?....do you know of any modifications to the tub i can make?Any / all advice / ideas are appreciated...thanks.:stoned:

Pick up a cheap pump that can be set up as an inline- run intake hose to bottom of tub, output to drain or bucket.

Next time you don't have any plants in it, pick up a bulkhead fitting and mount it as low as you can in the tub. Stick on a couple feet of clear tubing, and you have a drain- and a handy way to check nute level!

I to do as Rhiz. says sorta .
I have a valve in the tube out the bottom of my res. and I run the tube down a floordrain and don't need a pump gravity is our friend . :thumbsup:

I just put water hose adapor on the hose and put it on plants in the yard. Its not fast. But the plants will love you for it , lemons the size of grapefruit, limes the size of lemons. Roses love the stuff also, just do not over do it.

just get some type of clean hose and put one end in the resevoir and the other in a huge bucket and dump outside...

If you don't want to add fittings as suggested (fear of leaks)-----then just drop a submergable pump in the bubbler with a hose attached it. Run hose to drain or whatever.

If your near a boat shop or tackle shop you can use a bilge pump. MY bro has got a hand bige pump and we used a hole saw 2 1/2 inches and drilled a hole in the plastic top of rez. We got a 4 inch long piece of 2 inch pvc and an end cap to set in the hole to keep light and shit out. Works great, fills a five gallon bucket in a minute.

depends on where ur set up is if u were in a shed or something. u could drill a hole in the wall and install a 3/4 inch pipe as close to ur dwc as poss. and then get a 3/4 inch threaded piece to thread in a 3/4 inch adptor that u hook ur black tubing to. cut the tubing to length to be long enough to make it to the bottem of ur res. then u hook the tube to the water pump. drop it into the res and plug it in and presto out side it goes. now on the out side what i did was dug down around 2 feet and put in about a half ft of pea rock or any rock or the black tubes with hole in it would do.

then where the pipe comes out of the wall u put an elbow going down and put the length u need on it where it's going down to the rock. and then elbow on that and put a piece about a ft or so so it won't drain right next to the building. then fill in the hole and no more buckets and no more hassle. or if u want like i did run a line under ground to your garden but u would still have to do the same from above with the rocks and stuff to drain proper.and u might want to install the clamp over the pipe to make it snug to the wall

never mind....
