Hello there, I was looking at some tanks ideas and thought about my rockwork to left rear corner would that be possible to make more open space in the midsection is there a need to be space between the glass and rocks then if I move them? And would that help with the flow (currently fighting cyano) don't know what to do since water was just checked and nitrates is on 0 and phosphate is 0 too... LFS guy told me to try slowly dosing phosphate remover and doing small water changes every day since cyano or something else is aggressively eating it away therefore the nutrient balance is helping cyano to thrive. By the way my tank has no filter except live mature rock and sand.


guys any other suggestions or ideas what I could do to make this tank better?

that's why I kept it isolated
