Hey @Grover65k

Was reading that gg's require a salinity level of 1.002  is the billabong brackish or full fresh?

Just wondering if it could be a contributing factor to them not playing the  mummy, daddy game for you

Hi @billfish,

I don't think I have ever measured the salinity - just everything else !

The Billabong was a salt-water pool 5 years, but I expect it is fully freshwater at the moment.

I've seen  salinity pen meters "StarterPen Salinity meter - IC-ST10S" - do you know if they are any good?

never used one, salt water is too in depth for a simple bricklayer....well this one anyway, the only salt stuff i mess with is for baby brine shrimp

I'm not sure about the 1.002 salinity requirement but that's practically pure water (Specific gravity 1.000).

To measure salinity a simple hydrometer is all you need. Or step up to a refractometer (about $30) which can factor in temperature. Or dont be afraid to just taste the water for salt although TDS may be more useful than salinity.

How long does it take for the bottle to clear?

The billabong is essentially one large settlement tank so if you could keep the fish from stirring up the bottom or use a network of drain pipes to pick up the sludge directly off the bottom then your pool would clear quite nicely and hopefully quickly.

If you want some electronic wizardry then have a look at this instead - https://www.pondalgaesolutions.com/ultrasonicalgaecontrol.html

So...  How is the Billabong Going?

In a word... "Good"

Yes, it's still green, but the GPGs are visible for at least a metre down under.

The Cetus Sieve Thingie is doing a great job of removing crud from the depths.  

The Bog Bed Filter looks a little snowed under, or at least  the Big Blue Barrel filters probably need a clean as there is a layer of fine green sludge on top of the scoria. Out of the 10 water iris plants, 9 have thrived and 1 has keeled over. The Pandanus plants from @aquaholic99 are holding their own, but Grover is still waiting for Oxley Nursery to get a new supply so that he can try adapting them to soggy conditions. Also, he is thinking of reducing the duration of the flood cycle to make things a little bit dryer to let the plants establish.

The GPGs love their lettuce - Woolworth stores tend to leave the outer leaves on their lettuce, so you get more leaf for your $ than at Coles.  The Giant Gouramis also love hiding in the Elephant Ears where there are leaves/stems flat on the water and scaring Grover and the housemate with giant splashes when you least expect it.

Hopefully, new photos will be available on the weekend.

Cheers,

Grover

(was up-country last weekend, hence the overloaded BBB filters)

Friday Fotos...

Hmm...

Time to buy some new ducklings from Bunnings!

Grover keeps glimpsing this one and having heart palpitations that he's seeing a "floatie" GPG.

In reality, it's marking the top of the 2m deep sump pump for the Cetus Sieve.

And so that you know what a backyard tropical paradise looks like for GPGs -

But the stars of the show are these guys and ladies!!

Thoughts on a Giant Gourami...

We all start as very small ones.

But we have the potential to grow and mostly, God willing, we do.

Those trips to the aquarium store where we pressed our nose up against a tank full of fat, black mollies like black olives from some exotic european land.

Or else, the quicksilver Montezuma swordtails chasing females with dark half-crescent bellies.

Ahh...  the introduction to wild-caught Braziliensis - they of the startling electric blue sheen, and soon the hordes of babies swimming in a primary school and shepherded by caring parents.

Onwards and larger still, you were swayed by Oscars. Their personality, their in-your-face excitement, their sheer eye-rolling joy at chasing and catching wriggling worms!

 

And then?

The giant pink gourami swam into your life.

Tiddles, the first of a cohort of giants.

Is this a dagger GPG which I see before me...?

@aquaholic99 was Right!

The Bog Bed Filter, the Cetus Sieve Thingie, and the original pool pump just might be making inroads to clear the green water!

Photos from today (whilst leaning on the pool fence) . Grover counted 7 GPGs without even trying!

Hooray from the Billabong viewing sidelines.

Good news Grover65K!

Normally the water would be getting greener and darker with the longer day lengths and stronger intensity sun so it's most definitely improving. 

Wait to see if this improvement continues but I was also thinking you could boost the effectiveness of your UV by putting them in parallel with a much higher water flow.

The trick is to put the water through the UV system faster than the green water can reproduce in the pool so 30,000 LPH - 40,000 LPH during the day (solar panels).

Would be easy to plumb up your existing 4 UV filters similar to this link below.

https://www.alibaba.com/product-detail/Mariculture-Fish-Breeding-UV-Filter-for_60301616516.html

So high collective flow rate but individually low enough flow for effective kill cycle.

I will be building a 600 - 800 watt UV system similar for myself in the next few months to kill white spot (without chemicals).

I priced single unit UV systems and couldn't find one below AUD$10K so I will join 10 smaller (75 watt) units myself.

Thanx!

