I am only 2 days in. I set temp to just shy of 88 on day 1 so even lowest temp would be above 86. Today, I am keeping temp at 89.2 because my
Betta is in really bad shape.
Disclaimer: DO NOT USE HEAT + ICH MEDICATION. Follow the medication instructions, exactly. Including tank temperature.
86 makes ich infertile, but it will still finish its lifecycle from spore to parasite. 89 is theoretically deadly for ich.
From what I gather, the biggest problem with heat increases, relating to heat’s impact on fish, is not the heat itself. The problem is the capacity of water to hold oxygen. The more heat, the less oxygen water will hold. If you are going to heat your tank, to 86+, please add
air stones! I know they aren’t ‘oxygen packs’ for your fish, but they are really good at agitation which helps keep the water as oxygen saturated as possible.
I also increased the photoperiod of my plants to 12 hours so the plants (including algae) could help with the oxygen issue.
I chose to go to 89 because my Betta is my favorite fish. I didn’t jump straight there, I just upped the heat a bit, checked the
thermometer in about 45 minutes, and tweaked again until I got where I am now.
It sucks. I am sorry someone else is going through this too. I wish I could tell you a success, but as of now, I don’t have any to share. All my
ember tetras are alive and well. All the
barbs are dead. My
cherry shrimp seem fine. My entire snail is active, so I assume it is fine as well.
Google says the max temp for a barn is 81, so perhaps the heat killed them. Then again, google says the max temp for a Betta is 80, and mine is fine, other than super lethargic, ich covered, and clearly struggling...
