hi, all ray experts, i want to buy a motoro stingray and want to know what will affect the ray more than the other
i have a ph of 6.0 and ammonia level of 4.0, i know it is high but i try to keep it low
thank you for your time and responses
 
please be joking a ray wont last a day in 4 ammona it should be zero what size tank do you have whats in it what kind of filter do you have and how old is it btw a ph of 6 is fine
 
Ok I've clean up this thread. If it continues, the ban hammer is coming out and I swing hard.

To answer the actual question, high ammonia is worse. 4 is high. More details about your tank would help. It sounds like a new tank that can't handle the biological load of the rays. I've seen rays in 1.5 without showing ill effects, but it needs to be much closer to zero long term. If not, you need to look at more filtration to pull waste out before it breaks down.


Ammonia is less toxic at low pH. Most people don't fully understand the relationship between the two and the impact it has on the ability of the rays gills to function when exposed to them.


I suggest getting your water quality in check before buying the ray.
 
That pH is fine. The ammonia is toxic, especially to rays. That's what you should focus on.
 
A varying pH will affect the ray a LOT more than either high or low pH. Maintain what you have, after you get your tank fully cycled. As Zoodiver suggested, you probably don't have enough biomedia to support your stock, or perhaps your tank isn't big enough either thus filtration not enough anyway.

Motoros need a large tank footprint when they get older, And I think at least a 6x3 for a while will do fine (can grow out pups in a little bit smaller than this but will need an upgrade soon) to start and then upgrade the 3 to 4 foot wide when they get closer to mature size.
 
Many people may argue that pH would affect ammonia's toxicity.
While this is true as low pH means more ammonium [non toxic], IMO why risk it?
Make sure that your tank is fully cycled, that means ZERO in both ammonia and ammonium.
Then you don't have to care about the ph-ammonia toxicity relationship since it will always be non-toxic.
