Fish - I have 2 sm tangs, 1 sm angel, 1 md butterfly, 5 sm chromis, 2 sm clowns, 1 sm wrasse. I only feed 1 cube of frozen mysis shrimp a day, and a 1/4 sheet of Nori for the tangs/angel every other day. My water is 6 stag RO/DI with 0 ppm (new). I've done water changes every week between 15 gallons and 50 gallons. Last was a 50 gallon change 5 days ago. I use a ATO with kalkwasser. I use a Iwaki pump with 1100 gph running main and tapped to run the reactor. reactor has about 65-75 gph running through it. should I use a GFO reactor to reduce the PO4? A biopellet reactor or refugium to reduce the NO3? I don't know where the PO4 and NO3 are coming from with the limited amount I'm feeding. Any help would be greatly appreciated.

Probably can do this,

the water quality is recommended in kh6.5~7.5, ca 400~420, mg1250~1300,

confirm the ro/ri quality and replace the lower salt of kh. First,

start with reducing nutrients, kz base 4 bak, start3, sponge power, zeolite. 400L of water 1 liter of zeolite (1 pack) is placed in the reactor at no more than 400 liters/h per hour. The kz activated carbon is placed in a passive water stream using 0.4 liters and replaced once every 30 days.

The first 2 weeks zeo bak 4 drops 2~3 times a week. Zeo start3 0.4ml daily/night.
Adjust the skimmer to be damp.
Add water with salt. WC5~10% per week.
Observe the change of np, it should be slowly reduced, pay attention to the zeolite flow rate does not exceed 400 liters per hour, observe algae situation should slowly recede. Then prepare a potassium test kit. Let's just listen to what Alexander said.

I can dose magnesium and calcium to increase them. The zeolites (1 liter) have been in the reactor 4 weeks, but I've only been dosing zeobak etc. for about 10 days. Should I replace them now anyway? Also I haven't done the 3 hours on 3 hours off because the reactor is connected to my main pump. Do I need to start over and do the 3/3 on/off? Also I forgot to mention I have 2 Marine Pure Bricks in the sump. You can see some of the corals and algae in these pictures https://www.instagram.com/p/BmI1PzBA...-by=alex.heidt

Hi I looked at the picture and felt that the problem was not serious.
Yes, after 4 weeks, the first time the zeolite was changed 90%, the nutrient salt status was changed to 7 or 8 weeks, and 4 times of zeo bak was given daily for 10 days, added after skimmer. The zeobak added to the day is not added. The zeolite can be rinsed slightly with ro/ri before use.

Zeolite 3 open 3 is used for system conversion, I don't think it is necessary to open 3 and 3 off. The current time of 4 weeks should also switch to continuous flow. Special attention needs to be paid to the reactor flow. This period is quite important and should not be too fast. In addition, activated carbon should be placed when there is a living being.

If you use live rock, the sponge power is added in the same way as zeo bak. Summary: kz base 4 balance zeolite amount & flow bak sponge power start3 morning / night skimmer adjustment more wet nutrients will be reduced, sump inside 2 xx I have no experience can not give you advice.

Remember that the current biology of tank is not very stable. Any dramatic change is a great pressure on corals. Let us build it all over time. In addition, you can add some functional algae bio-assisted and benefit from tank.

This is just my advice, I hope you still follow the advice of G.Alexander.

Hello Alex, something is going wrong, the high PO4 level is unusual and is the first thing you need to work on. Can you tell if you had high nutrients on this system since the beginning ?

As you setup the system have you cycled it with the 14 day method described over here:

http://zeovit.com/forums/showpost.ph...60&postcount=7

The bad smell of ZeoBac is normal and changes over the time so as long as there are no slimy patches in the bottle or any sediment the product should still be fine .

Please also post a good picture of your sump.

G.Alexander

Hi G. Alexander,

Thank you for your reply. I just recently found this website (wish I had found it a couple months ago) and the starting methods here are slightly different than others Ive read and there seem to make more sense. I started the tank cycle (no Zeovit) with Dr. Tims bacteria, no rock, only gravel and 2 marine pure bricks in the sump. Added an ammonia source and waited for the natural cycle (about 30 days). When the live rock came in I started the Zeovit system that day. Although I followed an old method I guess using zeobak, Zeofood, and zeostart. I followed the directions from the literature I got with the reactor. I did not add as much zeobak etc. as you have in step 8, and Ive never heard of or used sponge power before. Most of the other steps I did just like you have described. I stopped using the Zeofood for a couple weeks now and the diatoms and cyano are gone. As I explained before i wound up doing a start and stop because of the zeobak smell and not wanting to foul the tank. It was cloudy and there were grey things in it so I threw it away and started again. This took about a week to get in.

