i did a 50% water change today,tested it about 10 mins ago,and wow my nitrite is at 5.0.ph is at 6.8 amionia is at ...
if there hadn't been anything in the tank for those 8weeks then there is no bacteria in the filter
to cope with the waste that the fish are producing.
do you have any friends with fish ? if you do,ask them if they would be kind enough
to donate some filter media to you,if not then you can add beneficial bacteria called *cycle*
however many people are not sure exactly how good it really is.
water changes using a dechlorinator is a big must for you now until your levels spike
and come back down, you may unfortunately lose some of the fish,as they are not hardy
enough to withstand the cycle process.
you'll be pretty plain sailing once the cycle is through,then and only then is it to add more
fish at a slow rate,so the bacteria bliuld up enough.
adding live plants helps,and there are quite a few you can have that are easy to look after.
my tank has been up and running for over 4 months,i waited 2 months before adding any fish,i noticed yesturday that some where scraching themselves on the rocks and plants i have in there.so went and bought some salt for it,as i read that it helps them.
checked the water again today,
amonina is at 0
nitrate is at 50
nitrite is at25
ph is at 7.2
should i do another water change as i did 1 yesturday?
good idea on the plants,they will help eat up nitrates.
you can do another if you like.
i really would if the fish are gasping at the top of the tank.
how much flashing are the fish doing,are there any visible white spots on them ?
i did a 50% water change today,tested it about 10 mins ago,and wow my nitrite is at 5.0.ph is at 6.8 amionia is at 1.0 nitrate is at 25,amonia has come down alot but the nirite has gone crazy
It sounds like your tank is cycling again. I would say this is due to you vacuum the gravel every week. I would not disturb the gravel. At most you can run the vacuum over the gravel to pick up waste at the top but you don't want to disturb it because that is there the good bacteria will hide.
Also make sure you are using API Master Test Kit or a water solution to test (they are more accurate)
Your Nitrite is Beyond High. that is deadly to fish
The ammonia is ok, but better at 0.
Your nitrate levels look alright, better under 20ppm though.
Your best bet is to use Prime water conditioner and to do water changes daily or every other day until your tank settles.
If you ever have Nitrite or Ammonia above 0ppm than you should do a water change.
Good thing you are getting plants, that will help a lot!
