Have begun to add 100ml of vinegar to my Kalk "system". It's actually a 5 gal water container with an air line coming out of it. I use a air line valve to control the drip and it serves as my ATO. I have to refill every 4-5 days. I've had good result so far, sps is really starting to color up. I am also dosing 5 ml of vodka daily.

My wet/dry has a section right after the return and since I don't have a filter sock I cut squares of 100% polyester felt, which is what filter socks are made of. I cut them a little big so that there is no bypass. Great improvement with all the above steps. Hair algae almost completely gone. I've also gone to a DSB in my main tank since there is no room in my sump.