I have set up the 4 Blagdon UV filters as pair parallels  - best shown in my technical design drawing as detailed below.

So, I think this is helping.

I also think that I need to clean out the Big Blue Barrels at least fortnightly.  During Winter I was doing it monthly, but the sludge load has increased, and the Bog Bed Filter is looking rather sludgy on top.  The plants are starting to take hold (as well as some cherry tomato plants!).

Moonlighting at the Billabong

Grover went for an 11pm wander out with the torch to do GPG-spotting (also it's the start of Cane Toad season, so best to be prepared).

He saw 5 moderately large plecostomus sitting on the Billabong's side ledge (moderately large = 40cm+).

And counted 8 GPGs just drifting around happily.  Those cast-off lettuce leaves from Woolworths disappear alarmingly fast each morning!  Leading to happy GPGs.

 

Another reason they are so happy is that they think they are back in Bali, or S.E. Asia somewhere based on the water temperature !

The GPGs like their warmth :flame:

Cheers,

Grover

(he dabbled his toes in there to chop the Elephant Ears back and it felt like a warm bath!)

'Twas the week before Christmas...

Well... close enough!

:angel:  Merry Christmas to QLDAFers and all our readers  :amen:

 

And what's really been happening in the Billabong?

The Bog Bed Filter (BBF) is doing OK, except that the huge amount of sludge is coating the scoria, rather than letting it breathe. Possibly, this may be just a summer problem.  Grover temporarily closed off the outflow and rinsed the top layer of scoria, but the sludge has built up again.  Possibly he needs to up the cleaning regime of the Big Blue Barrels (which are acting as a primary filter before the BBF) to once a week, rather than once a month over Summer.

Sludge-050.thumb.jpg.5c0caec3b10d7a9af58550cdef9d70dc.jpg

 

In regard to current breeding behaviour of the GPGs - no sign of activity (nil, zip, nada).  Honestly, Grover needs to plan in advance for next year and have an above-ground pool already setup so that when the blue cover comes off the Billabong (around September and you see the fish again), he can catch a likely pair and add them straight to the A-G pool.  With the required floating vegetation, green water, lots of food, and Barry Manilow on continuous loop in underwater speakers. :drum:

And now to the Cetus Sieve.  It's not as "low maintenance" as Grover wishes.  As an experiment he let it run for a week, and the sheer volume of sludge was 'terrifying' to see.  It was causing some water to overflow and go down the drain rather than wash the sludge out.  Now it gets a quick hose out at the end of each day.  It may be because of the Elephant Ears and the GPGs that there is  SO MUCH  sludge.  Oh well... :frusty:   maybe he should keep neon tetras in the Billabong!

One thing the GPGs did enjoy lately was the bucketing rain we had in Brissie!  Excellent!  Water just pouring from the sky and freshening up the Billabong amazingly!

Thanx for sticking with Grover and the GPGs during the 2020 Covid year :deadhorse:

Looking forward to a much improved 2021 Year  :welcome:

Best Regards,

Grover

Back to the Bog Bed Filter...

You may have noticed a short break for the GPGs over the Christmas period.

Grover was otherwise occupied with farm activities at Kangaroo Creek south of Grafton.  Luckily, the police let him and The Dog back in at the COVID-19 Border Control near the  Cobaki Lakes M1 Pacific Motorway on approach to the Queensland Border!

During his absence the sump pump powering the Cetus Sieve swallowed a chunk of plastic from one of the previous Aquael pumps, and ground to a halt.  It has now burst back into life after the offending chunk was removed, but Grover has also shot off to his LFS (Bunnings) for a backup Ryobi Sump pump  - just in case!

Anyway,

The Bog Bed Filter looked very mucky, so the Big Blue Barrels have been cleaned.  Appearances may be deceptive, because the new water iris plants have doubled or tripled in size, and the 'Edible Pandan' (PS: it's never going in any salad that Grover's housemate may create - you can see below what it grows in!!!) has started to sprout and develop new shoots - Hooray :dance:   

Pandan-050.thumb.jpg.7292013947d8b256fe092d55ea1a12aa.jpg

 

And just to get in early...

Happy New Year for 2021 !      The 2020 year will soon be officially  :closed_2:

Bog Bed Filter Update:-

The iris plants are growing strongly, the giant amazon sword plants have taken hold (one even sending out a flower stalk), and the edible pandans are still hanging in there.  Mind you, I'm still waiting for Oxley Nursery to get some more in so I can attempt to adapt them to boggy, soggy conditions in the BBF.

Edible Pandans

Hooray! 

Oxley Nursery has received a supply of Edible Pandans (Pandanus amaryllifolius) so I ordered x6 and pick them up tomorrow!

Now I have to work out how to adapt them from normal pot plants into boggy, soggy BBF plants without killing them (@ $23 a plant).

Photos tomorrow :-)
