I was fighting with mustard algae for 2 years (no success) before I had to replace my liner due to leakage (beginning of last season). This mustard algae start spreading and had a difficult time controlling even with TFP methods. Also, the algae would disappear above FC 10 or so but return below 10 or so. With the "fresh" water (was less than $250 to fill 20K+ gallons), I have noticed that balancing the water was obviously easier which triggered a thought:
Considering the $ (for chemicals, electricity, etc.) and time / efforts (mustard algae never seem to go away permanently), should one consider completely draining then use liquid chlorine (or other chemicals to clean, brush the effected area) then re-fill? Is this worth it or even effective? Of course, this assumes one has a pump to completely drain the water. I hope don't have to consider this option but just wondering.
