Cloudy eye both internal and external

Cloudy eye both internal and externalCloudy eye both internal and externalHey bros,
Anyone have any experiences with this? Read up online that cloudy eye can be a result of internal parasites, such as protozoa or flukes, onset of cataracts in fish, and bacterial infection due to injury。 Poor water quality is also one of the more common causes especially when the ph drops too low。

Yes bro internal cloudy usually cause by protozoa and usually difficult too cure。。。even when cured may still cause the loss of vision。。。
>Originally Posted by Fingerling Poor water quality is also one of the more common causes especially when the ph drops too low。 yes, agreeded on this。 Previously I noticed my aro tend to develop cloudy eye when my tank PH is very low。 Low as in around 5。5 to as low as 5。 Back then i do not have a ph monitor。 It is good to monitor PH constantly as I believe very low PH tend to lead to other problems IMO
>There is a school of thought that too low pH will kill the benefitial bacteria (BB) and thus resulting in poor water quality。 Once the water quality is deteriorate, many problems and illnesses will occur。
what is the acceptable low pH level such that the BB can still survive? Anybody has the answer?
On the other hand, low pH may not necessary be the cause to illness problem。 Rather, we can view low pH as a result of nitrification cycle and it is closely associated with high nitric acid and high nitrate。 I believe it is the high nitrate that create havoc if you dont change the water regularly。 Too high the nitrate may cause reverse nitrification process to take place whereby nitrate may be converted back to nitrite and ammonia which becomes toxic to the fishes。
>Originally Posted by average_cc Yes bro internal cloudy usually cause by protozoa and usually difficult too cure。。。even when cured may still cause the loss of vision。。。 Yes, but how do you identify whether the cloudy eye is internal or external。 And what are the recommended steps to take to cure protozoa any tips on this bro?

Rather than the tedious WC regime, would you recommend plants in a filtration system to fight high bioload and nitrates? Ive seen people who added plants into their filtration systems and survive with just once a week WC while their tank is fully stocked with monster fishes。
>Did some reading through on cloudy eye problems, thought id share this useful info。
Several causes of cloudy eye
1) Water quality ( Most common factor that leads to cloudy eye, can be cleared with a good WC)
2) Injuries from fighting or sharp objects。
3) Cottony growth over lens of eye ( Saprolegnia Fungus )
4) Translucent film over lens of eye ( Gram Negative Bacteria )
5) Iris around pupil becomes cloudy ( Gram Negative Bacteria )
6) Swelling and redness surrounding the outside of the eye ( Gram Negative Bacteria )
7) Entire eye becomes cloudy from the inside out ( Parasite/ Fluke ) This is definitely much harder to cure。

>IMO, Bad water is always the root for all causes,Aquarium the biological filtration system (sump) has it set back, a close system functioning very much a pico E-co cycle unless incorporate a vege filtration ending the nitrogen cycle。
The other alternative to the reduction of nitrate is by WC, too little too much? many do not consider the nitrifying bact。 are very much venerable to PH, termal or other factor (medication etc。) shock。 The bad thing (failure of bio-filtration system) non notice until fishes are sick and dying from it。
Imo, Understanding to manage and maintaining of the considered filtration system before embarking the introduction of fishes into tank will levitate/enhance the interest of fish keeping further。
>Thanks for sharing your opinions bro regular WC is indeed the best way to fight against such problems。
>Cloudy eye usually is due to water problem?
