Me again…hope you don’t mind if i bother you with another question. I’m qt’ing my clown out of precaution and figured i would use the opportunity to pick up a few more fish. So as of now i have the clown along with a goby, blenny, and royal gramma in a 10g setup. All the new fish are really small so not much bioload. My lfs guy is advising me to opt for heavy biofiltration, skip the water changes so the medication levels are stable (also dosing metroplex and nitrofurazone) My question to you is it safe to take this route and continue to dose meds as directed without water changes? Everything I’m coming across online concerning metro and nitrofurazone says to do 25% wc’s between doses. Obviously ammonia could be a concern but I’m running a Seneye, removing all uneaten food every day and have some well seeded ceramic media in the tank. I’m just confused what the water changes are for exactly. Also i haven’t found any great info on how often to dose nitrofurazone. So far ive only dosed it once. I’ve dosed the metro twice and am due for another dose tonight.
