- yes, very possible.. the water could still be bad..
answer these questions, please:
-what was the ammonia and all other water parameters for the past few weeks?
I am not fkn able to get amonia test around here. So i dont have a slightest idea on that one. I have changed water 3-4 times per week with that in mind to keep the tap water- and tank water as equal as possible... but still i did obusly fckd this whole thing up.
As i have told earlier the PH dropped at one point. At the same time the nitrate level was too high. This happend when i was gone for some days (stupidity). Other than that the PH have been stabile at 7, and i have had controll over the nitrate levels.
... i have realized i prbly was too quick and eager when introducing rays to my tank. It all went too fast. And of course(!), i shuld not have gone on this little "vacation"- at that point. I fear this is the main reason this have been a total fiasco so far- and that these sick rays are a resoult of this PH/nitrate "crack" two-tree weeks ago..
u still haven't told us what the ammonia levels are or have been..this is very important!
Wish i culd.
(examples of parameters which u may not observe, but should..)
-KH (alkalinity)
-GH (general hardness)
i need u to find out what they are.. from ur earlier post:
it seems that u have fluctuating Ph problem.. this
may mean ur KH is probably pretty low..
-what are ur water parameters now?
No2 - 0mg/l
No3 - 5mg/l
KH - 6
GH - 3
PH - 7.
-what are the water parameters of ur tap water?
No2 - 0mg/l
No3 - 0mg/l
KH - 6
GH - 6
PH - 7,2.
-are u sure the tank has properly cycled??
I am shure it has now, but i am also shure it was NOT at the time i introduced the rays.
duh
-how long has the tank been set up for?
Around six weeks i think.
-have u had all 3 filters for that same period of time?
Yes.
to be honest it doesn't look to serious..
What doesen`t look serious? This whole attemt to keep rays, or do you mean the actual state the rays are in? Excuse me for asking- but i am not shure if i understans you correctly. then again u haven't given us enough info on tank. if the ray totally stops eating and begins to curl up, then u know something is very wrong..
