Just have a quick question. Would a 3500lph pump provide sufficient oxygen in a single IBC system or would I be better off getting an air pump also?

Actually, one more question. Thinking about backup, I was leaning towards a UPS+deep cycle battery, mainly because I've got more experience with using UPS's and I like the auto switch over, etc (no idea how to set that up with a solar backup system). Would that be sufficient to run the two pumps through or should I just have an air pump as backup?

Thanks in advance.

With any luck I'll get some holes dug with the auger today to see where I stand with tree roots. That is if I can summon the energy, I feel like going to bed, lol.

The water pump alone will be fine if you dont go overboard with your stocking density. The water returning from the GB will provide sufficient aeration and water turn over.

I use a UPS for back up, I run 2 water pumps and an aerator and I find it a great little set up that is hassle free. Plug it in and charge it right up then turn off the power supply and record how long it runs your system for, then you can decide if your happy with that duration or not. If not (I wasnt), you can open up the UPS and replace the small batteries with a couple of large deep cycle batteries and it will give you a longer run time. You will require someone with electrical knowledge to do this safely.

That's good to know, I thought it'd be ok given I am going to stock modestly. Good to have confirmation.

Good to know you've had long term success with yours, I was hoping it'd be a simple way to set up my backup system using things I'm already familiar with.

The UPS I'll most likely use probably won't provide long enough backup time, but I really don't know how it'd run with a substantially lower power draw than a PC, so a good test would be in order. Chances are I'll want to hook up a deep cycle battery though. I should be able to do it myself, I've done some electrical stuff before. I just have to make sure I've got my head around it fully so I don't end up frying myself, lol.

Thanks for the response and help, mucho appreciado! :D

Started the hole digging today and I'm happy I'm not trying to grow stuff in the soil, it's rock hard and so dry, lol. Glad I have my personal mole machine too, it has helped loosen things up a bit, but I've got a long way to go and need a pick.

Once again it's interesting seeing all of the rubble that comes out of the ground, this spot there is less old brick and more glass/pottery, I think the brick vein was on the other side of the block, lol.

Now, to have a shower, I've got to get rid of this dirt tan!

You call it a dirt tan, I call it a protective layer...

Just a little update, not much progress as I've been down at Wilsons Prom for the last week. The hole has gotten a little deeper, close to the depth I want it, but I'll probably cheat and build up the outside a bit too once the FT's are in. I had a bit of help from a friend to dig and carry dirt, and from filling the hole with water and letting it soak in. Why I didn't do that from the start I don't know, lol.

It's always frustrating when you finish something and then discover a much easier way to do something! :D

Lol, it's always the way. :D I will have to do the same when I'm digging the post holes for the front fence, it should make it a piece of cake.

It does make the wheelbarrow a lot heavier when carting the dirt though, lol. :lol:

Just had a quick question before I stick the tanks in the hole, should I insulate around/underneath the part that will be buried?

I'll put some around the parts above ground, and I'll be using a bit of tin as a barrier between dirt and tank to help support it, but is it useful or counter-productive to actually insulate the tank that is buried?

Thanks!

That is up to you. If you insulate the tanks will not be ground coupled. Ground coupling may or may not be a good thing for you.

I think it would be ok to not insulate them, we don't tend to get extreme cold during winter so no real risk of water freezing that I can see.

What are the sort of scenarios where ground coupling the tanks isn't really ideal?

Thanks for the response. :)

Hopefully I can motivate myself to cut the tanks and get them in today, once I've tackled Mount Foldmore that is!

Mount Foldmore... I have one of those. I only scale it when I have to...

I managed to get one IBC cut up and cleaned with the help of a friend. The cleaning took longer than the cutting lol, the sweetener (I'm assuming glucose) was a pain to get off the bottom but nothing a whole lot of hot water didn't fix. :wink:

The cage was plonked in the hole and GB frame stuck on top. Height wise it's perfect for me, I think I'll be happy working with it once it's finished. I've just got to get it finished!
