Now that you've had it running for a while, do you feel it's as efficient as you originally hoped? Have you tracked how much water is moved each time the pump turns on to heat the tank? It looked like in your first video, that the "heater" was turning on every 30 minutes or so, and would stay on for 10 minutes at a time. Not too bad. That does make me think that legionella isn't really a concern because the lines are being flushed every 30 minutes, which is way more often than most hot water taps in a house. So it seems that legionella would be even less of a concern with a hot water heating system, even if it was just done using coiled pex in a sump. Does that sound right? Or am I missing something? Also, you mentioned in your first video, that with this system you could heat your tanks even during a power outage, but I don't understand how that would be the case if the system requires the pump to make it work. Any clarity you have to offer, is greatly appreciated! Thanks for being so willing to share your knowledge!

I bought the heat exchanger. I have a 250 gallon system and going to give it a go. I’m a plumber so the piping should be easy. I’m going to use a circular pump with a mixing valve off the boiler to be able to adjust my feed temp. To turn the pumps on I’m going to use my INKBIRD controller off a rib relay. Most of those grundfos circulators have built in check Valves. And no need for a zone valve if that circulator is only controller 1 zone ie. aquarium

How is that heat exchanger holding up. My only concern is it getting a pin hole and leaking boiler water into my aquarium

You are a legend i live in a rented apartment and wanted to connect my frag tank up to my apex without having giant holes in the walls where i had to fit the usb ends through. Now I can just have 2 small holes for a wire. Thank you

Link for that model of battery?

Do you leave the stir running all the time or just some of the time ?

If you use the coax to BNC plug, can't you plug it directly in a pH or ORP port? Saving the need of the ASM module?

DUDE! Long term exposure to copper kills living things! If you have copper pipes in your house, you're probably ok, if you don't use copper fittings in your sump system. Some fish are okay with copper exposure (many fresh water fish are ok... kinda). Some marine (salt water) fish (the more expensive ones) will be killed by exposure to copper. Inverts will be killed by copper. I'd LOVE to do this for my 500 gal Reef and 900 gal FOWLR (angel fish) tank. But there'd have to be a no-copper solution. Once copper gets into your tank... pretty d**n hard to get it out.

Super helpful. The deep cycle battery is enough to run my entire 20g nano for a week. Lol thanks!

Great video. Why is your PVC so large?

Nice! You should post an Amazon affiliate link for the replacement battery.

Can someone get us a count on how many times he says "uh"????

Putting together a tank from equipment packed away 9 years ago. Per your video replaced batteries on two backups and worked great. Drilling out slowly made for more bite. Little alignment needed with pliers on the internal sheet metal parts. Many thanks for posting.

can you please make a short video while the feeder start to work? I am queries how is food at that time of feeding regarding to icy form

Nice Job, how about sending food directly to tank, can dosing pump handle it?

you should manufacture them

Very informative, thanks for the upload!

Ok so a few quick questions. 1. I plug the UPS in like normal after? 2. How do I regulate charging? 3. How do I power the wavemaker? Directly off the UPS instead of its power adapter?

Is there any formula that you use on how much vitamin C to add to your food?

any thoughts about using peltier systems to cool down food for preservation or using some of those small desktop fridges?

Awesome, thank you

Can you pls send a link for the diy venturi you got?

if anyone watches this add a FUSE as close as possible to the + on the battery, the reason why it was sparking when testing is because it was been earthed out and wasn't fused, so it will burn your house down if not fused when it fails.

OCD triggered

I made this! But for whatever reason I made it with UTP and not STP. I was really tired when I made it and ran it. Everything is working fine. 75 feed total run. It’s for my DOS water change system.

This video is pretty old, but I was wondering if you have experimented or have any info regarding trying to keep your tank at 81 so about 3 degrees higher than you keep yours?

This video is quite old now but I was thinking what about beer line pumps because they are calibrated to pump the exact amount each and every time they can be set at I pint or I litre. They are built to a food standard and built to run constantly. And you can pick them up for around $25 each.

sorry the guy lied to you :(

Is the thickness of the shield terminal connector thin enough where two can be plugged side by side into the Apex?

Do you know the link to replace this kind of battery? Great vid. Thanks...

The m40 needs a 24v, how are you able to use One 12v car battery?

Cant find reagents anywhere. Wtf. Spent all this money now what

On the light duty 110 cord.... since their wires are both black, when connecting to the relay wires, can they be interchanged? How do I know which one is live and neutral?

I love this video so much. Thanks for putting it out

That’s exactly what I need for my heater

on reef2reef there's a 3d printed part yuou can buy that'll use almost 100% of the reagent

Great tutorial and will be building one for myself soon. If anyone is like me and was hoping for a little more information on this relay, I was able to find it here, www.functionaldevices.com/support/downloads/datasheet-generator/?SKU=RIB2401B

Super cool video, I am about to build one myself but was having trouble finding the terminal connecter size. Not used to wiring electronics. Thanks.

Hey great video, very inspiring! I’m about to use for this project a mini mini fridge -the temperature inside the fridge is only between 8-10 Celsius do you think that can work? I’m planning to use mix of salt water with different cubes and change it every week

You just saved me $150 on replacing my dead battery backup! You are the man! I’d love to see your tank

Very cool, reccomend using 2 different color wires would be helpful for those doing it at home.

That’s great idea going to try this in the basement filter room thank for the video and the the one for the battery back up to

Amazing video man!

Thank you

I think Eco Tech must have seen your video and decided to get some profit out of people building their own battery backups because they have jacked the cable price and shipping to $5 ea and $12 shipping.

When you drill out screws and rivets put some pressure and drill slow instead of higher speeds. You actually eat up the metal quicker that way. Thanks for the great video. If I can't find an old ecotech backup battery cheap that I can replace the battery on then I will just build one like you did in your other video.

Great video. You could use a mixing valve to reduce the heat exchanger temp so it doesn't heat as fast. Not an issue for you but someone who doesn't have an apex might find it useful.

Well explained new subscriber Barry Manchester England 👍

Is that a DIY filter roller and is set up to your apex to rotate automatically or do you have to turn it manually?
