fish fiddler Posted October 8, 2013 Report Share Posted October 8, 2013 Right o got my sump set up with 4 bays. Siphoning down into my sump getting pumped out by 4000 l/hr pump. So my problem is that I can't get the flow right and the weird thing is that I marked the water high last night and the water level drop so when I got home I marked the water high again and water level rised without me adjusting the flow. WTF. Cheers Matt Link to comment Share on other sites More sharing options...
smicko Posted October 8, 2013 Report Share Posted October 8, 2013 Is it water level in sump or tank. There could be a flow issue with the sump baffling or maybe the pump isn't fast enough or too fast Some more info on pipe and bulkhead size and number for inlet and outlet Are the bulkheads adjustable height What is the media in the sump or maybe a pic if possible.

zorbadundee Posted October 9, 2013 Report Share Posted October 9, 2013 How long did u spend changing ball valves etc my sump is 32mm of the pump and 25mm bulkhead it took hours to balance it perfect, the water can rise or fall slowly and will continue to do so until u get perfect balance, use tap as water markers on tank and sump untill u play with valves and the water doesnt move overnight or something. Keep in mind its pretty hot right now so you will lose a little water and new drift wood will asorb water. Link to comment Share on other sites More sharing options...
blocka Posted October 9, 2013 Report Share Posted October 9, 2013 Could be something as simple as it's getting an air lock some where for example where it exits the tank through the bulk heads if there's no t-piece you can get one there Link to comment Share on other sites More sharing options...
fish fiddler Posted October 9, 2013 Author Report Share Posted October 9, 2013 In the sump @ smicko I'm using one eheim intake and spay bar output which is 16mm. Then rubber hose connect to 20mm pvc with tap and spray bar and down to pump witg one way valve. And I don't know what a bulkhead is? Link to comment Share on other sites More sharing options...
smicko Posted October 9, 2013 Report Share Posted October 9, 2013 You should lower the level of the baffles (uprights) in the sump so that if your pump fails you don't end up flooded. And you could add more media without overflowing the sump. You should lift the spraybar slightly above the water in the sump so it flows freely and doesn't buildup back pressure. Do you have holes drilled in the tank or are you using an overflow setup? If it overflow its probably an airlock Bulkheads are the connection that comes in/out of the tank if it's drilled. I like to have at least twice the size of outlet compared to inlet. So I would have at least 32mm outlet for 16mm inlet to increase flow rates. As others said they do take a bit of fiddling to get flow right Hope this helps. Cheers mick Link to comment Share on other sites More sharing options...
fish fiddler Posted October 10, 2013 Author Report Share Posted October 10, 2013 It won't over flow, the last bays only got 180mms of water in it. Yeah my tank is not drilled. I cant up my inlet for my tano cause I'm using eheim spray bar which it 16mm and I dont see the point of increasing the pipe and then reducing back down to 16mm. Yeah all helping Cheers Matt Link to comment Share on other sites More sharing options...
Yoshi Posted October 10, 2013 Report Share Posted October 10, 2013 I think this maybe one that someone has to go around and have a look or u need to go to someones house to have a look at their sump etc. Smicko means up the outlet (from the tank to the sump) to 32 mm, u can leave the spray bar at 16mm Link to comment Share on other sites More sharing options...
zorbadundee Posted October 12, 2013 Report Share Posted October 12, 2013 Id leave the bar under the water level it not as noisy, but deffently lower the level in the sump. The last bay maybe empty/low but id play it safe. If you have no drilled hole/over flow what are you using a pipe and relying on the suction or Hang o the back overflow like system (both of these are harder to setup) Link to comment Share on other sites More sharing options...
