Backyard Aquaponics
A place to discuss aquaponics

Finally got ours sorted using this thread as the guide...





Brother in law gave me an old UPS the other day & am now thinking I might have a go at running the 12v full time & use the ups as a backup.. Will have to look into it a bit more yet...

Thanks for the thread & all the info guys...

Fantastic Rob.

As always, love your vids and updates.

I see the new fishies are quite active! I tell you what, they are so much more friendly than the ones I have owned over the years. Ive never owned a batch that beg at the water edge for a feed... quite remarkable.

Great work and great vid.

Well done Bob, I would suggest a couple more air stones.

Just on the back up or in general chainsaw?? I will be adding the 6 line fitting that came with the pump now I found it & the other 2 stones..




They never used to be that friendly Charlie, just lately since the water temp has come up.. Sort of worried that I am under feeding them.. Still feeding them the 2mm floating pellets & lettuce now..

Thanks guys..

I was just reading this thread and thought its being a while since I tested my backup system.

It didn't work.

I bought mine from Murray Hallam a couple of years ago so is well out of warranty.

I pulled it apart and found it was only a badly soldered joint.


But just for interest I thought I would take a photo of it and post it here.

what is used is a 12amp 250VAC relay.

It has the advantage that you don't need a 12 volt transformer as you just hook it upto the 240VAC

The disadvantage is that you have to work with 240 volts hence you need to know what you are doing.

Obviously, anything to do with 240 VAC needs to be checked by a qualified electrician before use.


cheers Lou

Thats fine Trout if your an Electrician (or know what your doing) But the whole point of this thread was for people to safely make their own backup without playing with 240V.

Yeah, only electricians should play with 240V.. That doesn't look like it's been built by an electrician either...

Or someone that knows how to solder properly

My recommendation is to not use a trickle charger, and use a 3 stage smart charger, with bulk, absorption, and FLOAT stages. The important stage is float, that is what does not kill batteries, as opposed to trickle.

I'm using a CTEX MXS 5 12V 5 amp as part of my back up system

Shameless self promotion:

G'day guys,

The pump that chainsaw supplied no longer has stock..tried calling...been trying to call all day..no response.

Anyhow, how this alternative on ebay

However it can only do 38LPM, would this be sufficient for my 1000lt IBC?


Thank you in advance!

Cheers

Can someone post some links to parts? So I can just click n buy the whole setup

Is this the relay?

Have a look at page 1 first post then read on, you can also check through my thread for a photo of what I used for my backup page 4 or 5 I think. Cheers

Ive had a couple of requests and will be making some for others prebuilt and tested
