so after about two years of avoiding pest, the time of tribulation has come, first i fought zoo-eating nudibranchs; hot water dips do the trick so well, i promise. but now i have stupid red flatworms, planaria, jerks. So ive discovered that basically you either wait for them to wane (not looking likely), increase current ( i added another powerhead to no avail) get a nudibranch that eats them, or use medication. My tank is 30 gallons and heavily skimmed everything else is a-ok. any opinions, experiences welcome. thank you.
