Before everyone screams about the load my water perameteres are perfect. Between my filtration systems, plants and weekly water changes will the boxes are perfect and fish are great. Been doing this a while and I have a strange knack/luck when it comes to keeping levels in check. There's also a ton of hiding and sight break areas.
One thing I started doing during water changes recently after noticing some flashing (possible ich entry from lfs
purchase I know to be careful with) was putting half dose of paraguard in and it seems to keep everyone happy and zero flashing since first dose of meds and water change additions. Possible the uv
helps as well.
