Hi everyone, we have a new tank that cycled for almost 2 months & has been set up for over a month with 9 male peacocks & haps. everyone is happy & getting along fine minus the occassional chasing. we have the dreaded diatom invasion & the sand looks like ****. we have PFS. any suggestions? i did add some plants last week & have nerite snails coming. all water parameters are fine & we have 2 canisters running (one with rings & balls & 1 with filter floss). i know that the diatoms will eventually go away (the rocks look horrible too) but i don't know what to do with the sand. i forgot to mention that i did stir the sand up a few weeks ago & ended up with an algae bloom. :?
