Lower ph for my stingrays
- Thread starter Rtm101
- Start date
I have a friend that has rays and his ph is 7.4-7.8 out if is tap and he doesn't lower it. So maybe acclimate the ray to the 8 and just keep it there probably better than fluctuating ph.
Just leave it. I have far more problems dealing with tap water that comes out at 9 and drops to 6 in a couple of hours. I would actually prefer to have PH8. The two pups I have were bred by 'Just Toby' in Water that is PH8 and very hard. At least you do not have to worry about your tank crashing. Just take a bit more time acclimatising your fish. There are quite a few people on here that keep and breed rays at PH8.
I have had ph crashes cause me more problems than any other more commonly panicked about issue on here.
The only thing to keep a more regular check on is Ammonia as it is more toxic at PH8 than a below 7 reading, as ammonia forms less toxic ammonium at acid PH.

Sorry to interrupt but my ph is at 6. Leave it or raise it with some crushed coral? Not sure if the same applies? Thanks
In your case I would add a small bag of cc just to keep the water buffered. other than that if your rays are already in the tank I wouldn't bother increasing.
I'm with the masses, it's safer to acclimate them to your readily available water params vs. trying to play chemist and never having stable params.
My rays have been in 7.5-8 for 3 years breeding and doing fine
You can add stuff to bring it down but it won't last long
Best to just leave it at tap water big ups and downs are not good for rays
Keep it stable is the key

X2. Take notes , you are in the same situation as me. Add some coral gravel for a constant buffer for the KH. Filter bacteria use 4 grams of calcium for every 1 gram of ammonia processed. Therefore tank water with a ph of 6 can very easily crash due to the biomass of large fish like rays. I have learnt this the hard way. Aquaman (Richard) will testify to this, as he always has coral gravel in his filter system for this reason.

Sorry for disturbing the the thread but trying to maintain a tank for large fish at ph 6 us nearly impossible long term. Filter bacteria are on the edge of their environmental active range, they barely function at ph 6. PH 6.5 and above is far more stable. Below 6 ammonia only exists as ammonium and filter bacteria die off/are dormant, so if you raise the ph from 6 to 7, it is advisable to do so slowly. Adding coral gravel is fine, don't suddenly use a ph plus product in a bottle. Or you will have mini cycle occur while the filter bacteria catch up to the increased ammonia.

Thanks guys. Yes I have used the crushed coral but over time it had dissolved away and I have added a hefty amount of wood. I will add some once again in my canister to get things back up to 7. Thanks all
