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.
Fantastic tank, and nice to see another German on this site - even if I am living in Ohio now
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...
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 250â‚¬ (about 300$, i guess). I can send you a link to the store if you want to.
