Where most cichlids live in nature, their water quality is quite high.
What does this mean to a cichlid keeper?
It means
If you are only able to,
or only have the time for,
or only have enough ambition to do a 25% water change in your tanks total volume of water per week…cichlids are probably not the fish for you.
Most cichlids will require a minimum of 50% to 100% water change per week depending on species, will be needed (more is always better)
There are ways to get around so many water changes
Some use anoxic substrate and resins that chemically reduce nitrate.
Some aquarists use large planted sumps where aquatic and terrestrial plants use nitrate as fast as it is produced by fish, but water still to be done to reduce, and or replenish nutrients and minerals we aquarists don’t have the ability to test for.
Or you may want to keep more specized species.
If you want to keep S American Cichlids from, the low pH rivers such as the Rio Negro, Rio Atabapo or Rio Orinoco, and you are not willing to adjust your tap waters pH and hardness to those levels,
these cichlids are not for you.
Average pH of the Amazon basins 6.7
Or…..
If you want to keep hard water, high pH cichlids from the Rift lakes, or river and lakes in Central America…
and if you are not willing to adjust your water parameters with minerals, to at least the upper 7s, preferably 8 or above, or have tap water parameters the meet to those levels naturally, ..these cichlids are probably not for you.
Or if you want to keep fast water, rheophillic cichlids such as many Geophagine, Retroculus, of Tomocichla), or species from the surge zones of the large African lakes that require highly oxygenated wave aerated waters.
If so, they may require strong water pumps, and enough filtration to keep dissolved oxygen high enough to meet their needs, these cichlids are not for you.
Pumps and aeration much stronger than the average HOB, or canister can provide.
