Crystal clear water! And my temp has been swinging bad I know (from 78 to 79-80). I don’t get how I just installed a brand new 12,000 btu air conditioner in same room as tank. I have a RSM 130d (34 gal) two days ago removed stock hood and lighting and mounted a hydra 26 hd which I thought for sure would help with temp going up but nope. I really don’t want to buy a pricey chiller plus I read draws alot of power going to try the clip on fan blowing over top of water in hopes that’ll help keep it stable.
