I have a question for you guys. Will a pH of 8 be detrimental to black arowana fin recovery? I 've have a black arowana with split up fins and its been 3 plus weeks and they have not healed. I am going to add drift wood to lower the pH is this a good ideal, and how much could it lower my pH? The arowana is eating and healthy except for its split up fins. I do 40-50 percent water changes once a week, my nitrites are zero and my nitrates are under 20ppm. The black arowana is around 4 inches long and growing out in a 10 gallon tank. The temperature of the water is around 80 degrees.

Thanks in advance for any advise.
 
6.4 t0 7.0 is optimal pH for black aros, but really your main goal with practically any fish is to achieve and keep a neutral pH level, but there are exceptions for this matter such as Discus for example actually prefer their water on the real acidic side.
 
change the water to lower the pH and add the driftwood if u like

so what if you your tap water is already @ 8. ph.
only way is through R/O, Peat moss, and driftwood.?
 
More important that a specific pH is a stable pH. 8.0 is fine for an aro as long as its consistent, do not use pH altering chemicals these are very dangerous a can back fire very easy.......Keep the pH the same as your tap water. Your problem is most likely something else with water quality, diet, and environment. What is the full run down from your water tests? Tank mates? Water conditioner? Stress?

Nitrate: < 20 ppm
Nitrite: 0 ppm
Hardness: 120 ppm
Alkalinity/Buffering Capacity: 120 ppm
pH: 8

The only tank mates at the moment ate snails. They are only eating freeze dried blood worms. I do a wc once a wk and I add prime and aquarium salt accordingly.

I'm not sure how stressed they are I have 2 in 2 separate 10 gallon tanks to grow out. They are eating well and active. I have HOB filters on both tanks. Could the water flow created by the HOB's be preventing the fins from healing? Baby blacks seem real fragile

Thanks for the replys:thumbsup:

Looks good. Whats the temp? As for the water flow...as long as they swim around with out getting pushed by current. Sometimes fins can take awhile to heal but if there is no healing in 3 weeks....raises some concerns. Maybe a couple pics would help.

Best of luck!

The temperature is 82-83 degrees F, and they do get pushed by the water flow at times when they go after food. I will add some pictures of them tomorrow. I have noticed a little healing but not as much as I am used to seeing with my other fish species. I guess arowanas just heal alot slower.
 
The fist one is of the smaller black its less chipped up and the second is of the larger black he is more chipped up. I think maybe the yoyo loaches could have done this? However they were removed 2-3 weeks ago. I have only noticed minimal healing. :shakehead:shakehead:shakehead
