i used to run everything at 86f. now i took all the heaters out and just run them at around 75f the house temp goes between 70-80f tanks change accordingly. i used to have some iffy plant growth and some plants would just outright die. now all the plants are flurishing. all my small/young aros i will have at 80-86f to get some fast growth and to run a low sick risk on them.
