Out Of Nowhere Cloudiness?

[Jenste]

This afternoon I noticed my 30 gallon corner tank was immensely cloudy out of nowhere - - Has been established for almost two years (it will be two years in the end of september)....nothing new has been added to the tank - - it is barebottom, with a few pieces of driftwood...

It houses my 3 adult ACF.
cleaning schedule is the same as always - 25% WC a week, except for the end of the month I do a 50%.
Ammonia -0
Nitrite - 0
Nitrate - 15ppm

yet - - cloudy cloudy water - white cloudy, not green cloudy.
haven't changed the filter media, but give it a rinse every other week in the old tank water to get any debris off...



any ideas about this all of a sudden cloud? its bad enough where I cannot see the filter intake tube. I just did a 25% water change and it didn't really help much at all

I know that cloudy white bacterial blooms are fairly normal in brand new tanks that are cycling (it happened to me twice during my cycle). I had to do 90% water changes to clear mine out. But an established tank like yours - I don't know. Other threads I have read say that blooms will normally clear out on their own. But I don't know how to handle it with critters in the tank. Perhaps larger water changes.

I had this and small water changes weren't doing anything so I was very naughty and did a 100% water change and it's been fine since

i figured a 25% weekly for three weeks, with the fourth week being a 50% wasn't small!

The cloudiness was mostly cleared up this morning... I don't understand it lol
