Sorry I've been out today....
60" x 24" x 19.5" 125 gallons. Coralife 2x65 watt 10K bulbs.
Excuse me did'nt you state that "Here's what the changes do to my tank, no ferts, no CO2, no florite...." So what is this "Fert Tabs" under some of the plants, "
I don't vacuum the sand where the plants are so the poo is fertilizing". "plants are natural filters to an extent, they don't filter out all the organic waste though" Lights are run for 12 hours. 10 discus, 25 H. Rasboras, 12 Rummynose, 5 otto cats, 2 albino bristle nose plecos, 5 rosybarbs, 2 medium size clown loaches, 2 SAE, 1 lone neon, and a few ghost shrimp that manage to hide well.....Water is 83 degrees, ph is 7.2. I have a 30 gallon shrimp tank with cherry shrimp breeding that's straight playground sand with no ferts and the stem plants are growing like mad.......my tap water must contain some good nutrients. I change that water once a week though......I feed the discus tank 3-4 times a day so they poop a lot, the plants grow slow, but are doing great!
