| Gerri,
What type of substrate do you use in your tank?
Has this always been an issue or just a recent problem?
If recent, what has changed in the tank?
I am asking these ?s because it seems odd to me that a tank which has been established for a year should be able to deal with the amount of wastes an Oscar produces or multiple cichlids so long as the tank is big enough for it.
A 20 gallon tank is not large enough for an Oscar and I am assuming that it was pretty large when you eventually removed it from your tank? However, the amount of wastes produced by an Oscar can easily be equalled or surpassed by keeping multiple cichlids. In fact, it is many people's opinion to intentionally overstock a cichlid tank for various reasons and do not have a murky water problem.
Do you know what types of cichlids you have right now?
I think that you have other issues creating the tea like color of your water. It sounds like you are familiar with the concept of vaccuming the substrate, so if you have practiced doing so since you shouldn't have too much build up of wastes that would cloud the water. If not, it may help you out a lot to change the substrate or take it out and clean it well, however this could cause a mini-cycle in your tank so be careful. |
