I have had my 20 gallon with 4 bettas (with dividers) set up for about two months. In that two months, I have changed the fake plants around and added/removed some decor. I have vacuumed the gravel twice. I change 50% of the water on a regular basis. However, I have had absolutely no nitrIte or nitrAte readings. Why could this be??? I have had only had 3 bettas in the fo the past 3 week due to fin probs on one of the guys. I have not changed the filter. I did unplug it to do a WC and forgot to plug it in for 3 days. So I emptied the sitting water and rinsed the filter pad in the discarded water after a WC.
Is my tank simply too big for the number of bettas?? I am in the process of cycling another tank and will seed the 20 gallon with that, but I find it odd that I have absolutely no nitrites at all after two months?!?!?! I am considering downsizing to a 10 or getting a 20 gallon long so I can fit more boys in there and that may help with the cycling??
i would say that if you have removed decor and cleaned the gravel and done water changes you might have removed all the benificial bacteria because thats where it grows on decor and on the substrate as redchigh said i would test for ammonia as soon as possible incase there is a high ammount i would carry out water changes every 3 days too keep levels low hope this helps
Algae is common in a cycling tank. Even if NO2 and NO2 are 0 that does not mean that algae will not appear.
You have several imbalances in that tank. BTW you do need NO3 for the plants and also PO4, here is a link that pretty much tells you abot it: http://www.xs4all.nl/~buddendo/aquarium/redfield_eng.htm
