Sorry I didn't get back to this thread until now
, The hair algae is being fueled by the nutrients in the tap water. I would recommend manual removal of as much as possible, using a bottle brush twirling it in the hairs, using a toothbrush (bought for this purpose) to scrub as much off as possible. Remove as much from the tank as possible. You should invest in an RO
filter which will remove nutrients like nitrate and phosphate (added to water supplies to combat lead piping in older houses) before they get in the tank. I would recommend turning your lights off for a week and running them for no more than a few hours a day, until the nutrient problem is resolved. I would also recommend a protien skimmer for your tank, your gonna need a pretty big one for a 220g tank, you might consider a downdraft. Once the nitrite and ammonia are 0, you should do a large water change using RO
water and you can add a clean up crew to help with the hair algae, some blueleg hermits and an assortment of herbivorous snails. Hopefully others will jump in with some other suggestions as well.
