I got my 20 gallon off of Craigslist last night. They had removed most of the water and just left one false julii cory (he's HUGE) and one MM platy in the tank so we could move it easier. We got it all set up last night and I checked my water parameters this morning.
pH 6.6
ammonia 0.25
Trites-0
Trates-20-WOW! That's after what I'd consider a 90%
water change.
It came with a very sludgy, very noisy Aquatech filter that I'll be replacing today. I have sponges in my cycled tanks to put in the new filter (Penguin Biowheel 150-I like those). I'm also going to get a heater (paranoia) so I can keep the temperature steady.
As far as the nitrates go, 50% water changes daily until they come down to 5-10. Does that sound right? I keep my other tanks at 5-10 nitrates because it seems to bring out their color more and they seem much happier.
When everything with the water parameters is resolved, I'll be moving the platy and cory to another tank and putting either a convict, a jewel, or a krib cichlid (I haven't decided yet). I have to do the research on the proper PH levels for the cichlids (I have crushed coral if I need to increase it).
Please let me know if my plans for the water changes and the filter sound good.
Thanks
