water become cloudy after water change...

[Derek0925]

My main tank is currently into the 4th week of hyposalinty...decide to do a 30% water change at 1.009.

Also took out all the live rock for about an hour to do a re-scaping and put in rainbar to improve aeration....after change water....add some antichlorine for marine water and trace element calcium both from seachem.

After that the whole tank turn water cloudy...it has been 2 days still cloudy....

1. Could it be the live rock left in the open too long and died?

2. The BB in the sump tank died?

3. Reaction from the seachem product?

All the fishes still ok.

The tank is oreadi 4 mth old....i doubt bacteria boom....

NH3 - 0

NO2 - 0

NO3 - 40

PH - 8.4

KH - 11

Any expert bro can help me?

[minsmarine]

ur KH ?

Nothing wrong with all your doing , may be you does tomuch calcium so become calcium settle down.

Should be gone by 3rd day.

Are you using an overflow filter?

I once encountered the same problem and it was caused by the way I arrange my rock. I was advised to rearrange my rock and after rearranging the water clear up.

[Derek0925]

Bro Minsmarine, my KH is a stable 11.

Oic...i oso thought could be due to the seachem calcium.... but i follow the direction of putting 1 capful for every 20 gallon. my 4ft x 2.5 x 2.5 ft is approximately 140gallon. So i put in 7 capful. Thought it should be ok. But the fishes so far no abnormal behaviour.

Bro dragttag, mine is a sump tank overflow. How come the liverock will cause it to be cloudy leh? Infact i purposely add in rain bar to increase the aeration so should be alright.

For my case, my LR arrangement is preventing the dirt to be pushed to the overflow box.

The dirt keeps getting bounced back and circulating within the tank. Hence, the cloudiness remains.

bro, my is top overflow...so shouldn't be a problem....

i think u add in too many and caps of the calcuim , used to have this problem then found out 2 things is the salt fresh i mean fine and not in lump and second space out the timing in putting the calcuim let the tank take it first then pour again too much at 1 time hard to dissolve all and it snowball

My tank turned cloudy cuz my bio filter was choked from overfeeding.

[Derek0925]

To all bros....my tank turn super clear today....thank you everybody for your advise....i love you all....

[minsmarine]

It should be Ca perticipation. It happend most of the time. Normally cleared in 2-3 days depended on how much u add.

It's confirmed that since your KH is 11dKH and I guess your PH is > 8.1 it's highly to perticipate. Your Ca should be beyond 450 now.

[Derek0925]

thanks bro minsmarine...

but i dun keep coral leh....450 is good or not?

I keeping FOWLR....

[minsmarine]

Nature Seawater is Ca 420 and KH 7-8dKH

If your Ca is 450 and your dKH is 11-12dKH, just keep it as it. If you want coraline algae. IME, high KH 11 and 440+ Ca promote.

Oh yea, your PH is around 8.2+ I guess.

If the problem persists, it could be an ionic imbalance...

get some activated carbon and add into ur tank's chemical filtration if u had not done it yet.

it helps
