Purchased my tank last year and didn't use rodi water and had hard time with keeping fish alive. Punched 40 lbs of rock, sterilizer, protein skimmer,uv light. Then got hurt at work and just left tank running without water changes due to injury. Then I had a horrible brown algae break out. All over my rock and sand. Took all rock out and scrubbed with toothbrush, cleaned sand most I could. Now picked up the 4 stage buddy twist rodi and buddy booster, 20 lbs more rock, multimedia reactor, powerhead. Been doing this for last 2 months and haven't added any fish yet. Taking my time this go around and hope it will be a better experience. Added a few pics.
