G'day guys, I know this topic always comes up, but just wondering if you guys have any other suggestions. I have a 6x2x2 tank with oscars, rivulatus and sailfin plecos. Today the ambient temp inside my house was 35' and the temperature of the tank maxed at 31'C. So my main questions are, if the temp occasionally goes up, how high can the fish actually tolerate, if the tank is heavily airated? I'm hoping to use ice blocks, but the size of the blocks required, and the fact that I'm usually at work makes this difficult. Removing the hood and lids isn't an option, partly because my fish seem to like to jump occasionally, and I have multiple cats which I cannot keep away from the tank (if I confine them, they risk overheating). I have a chiller on my axolotl tank, so those guys are fine. I am considering buying a portable air conditioning unit to keep the room/tank cool- has anyone done this before? If so any suggestions? Reason I ask this now is because I see the temp for Sunday is forecast to be 38-39. I will get a family member to drop in and stick some ice blocks in the tank... hopefully this will tide them through.
Hey guys, Just tested my water with an API Master Test kit 2 days after doing a water change and my parameters are as follows Ammonia - 0 Nitrite - 0 PH - pushing 8.0-8.2 it seems Nitrates - pushing 40ppm Previously the tank was running at around PH - 7.4 Nitrates - were around 5.0ppm after introducing Purigen. My concern is the rise in the PH as well as the higher than usual nitrates 2 days after changing 25% of the water Tank is 25Litres with Red Cherry Shrimp and a Mystery Snail running Aquaclear HOB with Seachem matrix (and original bio) and purigen Water temp is up from about 25-27 with the current hot weather here. Should I be concerned at these levels? I recently started feeding the shrimp daily, rather than every 2nd day, could this be the issue and should I go back to this? Any ideas are appreciated. EDIT: Water is straight from a Water Tank also
My tap water is naturally around an 8, and this is what I've been keeping my new red tiger oscar in. My thought process was that a stable pH is better than a fluctuating, lower pH. Whether this is correct, or not, is why I'm here. Having googled scholar articles, I can't find much legitimate information about keeping fish in a pH different to their natural habitat. Most of the research centres around the outer limits of acceptable pH, lower than 6-7 and higher than 8. Obviously, I wont be doing this! But, I did learn a little bit about the amazon river, and how oscars adapt to low oxygen levels, their metabolism etc...very cool stuff. Further on, I am not sure what pH fish shops and breeders keep their pH at. I really probably should have asked where he was sourced from, but naturally he's not wild. Next time I will. (There was no pH printed on the glass) So, my question is. What effect will a higher pH have on a farmed fish, whose natural habitat is at a lower pH? Negligible? Or long term suffering? Most forums I've taken the time to read about on this have been slightly hysterical, with little factual (eg., gill function, osmo-regulation etc) evidence to back it up. Also, I don't have access to any paid-for journals, sadly. If any experienced fish keeper can help, I'd be very thankful. I don't want to harm my fisheh! Cheers!
