ICP analysis after 4 years, no water change

[Koty]

IMO there is a misconception regarding CO2 . Its rise in closed rooms is not as important as the fact that it’s a very heavy gas (heavier than water but is still a gas). So it tends to accumulate if not forced out of our tanks.

I always tell people not to rely on home kits because I’ve seen this issue too many times.

I even have it written in my K DIY:

I used the Salifert kits for a very long time and checked it with the Fauna Marin multi standard. However after all the warnings I moved to the Tropic Marin kit which is not very friendly but probably accurate. That kit gave me the concentration I got at the ICP. So now I will Waite hoping it to decline to normal values.

I forgot to mention I have. Refuge with Chaeto that is blasted with 180w plant grow light Ang the small Kessil for refuge. Light is on at night. Chaeto is growing very fast. I need to dump it every 2-3 weeks. Sump is full with Austria and recent addition is a big yellow spong. That is why I am happy silica is present.

Do you add any silicate or know how it is getting in?

The analysis of the rodi/resin treated water showed silicone

OK, that's not unusual. :)

The ICP claims the following issues:
CO2 is very high
pH is a bit low (7.59)
Sulfor is low
Potassium is high (A known issue, as too much was added based on the Salifert K kit)
Boron is a bit high.
Strotium too low
Fluoride very low
Iodine is very high, 0.189 mg/lit
Silicon is high (I thought it was low based on the Salifert kit)
Manganese is very high, one ug/ml

CO2, if it's true, may be too much carbon dosing?
What is the best way to add sulfor?
Iodine may be a result of feeding Nori?
Am I dosing too much A & K elements?
@Hans-Werner ?

Yes, likely the A- & K+ Elements dosage is high, hence the high iodine and manganese concentrations. The are the principal elements of the A- Elements and in the K+ Elements respectively after strontium.

 

[Koty]

Thanks. I guess I will lower the doses of A & K. The strontium however is very low but according to Randy (and my corals ) it is has no effect. Notably the Strontium decreased by 40% in 4 years.

By the way I think you have a problem with the Amino organics. It does have bacteria or fungi growing in it. :

By using the skimmer I assume you are removing the waste from your system. And that will remove salinty over time also ? I e your physically removing tank water when skimming and I'm assuming auto top up with RO. Do you add salt directly to the tank or how does this all work regards to salinty?

Indeed the skimmer takes out some tank water. But I think that you do not understand the basis of the Balling dosing system. Since I have a lot of corals. i’m adding 420 milliliters to the tank daily so my problem is actually that the salinity is going up so from time to time I have to take out water from the tank.. there is no situation where the salinity is declining only creeping up

 

[jt0117]

Understood balling method is new to me. I have a year old tank with refugium and skimmer and was thinking about a no water change method.

 

[Randy Holmes-Farley Verified Community Expert]

Using a properly balanced two part does effectively make small water changes.

At an addition rate of 1.1 dKH per day effectively changes 2.4% per month when salinity is maintained.
