Hello everyone, I'm new to these forums and need help with shutting off my pump based on the water level of my secondary tank. I'll explain more. 1) Pump in sump needs to shut off if water level in above tank or main tank reaches a certain level. Optional: An alarm or light come on if this...

I have built my own tank - originally I had a Fluval Fx5 External filter 1500ltrs but because water level in sump is lower than the top of filter, filter was constantly sucking in air and stopped working. So I need to replace with a sump pump. *Attached photo's* Main Tank = 191 UK gallon -...

Hi, I recently bought a 210lt tank with sump from my friend to replace my smaller tank. It is setup as a tropical tank and at first the water levels were fine but now the Ammonia and Nitrites have started to spike and doing frequent water changes doesn't seem to be helping. Could it be that...

So I just upgraded to a 150 gallon tank with a built in overflow and now everytime I try to feed my fish the food flows straight towards the baffles, gets stuck and eventually goes down the overflow. Is there a trick to feeding where the food stays in the tank? Do I just have to turn my sump...

I have a 125 gallon reef with about a 5 1/2 ft head. In my sump I am using a CA4000, not enough circulation . Can anyone suggest a better submersible pump to work in my tank? Price matters Guch

So I have 33 gallon tank with a eshopps overflow box 300. I did custom piping that leads to the sump I made from a 10 gallon tank. I was running a sicce syncra 3.5 pump for return but it is too strong i had to close the ball valve 1/2 way and noise to much vibration. I did custom PVC pipe for...

My sump is low in water and I don't want to run the pump when It is dry unfortunately today was Christmas and I couldn't buy more water to top it off. Can I shut off the pump overnight? Everything else is working, Powerheads heater, etc the filtration will be off for about 9 hrs tho until the...

Finally setting up my refugium/sump. Concerned if siphon is broken or blocked, display tank may overfill. Please advise product to turn off pump if tank starts to overfill. I was going to buy another Auto Topoff unit (ATO) but they are programed to turn off after 3 minutes (17 max).

I don't have a pre drilled tank but would like to use a sump. Are the over flow boxes safe to use, or what happens when the power goes off and the sifen is lost. Do I need the sump in the first place. I'm getting conflicted advise and need to narrow it down. My tank is a 1 week old reef tank.

Ok, so I've searched all over and can't find a discussion exactly about this, but if I just missed a post that answers the question - Sorry! Please just post the link. :) My tank isn't drilled to overflow into a sump; I'm siphoning water and using a pump in the sump to return to the tank. The...

Hey everyone, I have a recently set up 55 gallon saltwater tank. I am planning on putting in a sump with a refugium. If you have had success with a sump you made please share. Also, I would like to know what is a good overflow, and sump pump for a 55 gallon tank. Thank you in advance, Kenneth

After 5yrs of dealing with a SUMPLESS 75g...finally took the plunge and bought a nice used 180g with dual overflows I'm relying on a local coral shop owner who has tons of experience. We are going to take my 75g and convert into a sump. As far as the pump, we are going to drill the side of...

OK, the sump is partitioned and has cured for 24 hours. The plumbing is all done. The u tube eshopps overflow (300gph) is hung up. I puurposely drained the display about an inch below the teeth to play it safe. the mag 5 on the right side of my sump is in and ready to go and all return...
