Default Cyle A Zeovit Tank

Thank you, I'm using the concentrate version, is that different?
Also after increasing the Potassium to proper level, can i use the automatic potassium iodide tab instead of manual dosing?

The concentrated version is B-Balance Stong which I have mention in my last post. You can dose it as posted there.

I have no experience with the tabs but Iwould expect it does not contain enough potassium to have much of a impact to the level.

I have very hard time trying to raise Potassium to 400. Click image for larger version

I'm using strong version and dosing 4.50 ml / day on 43 US Gallon for a week as ur recommend doses. Its still at 360. Do you have any ideal to raise this tank to 400? Coral is growing but color still pale.
Thank you

400 mg is not necessary, natural seawater has a concentration of ~ 380 mg which is recommended for our tanks also.

To be honest 360 mg is not that low to see much of a negative impact, especially if you have dosed K-Balance for some time already. If the reason would be related to potassium you should see a improvement for sure.

Can you please update the thread with the actual water parameters, your dosing regimen and a list of products you already have ?

Would also be interesting to know how many corals are in the system already also their sizes.

Which kind of carbon do you use and how much have you running also do you use active or passive flow for it ?

If the reason would be related to potassium you should see a improvement for sure < --- I agree with you on this, i will keep dosing K-Balance and maintain potassium level.
Water parameters are in check:
Ammonia, nitrate, phosphate all are 0.
I don't measure CA for a while, while maintain KH stable at 7 (Dosing B-ionic 2 parts equally) and i'm increasing it slowly to ~ 7.5 next Monday with new batch of acros.
Coral quantity has not changed since first post, they are encrusting but pale color, the grow rate is kinda ok not fast not slow.
I run BRS Rox 0.8 Carbon, 4 teaspoons in a reactor running thru manifold plumbing ~ 300-350 gallon/ hour, i may think this is too much. I'm thinking of removing it and run passively in high flow area in the sump instead and introduce the tabs ( Potassium Iodide and iron) to the reactor <--- What is your thought on this?
Below is my dosing schedule: Bak, Star, Food, SP, AA (starting to dose 5 days ago)

To much carbon can also have a negative effect so it is worth a try. I would recommend to remove the carbon completely for a couple of days, after removing it do a 15% water change once.

Next step might be dosing 1.5 ml XTra daily for a couple of days to see if that causes any changes.

Basic water parameters can also have a effect for coloration but as you mention corals are still growing I do not expect Ca is to low.

It can also be the lighting setup or the lighting spectrum.

I run 2 ecotech radion ( 3 gen pro) with default AB+ setting set 15 inches above water, i don't mess with lighting, just use their default setting AB+ on Ecotech lab which i see a lot of people have success with.
Ca on this tank is high ~470 - ~490, I believe time will adjust and bring it down a little so I don't worry much about Ca.

I will update it again maybe in a month with complete details.
Thank you

Hi Alex,
Is nitrate at ~2 acceptable?

Absolute, it will not have a negative impact to coloration but it will come down over the time, no worry.

Default Cyle A Zeovit Tank

So since zeovit system does not need macro algae, i'm just wondering that can i just turn off the light in refugium? i dont worry much about PH since i also run kal and alk 2 part at night to keep PH stable. The reason i ask is because brown hair algae grows so fast in my refugium.
Also is it necessary to keep rock in refugium? i want to remove the rock for better clean up and maintaining.

What is your thought?

Thank you very much

Usually the algae in the sump are not necessary, same with the additional rocks you keep there. Additional rocks are helpful if the tank does contain a minimal quantity of rocks. If you remove them I would recommend you to do this slowly step by step.

Thank you for fast replying.
I also have a concern about excess deposits on the rocks and slightly on sand bed ( brown film algae). I think that excess bacteria population in the tank caused this issue, so i reduce the dosing of start,food and SP. Below is my current dosing.
Total volume: 43 us gallon
Start: total 0.3 ml x2/day ( reduced to 0.2ml x2/day)
Bak: 2 drops ( Monday, Thursday)
Food: 2 drops ( Monday, Thursday) reduced to 1 drops (Monday, Thursday)
SpongePower: 2 drops every other day, reduced to 2 times/week dosing together with bak and food on Monday &
Thursday.
CV: 2 drops x2/week ( Tue, Fri)
Poh extra special: 1.7ml x2/week ( Tue, Fri)
AA: 2 drops x2/week ( Wed, Sat).
K balance & iron tab : run in reactor
Rox 0.8 Carbon: in sump
Are those changes in dosing make sense?
I'm planning to remove about 10-15 rocks slowly on main display ( they are on right side which seems to get more brown algae) and also add one more ~ 200 gph power head on the right ( current flow rate ~600 gph).
Does this all make sense?
Thank you

Just need to be sure with the water volume, are the 43 US gallons the gross or the net water volume of the complete system ?

Also the carbon you run, are those 0.8 liters ?

Hi Alex,
It is net water volume and it is 2 teaspoon of premium rox 0.8 brs carbon not 0.8 litter.

Thank you your plan sound good to me however I would recommend you some changes of the dosage:

Start: total 0.16 ml x2/day
Bak: 2 drops 2 x weekly
Food: stop dosing it for some time until the brown film has gone
SpongePower: 2 drops 2 times/week
CV: 2 drops x2/week
Poh extra special: 1 ml x2/week
AA: stop dosing it for some time until the brown film has gone
K balance tab : if K+ level is lower than 380 mg
Iron tab: remove it for some time until the brown film has gone

G.Alexander
