Yes I cleaned all my canister hoses with my tube brush and water parameters are still good
I have a fx6 and 407 in the tank which is 75 gallon. Fx6 has 2 trays of bio media and top tray has course sponge and polyfil (ran out of polish pads) and 407 has course and polish pads on bottom, bio media in two middle trays with purigen bag and top tray poly fil. Everything has great for months up until Friday. I used to have a sponge filter but I cycled it for my quarantine tank a few months ago.Maybe run a "Micron" filter just to remove the particles?
I have sand but it's not that ultra fine sand. I use caribsea cichlid substrate and I do a light surface vacuum every other week when I see fish waste, usually next to one of the rocks in the tank. I have 14 after having to rehome one not long ago.Starting from the basics: You have plenty of filtration on this tank. This is the tank with 15 peacocks in it? An Fx6 + 407 is plenty. After a month, these are likely still pretty clean. Do you have pictures of what you mean by disgusting? Really as long as it's not so clogged the flow is constrained it's probably fine.
Hard to tell what the dust is, could you send pictures? It could just be little air bubbles. I'm a bit skeptical that the white flakes are due to biofilm, since biofilm by definition will be most stable when it's not disturbed. Your tank is going to be cloudier after you clean the filters or vacuum the gravel, but it should clear up over a day or two.
What's the substrate? Are the fish showing any signs of irritation, like flashing? If not I'd probably just ignore it.
Everything in the tank will get biofilm, no sense fighting that.
Fasting once a week in my experience isn't likely to do too much to aggression if you're not having aggression issues now.
I purchased the substrate brand new and rinsed thoroughly in February. Yea calcium buildup is inevitable.The substrate was new when you got it? My guess is the cichlids are digging around and releasing fine pieces of dust from the substrate. Even if you cleaned it before you put it in the tank, it's impossible to get every single piece of dust off the sand. If you dig up the substrate yourself with a siphon, do you see the water getting cloudier? I think the thing to do is to vigorously vacuum the substrate whenever you change the water for the next few weeks. Eventually the dust will go away.
Calcium buildup is pretty hard to avoid, if you want to clean off the glass that's fine but the fish won't care either way. It's hard to fight in a hard water tank.
Yea that's what I did the other day. I have tank toothbrush just for that and for my wavemakers lolIf its just the ring at the surface, a stiff toothbrush cleans it right off - as long as you don't wait too long to scrub it. I have that in my tropical tank because my tap water has pretty high GH and KH.
I've tried seachem clarity but still have the particles. I'm going to do another water change tomorrow and try that.From what I can see in the photos that doesn’t look like sand to me.
I had something similar in my tropical tank - added JBL Clearol which is designed to remove micro-fine particles (sure there will be equivalent other brands) and 24 hrs later the tank was crystal clear again.
