Just a small little question im interested in. When keeping an octopus, water parameters are of course...the most important parts and just out of curiosity, do the parameters slip very quickly? Like for example...how long would it take until the pH level starts to lower or go too high? How long does it take until the salinity slips or the nitrite/nitrate? I am aware that regular water changes and filteration should always keep these parameters on base and preffured for a Bimac, but do these parameters slip and go too high or too low and have to be adjusted quickly? if so, how long does it usually take until they do? I hope pH buffers work good.
