I don't really know why the hole occurred. There's a crease in the liner and the slit occurred on the crease.  I'm wondering if the tension on the liner by a full tank of water caused it to fail.   There are a couple of other spots where the fold in the liner appears to be fraying too, but they're genuine liner folds and not really a concern. 

I'm a bit puzzled to be honest.

The patch is a self-adhesive one from the same manufacturer as the liner.  It was quite thick, so I'm hoping it'll provide a level of support for that part of the liner.

Time will tell.

What caused the slit?  It looks like there was a fold in the liner there.

Well THERE'S your problem!

I finally admitted to myself that I had a leak in my fish tank.  I've been in denial for weeks.   So I let the tank slowly leak dry, this being the recommended method to determine at what level the leak is at.   Well, the tank emptied all the way out.  That must mean that I have a leak in the bottom.  Oh great!   

I snagged the fish and temporarily housed them in the DWC bed, which isn't leaking a drop.  They didn't seem to mind too much.

Since the tank was empty, I took the time to brush it out and remove all the debris that has fallen in there over the last 2.5 years.

Slapped a patch on the hole, which was remarkably obvious, and I'll find out tomorrow how well it holds.

A slit big enough to put a couple of fingers through

Yup!  That'll let out the water.

Patch applied and silicone smeared

John, if u can't find anything else local i can double check. i have about 15 fish in the garage.  i'd have to count and measure.  some of them haven't grown very much (females i suppose) and some are twice their size.

Is there anyone in Phoenix that has tilapia fingerlings for sale?
I am looking for 30 to stock my AP system.

Thanks, Kim. I might actually be getting rid of the entire thing myself. However, there are a number of Koi and a  few large fancy goldfish that I dearly love, so am thinking I need to buy a 55-75 gallon tank for inside the house, and then just get a grow light, We have a pool, and so the room for the thing isn't there, either, and I just hate worrying about the cold water, and then too much sun/heat, and then having to put ice in the water when it gets really hot. I think if I had a larger yard area, where I could build a greenhouse area, it might work, but I have just strips of ground around a huge pool that takes up darned near the whole yard, and the tank right now is taking up too much space under our back awning. I just hate to give up - I spend so much $$ on everything....

Arlene, I bought my IBC set-up off of craigslist, live with fish and plants.  getting it home and hooked up was no joke.  took all night.  without Jim Troyer's help we would've killed the fish and would've taken longer cuz we didn't know what we were doing.  we jumped into AP pretty fast.  if u're going to be frustrated each winter it's probably worth moving it.  we were moving it from another town, so it was more involved.  u'll need some clean empty trash cans or something to hold water in to save bacteria.  wintertime would be a good time to do it i'd think since u don't have a lot plants to kill now anyway and fish could probably handle the transition better, i'd think.  this may be a good opportunity for u to bury the AP.  we are debating selling our system or moving it as we're putting in a pool and it's in the way of that.  if we move it we'll bury the tank and possibly have the gardenbeds ground level.  i'll be talking with Jim about that!

all the best.  it's no fun but how disappointing each winter to not be able to grow anything!

as for the pesticide, i've heard to be careful with oils.  i ended u deciding to risk it and got some neem oil, too, but haven't applied it, yet.  i'd really be careful with essential oils, i'd think, though. especially peppermint.  have u ever gotten that in your eyes?  oww!  :)

This is posted on instructible as an organic pesticide. Would these ingredients be safe to use on plants in the growbed?

Ingredients:

  • 1/4 gallon (4 cups) warm water
  • 1/4 tablespoon neem oil
  • 1/2 teaspoon 7.8% potassium silicate solution
  • 1/4 oz (1.5 teaspoons or 150 drops total) assorted essential oils - we're using an even blend of ginger, rosemary, clove, peppermint and eucalyptus
  • 1 tablespoon aloe vera juice (we have a powder we add to water to make this)

@Arlene - I can relate - my garden is at the north side of my home right now as well.  Most things did grow, but not a lot grew well (Thai Basil, Green Onions, and Jim's Water Iris seem to be the winners, everything else is stunted with the winter shade and summer sun exposure).  Didn't get to moving it yet, but that's because I'm putting it off knowing I need to redo my piping.

When I do get to it, I'll transfer the fish to the new tank and empty out the sump (current FT) to get it out of the ground.  I've had the FT in the ground with my current set up, and more than once the water volume got lower than I or probably the fish were comfortable with.

@John - Have you tried gammarus in your DWC?  I've read that they're almost like worms in a media bed when it comes to DWC, and they do wonders keeping it clean and taking care of sludge and root rot.
