This tank has been setup around a year and the plant growth has been really amazing. The light is on 12 hours which may be part of the issue. It is a little light on stem plants but it does have emergent plants and floaters. There are ~25 fish, 100+ neocaridina and a ton of snails. While each tank is different, i run this tank exactly the same as my other tanks and this is only one with cloudy problem. I have read all the articles and am a bit stumped.

Recently i tried reduced feeding and water changes which eventually cleared it up to some degree which I then resumed my twice daily feeding and no water changes. I assume the feeding is leading to bacterial bloom. The only real difference with this tank is the number of shrimp.

Any insights? Should i just reduce feeding? There should be plenty of shrimp/snails to clean up any leftovers…

these pics are after 10% water changes yesterday and today. I dose with flourish a couple times a month mainly for the floaters.

Is it bacteria or just free-floating algae? The snapshots give it a greenish tinge which is exactly what I have in my filter-less breeder tank. I assume it would all but disappear with some type of "water polishing" system, but for right now, I'm fine with it:

Hadnt really considered that, the light it definitely on long enough… no indication that it is green upon inspection after water changes unless its very subtle. Ill have to do an independent check. is it possible to be just a little green and never go all the way? I have noticed varying levels of cloudiness.

also i added huge amounts of daphnia over the summer but i dont think my fish left a single survivor Lol.

Nice tank. I wouldn't do anything drastic like reducing the photoperiod below 12 hours.
Have you tried a midday siesta? Three to four hours off during the midday would you help control algae without diminishing the required 12 hour photoperiod.
I would not add Flourish unless you actually see iron deficiency in the floaters and/or they start to disintegrate. I suspect your tank has plenty of nutrients, as evidenced by the cloudiness.
Yes i was adding flourish periodically as the floaters were disintegrating. Ive been usually adding it when i see browning/paleness. I could try a siesta. One of my lights has an adjustable intensity that im going to try first just because all my tanks are synced up on that same photoperiod.

Reducing intensity hasn’t helped noticeably with this tank so I am interested to try the siesta. Reading back on one of your original posts you say you use a 5-4-5 schedule with ambient light from a nearby window. You also refer to this photoperiod as more than 12 hours and suggest I shouldn’t drop below 12. Are you counting the 14 hour period with the siesta as a 12+ hour photoperiod? To rephrase, with the plants only getting 10 hours (5+5) of light does this still count as a 12 hour photoperiod since there is no prolonged period of darkness? I have a rope light overhead that turns on before tank lights come on and off to offer a bit of adjustment for my fish so they’re not shocked which I would use during the siesta, but its nowhere near the level of light that a window would provide.
