Based on the pictures I'd say you're dealing with algae-blooms. To have that amount of algae growing in such a short time is interesting. Phosphates are way too high.

Start with the basics:

Don't overdose, especially not ZeoStart (could be your culprit)
Check flow through the reactor. (measure it, should be 125gph, or 500L/h)

Until you've gotten the algae under control: Stop dosing anything but Zeostart, zeobak and spongepower. The rest aren't needed until the system is running nutrient "starved".
Make sure you use carbon, you should use 500ml if you have it in a bag in the sump.

I'd still use Coral snow though. 2 times weekly, 10ml per dose.

Keep an eye on phosphates, measure it every other day. Nitrates aren't in a level where they're a problem as of now.

I will measure the flow by filling a 5 gallon bucket and do the math. Should I start with new zeolite rocks and new carbon?
Would that get me closer to zero in terms of phosphates?

So basically I am going to do the following,
1ml of zeostart daily.
6 drops a day of sponge power
6 drops every other day of zeobak,
2 times a week 10ml of coral snow.

Is that correct?

Thanks for you help!

Unless it's time to change zeolites and carbon, I don't think you need to replace them ahead of time.

Yes, that dosing schedule looks correct for your stated water volume

Happy to help

Hello Daniel, my recommendation is to remove the Walmart material completely as you will not need it and you can never be sure what is leached out of it in saltwater.

Continue dosing as follows for a net water volume of 500 liters:

ZeoBac – 5 drops 2 x weekly
ZeoStart – 0.5 ml 2 x daily
SpongePower – 5 drops every other day

To improve the cloudiness you can dose 10 ml CoralSnow 2 x weekly additional.

Stop dosing CoralVitalizer, XTra and LPSAmino at the moment completely.

Also run 1.25 liters Zeovit with a constant water flow of 500 liters per hour through the reactor. Place 0.5 liters activated carbon passively flown in the sump.

Personally I would also remove the marine pure blocks.

G.Alexander

After looking into all possible issues I found the issue....huge newbie mistake, my DI resin was used up. I was getting 210 ppm tds out of my rodi system. I have done at least 2 30 gallon water changes on my 175 gallon system in the last 2 week.

I have taken out the marine pure.

I want to do a 80 gallon water change on my 175 gallon system (including sump)
replace the zeolite stones and carbon because they're due to change in 1 week.

I want to put in some left over cabirsea fake rock ( never used, left over from my build) to replace the marine pure in my sump

What should I do?

Above sound safe?

What about dosing?

Thanks!

I have done 2 - 3 (30 gallon) water changes with the crappy water.

After changing the di resin Im at 2ppm on tds meter. The reason is I don't have a tds meter on the rodi unit. I bought a pen tester

Its hard to get a good reading with a pen tester because the cup can leave residue charges .
I'm assuming that it is testing higher then it actually is. If that helps

I am very happy that you have found the problem. This is a good thing. If I understand your problem, cabirsea fake rock soaked Ro water to replace the water several times until the PO4 is not detected. If you are willing to use the bag to pack some KZ activated carbon, and a small build pump, I believe it is also a good method.

The difference in volumetric water between the two is complemented by seawater.

So I will change out the zeolite and carbon. Do a 70-75 gallon water change.
How about dosing start, bak and sponge power?

If I understand your problem, the amount of water is 500L. Is this your first time to replace the zeolite? If it is - retain 10% of the old 90%, Zeo Bac5 drops x 10 days, two weeks later if the coral is healthy, switch the zeolite continuous flow Zeovit, a constant flow of 500 liters per hour through the reactor.

If this is not the first time to replace the zeolite - replace 50%, keep the old 50%, Zeo Bac 5 drops daily, do 10 days. If the coral is healthy, switch 500 liters of constant water per hour through the reactor

That is, Zeo Bac - 5 drops x 10 days
Zeo Start3 - 0.5 ml per day 2 times
Zeo Sponge Power - 5 drops every other day

10 days later, Zeo Bac - 5 drops, 2 times a week
Zeo Start3 - 0.5 ml per day 2 times
Zeo Sponge Power - 5 drops every other day

Kz activated carbon is 0.5-1 liter per 1000 liters. Replacement intervals are 30 days. Use the bag to passively put the sump. If you prefer, soak them with hot Ro water to speed up the cleaning process and make more carbon.

If I understand correctly, 500L water, 70~75 US gallons is about 260~280L. I think there is too much water change, give them time. As long as you do the dose, skimmer is more wet, Zeo Snow, I believe it is not a problem.

My reason is that the tank is not very stable, only need 10% WC per week, siphon vacuum sand, and the method mentioned above, the situation will improve

The light part, suitable white light can help this process.

Total volume is 650L
I have changed the zeolite twice before. This will be my third time changing the rocks.
Fourth time changing kz carbon.

I haven't changed the media just yet.

I did a 40 gallon water change this morning.

I want to change out the media later today or tomorrow morning.
Should I do another 30 gallon water change?

And sorry to ask this again, but based what should I do next?

Thanks!

What does media mean, zeolite?

I understand what you mean, referring to the Ro filter channel.



If I understand what you mean, then you can do this - change the media and then confirm that it is good TDS, SI, PO4. 30 US gallons for water change I think there is no problem, make sure that the water quality difference between the two sides is not too much. I think "the real need is to stabilize the tank as soon as possible"

In addition, when Zeo zeolite and Zeo activated carbon are replaced at the same time, it is recommended to wait for one week, not the same time. May be more suitable. Zeo zeolite can be made first.

@What should I do next? As mentioned above, the amount of water, Zeo Bac1 drops = 100L = 25 US gallons, for 10 days. Detail #25

Can you tell me what is your next step after you replace Zeo Zeolite (6~7 weeks)?

Unhappy

Thanks for the reply,

Zeolite is the stones that run in the reactor. The kz branded stones, sorry if that's not the correct name.

Let me explain where I am at today.
I have a redsea 650 L mixed reef tank
50-80 lbs of caribsea life rock (it's a dry rock that you can buy at the store that has a purple colour, not wet, sold dry)
My tank has been running for a total of 6 months.
Running KZ for 5 months.

The main issue is phosphates to high
3 ppm
Sps are brown and LPS are okay
Glass and water are always dirty.

I did a 30 gallon water change Thursday morning which is done Evey week
(I do 30 gallons every week)

Today I did a 50 gallon water change in the early morning because I am frustrated at always looking a cloudy water and dirty glass.

In the after noon no change, needed to clean the glass because it was dirty (brown slim) and cloudy water.

I am doing what everyone on this forum has recommended.
1ml of KZ start
5ml of bak 2 times a week
Sponge power

Nothing else.

My tank does not look a thing like the beautiful KZ tanks that are online.

I did not change the zeolite (KZ branded white rocks)
I did not change the carbon
The KZ rocks and carbon have not been changed for 6 weeks.

I am so frustrated and don't know what to do next.

I hope above explains what I am going through.

Do I do another water change?

I am at the point I want to do a 100percent water change and start over.

Should I do that?

Again I want to say to everyone thanks for helping.

Looking forward to your experienced advise!
