i recently got rid of alot of my fish and re aquascaped my tank to decrease my bio-load due to high nitrates . the nitrates were at a constant 80ppm to 90ppm. i properly maintained my tank with water changes and dosing of B-ionic. i recently added a hot 5 gal refugium growing chaeto and slowly started to notice more green and pink coraline growing back on the tank walls.I had none. i also added a rdsb about two and a half months ago. my nitates are now dow into the 10-15 range but my alkalinity will not decrese. i do 20 to 25 gal water changes twice monthly and run a sump with two skimmers. i would like for my tank to get back to normal reef if you know what i mean. anyone have any insight PLEASE?!!!!!!!
