View Full Version : Will it work for me: external pump?

I am considering the purchase of the Renew and Storm package but need some design help.

You can see my current design below. My question is: how do I get away from have internal pumps? I plan on having a Iwaki pump on the bottom Saltwater container, but don't see how this system will fit into this design. Could you please help.

Hi Brian,

Thanks for the great sketch. They are always helpful.

You can certainly use the Iwaki external pump on your saltwater mixing bin. Simply install a flow control valve on the output of the pump to limit its flow from between 1gpm and 2 gpm so that the Metering Reservoir fills in about 45 seconds to one minute or so.

A submersible or external pump can be installed in/on your sump to move water to the waste water Metering Reservoir as well.

Regarding the RODI bin sitting higher than your sump and other tanks, if you intend to top off directly from this bin you will need to install an anti-siphon valve at a level higher than the top of the RODI bin to prevent a forward siphon from forming. We sell those in our Accessories section.

Please let me know if you have any questions at all.

Best regards,
Kevin

So if I understand correctly:

The Iwaki will be plug into the Renew system, and have a flow control valve on the output side. When the Renew Reservoir needs water, it will kick on the pump filling the reservoir. In regards to the waste, flow control valve will be attached to the main manifold and pump to the waste Reservoir. Correct? I worry about the pump kicking on and off.

In regards to the Storm ATO system. With the RO tank being elevated do I even need a pump, or just a check valve and gravity?

Correct. When it is time for the RENEW™ to perform a 1 gallon exchange, the control module will turn your Iwaki on until the Metering Reservoir is full, then shut it off. I should have initially pointed out the the Iwaki should pull less than 2.5 amps. It probably does, but you should check to be sure.

In regards to the waste, flow control valve will be attached to the main manifold and pump to the waste Reservoir. Correct? I worry about the pump kicking on and off.

From this I believe you intend to not use a pump to move water from your sump into the waste Metering Reservoir, and instead intend to use an electrically operated valve to allow water to flow into the Metering Reservoir, using your existing pump. While you may be able to do this, we don't offer such a valve. If you do have this valve, please make sure it draws 2.5 amps or less, and that the flow rate is between 1gpm and 2gpm.

In regards to the Storm ATO system. With the RO tank being elevated do I even need a pump, or just a check valve and gravity?

Certainly you could use a float valve to accomplish this, but keep in mind there could be a major problem if the mechanical float valve fails. Additionally, every time the RENEW™ removes a gallon of water for a water change, the water level will drop and the fresh water will be allowed to flow into your sump. The end result it that you will have too much water introduced into your sump, and it will lower your salinity some. I would recommend using the STORM™ with a pump and anti-siphon kit - it adds a whole lot of redundancy and communicates with the RENEW™ so that no fresh water is added when the RENEW™ is in an active exchange cycle.

TO ANYONE READING JUST THIS POST: THIS IS A MODIFIED SETUP. NOT THAT RECOMMENDED BY GENESIS!


So here is my design with the Renew and Storm system. Please let me know if you see any problem with the setup. I am looking forward to having this system as a part of my reefing experience.

The electronic valve that I am suggesting between the waste water of the Renew and the ATO of the storm can be seen at the link below. It is a simple irrigation in-line valve that is rate at .2-22 gpm. This flow will be controlled with a gate valve before the irrigation in-line valve. The solenoid is powered by a 24 VAC power supply that will be plugged into the Genesis Control boxes. The drain will be hooked up to a drainage line.

So what do you think? Any problem with my though process?

This photo may be confusing, but it is the complete setup Storm and Renew

Thos irrigation valves are low voltage. 110v comes out of the storm. can you get 110v valves? Also will they work with salt water?

I suppose you could us a a transformer. Most of the irr.valves are 24 volt. I might have a valve here. I'll take it apart and see if there are any metal parts inside. I curious to find out myself.

That would be great. I planned on using a 24 VAC transformer as the power supply. But I did worry about the exposure to saltwater.

Hi guys,

This setup should work just fine! As you're both aware, just make sure that the valve is compatible with salt water, and that it doesn't draw more than 2.5A when energized. Naturally you'll need to use the transformer to step the 110VAC down to 24VAC or 24VDC, depending on the valve.

I have taken a look at numerous valves of this sort and most do have a metal spring inside that will corrode with extended exposure to salt water. If you can replace that spring with high grade SS, you should be alright.

Have a great day,
Kevin

by the way ur pic of renew system shows drain on the saltwater metering bucket.thats not true. there is a feed from saltwater bin second if overflow back to saltwater bin (not drain) then third to sump. the only drain is on the metering bucket that collects water from sump.

Yep, bnumair's right. I didn't catch that. Thanks, bnumair!

It could technically be set up as sketched, but there would be a small amount of wasted new saltwater if the overflow is sent the drain. The loopback tube that is currently shown going from the replacement Metering Reservoir to the drain is used to help ensure exactly one gallon of water is measured out, and in order to prevent the "extra" water from going straight to the drain it is generally routed back to the mixing bin.

Thanks again for catching that, bnumair!

Thanks so much for the catch. I can easily have this run into a small collection container, or maybe back into the barrel. I want to keep the barrel as closed as possable, so I will be limitling the number of hole cut into in.

Again thanks bnumair, NH Fish, and kevin for all the help with this design.
