I added a picture with the light off so you can see the evident tint against my white shades.
I've in the last couple months noticed a yellowish tint to my water. Usually has been keeping very clear the many years I have the tank. I only have a hippo and 3 damsels now. Usually do water changes every 2 weeks or so. It's a 75g. Active for 6 years now.
Had some unfortunate events in my tank since September as well. Had an Emperor Angel get popeye. Dosed the tank with antibiotics making it quite yellow with a bad smell. Used some Chemiclean to make it crystal clear. It eventually recovered but did not eat so it died. Got a calico crab right after. That died too after a few months. Not sure why? Maybe bad food? Fed it silverslides and she enjoyed them a lot. Strange. Hippo Tang and damsels been acting just fine all throughout. May run the Chemiclean again.
Is my protein skimmer not sucking enough out? Maybe I can take it out of my sump and let it run from the main tank externally for a while.
Id like to resolve the issues and keep the water clear before I add more fish.
What is the problem and what can i do to fix this? Thx
