What are those black ones?
Ahh. I haven't seen Trewavasae that dark.
Great looking tank! What types of Petros do you have in there? I cant recognize one or two of them. :)
[email protected] and thx for your praises.

These fish are in the tank:

9 Petrochromis Macrognathus Rainbow
20 Petrochromis Trewavasae
8 Petrochromis orthognathus Tricolor
5 Petrochromis Texas Kipili
4 Petrochromis Famula Texas Gold

The Petrochromis Texas Kipili are new today and will be raised for 5 fish. So until now I don't have any pix but they will follow. The 4 Petrochromis Famula Texas Gold will come to friend of mine because he has even 4 of them. In the near future I'll creat a new tank with 250x90x50.

Until now the petros are stressless, and hope so for the future.

ahh it was the Tricolors I couldnt recognize. Very nice. Again your tank is great.
Fantastic tank, and nice to see another German on this site - even if I am living in Ohio now :D

Apart from the awesome fish, I particularly like the aluminum canopy on the tank, which you say has been glued onto the tank? That sounds quite unusual! Did you built it yourself or is it store bought?

Another detail I find interesting is the "10L nitrate and phosphate column" through which you say you pump 1.5 times your tank volume per day. I guess it filters out nitrate and phosphate? How effective is it, and is it worth having since you still do 50% water changes weekly. I'd be interested in any details, like what's the column material, how often does it need to be replaced/recharged, how expensive is it...

Just curious :)

Hi Frank and thanks for your complements :D !

I bought the aluminium canopy in a shop of a friend of mine and built it then myself at home. It works, but it's quite different :thumb: .

The 10L column is very effective. It neither reduces the nitrate and phosphate loads in the water, it even reduces the bacterial loads. I have to feed a lot but even though the water is crystal clear. Before I installed the column this was not the case! The column runs about 5 up to 10 years and has to be regenerated with salt (NaCl) in every 2 up to 3 month. the nitrate and phosphate is now under 5mg/l . The coulmn costs about 250€ (about 300$, i guess). I can send you a link to the store if you want to.

Love the layout of the tank!!!! Is it a background or actual large rocks?
Actually both ^^ It's a combination of river peddle and moduls and a slimline background from "back to nature".
Markus - please check your PM. I would love to find out more about that column.
Hi Frank,
sorry, I was busy this days.
I looked for the link and just answerd you today.
