Hi all,
FWIW, this Hanna model in its default factory settings (which is what I use) calculates TDS as 1/2 conductivity. So if my TDS is 30ppm, the conductivity is 60ppm. If I wanted, I could change the instrument to calculate TDS as 2/3 conductivity, but as you say it's just a math equation and if ...

Hi all,
Hi all,
...... This of course is my 4-foot-long aquarium with the waterfall at one end, almost laminar flow (okay, let's just say unidirectional flow) across the length of the tank into a Matten filter at the other end, and the (semi)-floating kinon/raft of plants, Manzanita twigs, and ...

Hi all,

Initial estimate of eggs, counting only the most superficial layers of eggs in the two big egg masses, is 903 eggs! Certainly there's over 100 uncounted eggs remaining deep in the two parts of the main egg mass. Do you think there is anything special about this tank? It is obviously ...

Hi all,
You can use a very dilute solution of fenbendazole to kill Hydra.

It will also kill Tricladida flatworms, but only at higher concentrations.

Hi all,

lower water current (these fish had a significant strong water current provided by a wavemaker... I thought they liked it because typically I'd find two fish in the current every day; the other fish would be on a floating wood log near the water current or on the Matten filter away from ...

Hi all,

Nice, have a look at <" Lamontichthys llanero tank setup? ">.

Hi all,

Thanks for the update, I've always "felt" there was something in this It is still a really interesting area.

Reading between the lines, I think they feel that ammonia (NH3) and nitrite (NO2-) are an answered question, but they are particularly interested in a microbial "answer" to ...

Hi all,

I'm using green onions (scallions), Allium fistulosum . I don't know them well enough to know if they should fare any better than regular yellow onions in this setting, but there are videos and websites that describe growing them in aquaponics. They should have more chance of success ...

Hi all,

Ever since one of my earliest posts ( Using deep gravel and bacteria to control nitrogen ), I've always appreciated your input and experience. Thanks for chiming in.

It is still an interesting thread.

Hi all,

While my green onions didn't work (I tried twice but could try again), I might try the green onions again too - My thought there was that I should start them under better conditions then transplant them to the spillway, rather than just shoving the bulbs into the spillway;
I'm not sure ...

Hi all,
That is looking very promising.

I like the Ginger. Another culinary item you could try would be Lemon Grass ( Cymbopogon citratus ). It will grow from the stems you buy in the supermarket etc. (as long as they have a small amount of rhizome left at the leaf base).

If its OK? I'll post a ...

Sorry Ed*,
@bekateen is Eric

Larry was a great man. Hopefully the more holistic, ecological approach to aquarium keeping, that he was an early proponent of, will eventually gain greater traction.

He was certainly an important figure in my own personal journey.

Cheers Darrel

Hi all,
*Ed, thank you for your words.

I was really sorry to hear of Larry's demise.

I also never met him in person, but we talked over a long time period, and the World, and PC, are a much poorer place without him.

Yes it is fine. I gave some hollow logs to a friend, and they were used, even when they were still floating.

Hi all,
:)) They did exceedingly well in my Marineland HOB in the greenhouse tank, to the point that their roots grew out over the spillway of the HOB into the tank. Not only that, they had started forming strobili!

I'm hoping their roots will help provide the complexity to the kinon over time so ...

Hi all,
Also, today I added horsetails to the kinon. Horsetails did really well in my greenhouse tank; let see how they do in an indoor tank by the window. I might be careful for what you wish for, in my experience they tend to do a bit to well.

To give a catfish related analogy it is a bit like ...

Hi all, That said, I'd also make a counterpoint to the criticality of pH. As Darrel has pointed out multiple times (I think) in older threads (@dw1305, please correct me if I'm wrong on this attribution), since pH is a calculation based on ratios of acids and bases, the pH becomes less critical as ...

Hi all,
I'm sorry for your loss, it is horrible when a fish dies. I'll add in @bekateen , <" he keeps these ">.

Could we have a picture of the aquarium? Often the ...

Hi all,

But I wonder, isn’t the sucker-mouth an adaptation to fast flowing water? Fast flowing water is usually clear and just about the opposite of black-water.

Maybe not blackwater as such, but I think fast flowing water can be tannin stained, you could have a situation where a "black-water ...

Hi all,
Perpetually soft, acidic water is a great advantage, because it is much, much easier to add compounds to water, rather then take them away.
I can't see the TDS effecting much more then hinting to a seasonal change. How frequently did you water change before?
There are some potential ...

Hi all,

In my experience, 9/10 one species will be more thriving and gregarious and exploit access to food and preferable structure and caves while the other species doesn't thrive.

Thank you Darrel for this. IDK if my memory is failing but I clearly remember your numerous great and helpful posts on the NO3- tests and yet I don't recall your beef with the API test tube TAN tests (and the likes). Could you link your writeup / post(s) on the TAN, please, if you had one ...

Hi all,

Just did water quality texts. Ph8, ammonia 0-0.25ppm, nitrite 0ppm, Nitrate 40ppm. I have recently been adding a potassium supplement to help my plants in there along with aquarium co-op easy green about once a week. Don't put too much reliance on the test kit results, both TAN ammonia ...
