Water parameters

[Ccccz]

Hi all, I started this thread as I thought it may not be relevant to my previous thread about ich.

Bottom line remains, fishes are dying. Perhaps it's ich, perhaps it's parameters, so I need your advices.

Tank is a 2 feet cube with sump. Bubble Magnus nac 5 skimmer. Yes, there's ich as I notice my clowns and tangs get white spots. Some days the white spots do disappear.

Only treatment is seaweed soak in garlic. Although garlic is debatable I still give it a shot.

Tank running for around 10 months.

Corals and inverts are ok.

Nh3 and no2 is zero

No3 50ppm

Po4 0.5

Ph 8

Kh 7

Salinity 1.021 I know this is low. My gradually increasing it.

3 clowns

2 chromis

1 6 line wrasse

1 yellow wrasse

1 PBT

1 yellow tang

3 cleaner shrimps

Mainly Lps corals.

Am I getting things right?

Thanks for the kind advices.

First thing bro..Dont gv up and fight itch..

Your nitrates Are High..Maybe Thats stressing Fishes

Also Upping You Salinity Slowly

Also You can Try Polylab Medic..FYI Its Reef..Safe..You Also Stated That is off and on?.so i think polylab medic..would be a good try..

Try tunning params And Using medic

Whats your calcium And ( MG)?.

These might be too high..or low causing stress....when did the itch start? After Adding The PBT?..

I haven't started testing Mg and Ca. May try the poly lab med. I tried using AZ NO3 for my no3. Since nano tank quite hard to control. At 1 point, no3 shoot up to dark pink. 100ppm I think. Az no3 stabilize it but adding livestock naturally raises it again. I started dosing but got a feeling my fishes may be stress by it so stopped. May start the az no3 cycle again.

Run Some Biosphere..will help

Do u have any other form of nutrient export?

[Ccccz]

I have biosphere. Run for about 2 months. Place it in skimmer compartment. I figured it has the most flow there. Come to think if it, after 2 months its abit disintegrated. Also have seachem di-nitrate. A clump of chaeto in the dsb refugium. Change from led to 1 feet t5 light in my sump my chaeto still struggle with growth.