Im at the two week restart and 4 week mark if the zeolites. I will change out 90% of the zeolites today, do a water change, reduce my %of kalwasser in my ATO. And Ill follow the directions you provided. Ill post what the PO4 is a few hours after the change. I will get some sponge power (it will take a few days to come it)

Feeding is only 1 cube of frozen mysis shrimp daily and some nori algae every other day.

I am at a loss of what else to do. I have a GFO reactor I can put on to reduce the PO4 if you recommend it, even for short time.ive attached my sump.

The protein skimmer is in the first section of the sump followed by the Zeovit reactor. The carbon is on a shelf for passive flow threw it before the main pump.
Second picture shows the main pump, plumbing and electronics mounted outside of the tank stand.

Any advice would be greatly appreciated.

Thanks

Alex

Poor quality carbon has phosphorus problems and what kind of carbon you use. The kz system is usually in the sump. It only needs one skimmer. The rest can't be added. It even causes unnecessary conditional conflicts. For example: uv germicidal lamp Live sand. [ Feeding only 1 cubic meter of frozen prawn per day. Feeding some seaweed a day] This may also lead to high nutrient levels. In addition to the remaining uncertainties recommended by kz, try to remove them to reduce the uncertainty.

Zeolite bacteria Carbon source ->skimmer, I believe there will be good results, good things, tank time

I did a 30 gallon water change. Changed the 90% of the zeolite rocks. Added 3 drops of zeobak. .4 ml zeostart. I do not have sponge power but I have ordered it. I’ve increased skimmer to run wet. I’m using the recommended carbon and dose. It’s is a bag on a shelf before the main pump.

PO4 is at .36
NO3 is still around 30
KH is still high around 12. I’m changing the kalkwasser ATO to just RODI till it drops.

As shown in the sump pic I only have the skimmer and Zeovit reactor in the sump.

Thank you for the additional information and the pictures. The Alk level is much to high, I would recommend to let it slowly drop to 7.5 keeping it there as stabile as possible. The level should be in the range of 6.5 – 7.5. This will not cause any issues and is close to the natural level in the ocean.

As you ordered SpongePower it would additional be good t BioMate. It does have a positive effect to the PO4 level also. You can dose it @ 6 drops daily for 10 days, than the same quantity every other day if the Po4 level starts to decrease. BioMate is just a recommendation which will support the process, might speed up things a little bit.

ZeoFood does contain also nourishing elements for the corals. As long as nutrients are that high it is not necessary to feed to coral additional and you will experience what you already did, algae or cyanos or any kind of other film. It can be used late once if the system runs nutrient poor stabile.

I would not use PO4 absorbers at this stage, lets see what does happen with nutrients in the next couple of weeks.

NO3 is high also but basically this is not really a problem. The level will come down over the time.

If you still have the marine pure blocks running I would recommend to remove them step by step.

After the ZeoVit exchange continue dosing as follows:

ZeoBac – 3 drops daily for 10 days, than 3 drops 3 x weekly
ZeoStart – 0.3 ml 2 x daily
SpongePower – 3 drops daily for 2 weeks, than 3 drops every other day
BioMate – 6 drops daily for 10 days, than 6 drops every other day for some time

Run 0.75 liters ZeoVit with a flow of 80 US gallons per hour through the reactor continuous flow. Additional use 0.3 liters korallenzucht carbon passive flown in the sump.

It will take some time until nutrients are low stabile so you will need some patience. At the moment I would not add more fish.

Using kalkwasser is not optimal also:

http://zeovit.com/forums/showpost.ph...34&postcount=5

My recommendation is using a supplement for Alk and Ca which does not contain additional trace elements or a CaCO2 reactor.

Thank you for all the information. I have ordered the spong power and biomate. I will follow your dosing recommendation. I will switch over to 2 part once the dkh drops. I’ll continue weekly water changes until the parameters level out.

Thanks again,

Alex
