Did you put this one back into the river after taking pic? Or did you just want a pic with the habitat in the back?

Citroen CX Break

I only put the UV on for a day or two once a month. leaving it on constantly can get expensive. Certainly Both in your energy bill but also, these lamps don't last very long. After ~5000 hours (read the manual) most of them need to be replaced - and they are costly. + putting them one and out count...

Look`s like tubifex or something in that direction to me. What would be indeed a sign for bad water / overfeeding. Well fish will eat them sooner or later.

The mouth points in the Hopliancistrus direction.

Look here http://www.planetcatfish.com/books it`s already on planetcatfish.

Hi all, ... Times change for the mother of the nation Sturi. Look at the pros, it's St. Aureum or St. Panamese? Length without flag TL 16cm, 6.29 " . St. aureum for me is the belly, the bottom too bright ... Greetings Ralf Or Sturisoma festivum, what I rather think. Open a new thread in the ID...

Really no dorsal now better, clearer I see
Parailia I now think
Look`s more like a Schilbeidae then like a Siluridae / Kryptopterus to me

The "Confused" in the topic name fit´s really well
Let`s wait for the others what they say

I would rather say Pareutropius buffei , or nearby species. Err, Pareutropius buffei has a dorsal fin! Jools We might just don`t see it in the pics? The wiskers of Kryptopterus, as well as those of Ompok, go frontwards,those of Pareutropius go towards tail. Or ar there no whiskers at all an we look...

I would rather say , or nearby species.

Question:
Why don`t you put the new tanks on the same wall as the big one, would give you one more 60*80 instead of a 60*60 and a bit more place for working

Btw: Very interesting As such topics allways are

What is the white something (3:00) in the left corner of the tank
A UV-steriliser

3. Anaerobic bacteria - this should not normally happen in an aquarium, but I remember reading about someone who pumped water ,very slowly, through a long pipe and managed to reduce the nitrate content that way. This methode and simulare are not save without measuering Red/Ox at the output of the p...

There`s a new tv canal for people like us: http://www.aquanet.tv/ Well, - it is not specific for catfish :( - it is (at the moment?) only in German :? - it is not allways visible, it has fixed showing times :( - the films come with disturbance (at least to me) :oops: But, you get fishy tv :wink: :wi...

Well, we should speak about conductivity instead of TDS. :-X Back to topic - we still have Jools Oyster Sheels as softest = best methode for the normal aquarist (for example AndrewC)to use inside the tank - then I would say the next stronger methode would be supplying little ammount of NaHCO3 to tap...

Are you sure hydroxides and hydronium contribute towards conductivity? Sure, I saw it at different experiments. The one you sould try after that from Bas Pels is to take 150ml RO water and put 20ml 0,1M HCl and your TDS meter in, then you supply succrssive 1ml 0,1M NaOH till you have 40ml 0,1M NaOH...

to check if the ro unit is clearing all the phosphate out of the my tap water. From a chemist's point of view, I wonder what might be yout tds - I mean, I know it is total dissolved solids, but I wonder what is dissolved. I don't expect any phosphate in this water, if any is in it, your RO unit wou...

Normaly steel and other metals get parkerized/ phosphated/ phosphatized befor coated with organic materials for better liability So I would suggest you first grind it a bit then put it with only the part which you want to silicon for 5-10min in a mix of cola and water (try to get 0,3-1 Vol% Phosphor...

agree

I do have, however a redox measuring device. This apparatus can be held with its sensitive parts submerged in the tank, and it tells me about the equilibrium between oxidising matter (such as oxygen) and oxygen consuming matter (such as organic waste) :? Redox measuring devices don`t measur oxygen ...

So in other words,both 2 and 3(for the one is obvious :lol: ) are fake or is 3 more accurate? Not fake, it´s made by putting two conected metals into the tank, so it isn`t there normally As i have said in a previous post of mine,i have removed the grounds from both of my tank :wink: didn`t notice t...

Is what the voltmeter measures when placed in the tank always completely ''fake''(when you have the equipment running i mean,not without the equipment) or does it also shows some voltage that does exist and after taking it off the tank? 1. If you put only one cable from the voltmeter to your tank -...

Doesn`t matter. The voltmeter shows someting, as sayed, becouse you put metal in

Anyone likes to translat this, about Aspidoras, as I have no idear what some of english words for the german`s are:

Thank you very much for your reply :D So the volts shown dont exist and are a ''bug'' of the voltmeter or do they actually exist but are only seen through difference in voltage between the tank and a neutral object? The voltage is definitely there - but only because you actually have the metal in t...

Durlänger, Thank you very much for your reply :wink: It was very enlightening on this subject :) So,in other words,the volts shown by the voltmeter in the aquarium actually dont exist but are created by the metal contact of the voltmeter? Nearly it`s created by the metal alone, the voltmeter we use...

The few volts on your voltmeter don`t come from electromagnetic fields, those are created by your metal contact as you then great a "Metal-/metalion-electrode" :!: If you take another metal for contact with your water, you will see that your voltmeter shows a other number :) That`s somethi...
