How long does bacteria bloom last?

How long does bacteria bloom last ? It been few week, few week event are:

Cycle tank 4x2x2. For 2 week with LR, ammonia n nitrite drop to zero water are clear,

3rd week added more LR 17kg, 4th week ammonia n nitrite rise and drop to zero, cloudy for 4th and 5th week, added wave maker yestday, cos can afford only one at the moment Mp40

Water still cloudy, what happen? LS put in 4 th week with two sifting star and two turbo snail, one snail n star die last nite

Did you put sand? Running a filter wool will clear most of it. Thereafter you can use carbon to polish the water crystal clear. Check your phosphate ... It may be killing your live stock .

Thanks, yes I put sand when tank arrive, which is 1 month ago, Phosphate I did not test as during cycling thought the 4 parameter should be ammonia, nitrate , nitrite, PH, of cos the first 3 are more crictial. Carbon I added last few days that why my LS is dead? Using active carbon Sera Brand. I need to confirm is the cloudiness cause by bactieria bloom? can UV helps? In such cases, shall I add more clean up crew as the diatom are getting out of control soon

How long have you been running the carbon? Give it sometime to work .. Better if the carbon is in a FR. If you just drop the bag of it into the sump.. It won't work well. Good carbon should not kill any livestock .

Suggest you start controlling your po4 . I have live stock that is dying without reasons even in the second month of cycling.. Even though my nitrates was less than 5 ppm ...things only started to turn around when I started looking at po4 and use rowaphos to bring it down. Po4 even at 1 ppm is considered high...

ok I will look into PO4 tonite but I m using NP reducing pellets in FR and connect outlet to skimmer, if there is High pO4, what level is not acceptable and what should be done? I have chaeto in my sump as well, withPL light on for 10hour opposite of my display tank

thanks, added another Tunze wave maker think is the aeration or circulation of water now it seem better, read it in the interent that bacteria bloom you need lots of circulation, or maybe the wave maker have cover the layer or denitrius with sand.

If phosphate exceed 0.1ppm,it will retard the growth of corals and green alage will Start to bloom almost instantly.
