SHOULD I BE CONCERNED?!?

  • We are currently upgrading MFK. thanks! -neo
If you look at the end of my last thread i was told that my ray almost definitely died from a low PH.

I am not familiar with your thread, sorry. I was responding to the comment regarding pH and ammonia. I would find it hard to believe a ray was lost due to low pH, the natural habitat of most FW rays is very soft/acidic generally speaking.
 
Good to hear the ray is doing good now :) just an fyi its fluctuating ph that kills rays not low. My ph here in Vancouver is barley 6.5. If you don't do enough water changes in a week your ph will go down until you change the water making is very dangerous for the ray. if you test your ph in the morning and at night when you do a water change until the next you might see the ph go down. Good luck with the ray!!
 
That nitrate is nothing to worry about

You will be fighting a losing battle to try to get it much lower

Rays don't seam to be affected by high nitrates so as long as you do 2 x 25% water changes per week you will be fine

as T1KAR stated, that level of nitrates is nothing when it comes to rays. people even breed rays in nitrate levels over 200.
what you should be concerned with is ammonia, nitrites and pH swing. those are what kill rays more often than not. even temp differences don't really bother them.
i used to do 50-75% water changes on my 400 gallon system and anywhere between 25-40% of it was cold water, we're talking 60 degrees. they had no issue with this. in fact, water changes like this are similar to the rainforest when the rains flood the waterways and cause the temp to drastically drop, inducing mating between rays.
