Default Reducing Phosphates

I have only been using the Zeovit system for a few months but my PO4 levels are slowly increasing (0.14ppm). What's the recommended way to reduce PO4?

I guess i either need to increase the ZeoStart and/or ZeoBak dosage or increase flow through Zeovit media reactor?

I have a 350L aquarium and currently dosing:

ZeoStart = 0.3ml twice a day (morning & evening)
Zeobak = 3 drops twice a week.
Zeofood = 3 drops every 2 days.
CoralSnow = 3ml twice a week.
Zeovit media = 800ml, change every 7 weeks
Active Carbon = 400ml, change every month
Water change = 10% every week

We can start with the reactor flow, use a small container to collect the water nozzle for 30 seconds, the volume x120, get the hourly flow

Do you have a sand bed? The system should take care of itself unless you are running a bare bottom.

Yes i have sand bed (crushed coral) but its only 1-2cm deep.
The flow through my reactor is around 200-300lph.

It looks good and the Zeo dosing plan is not bad.
If I understand it is right, if the coral is healthy, adjust the reactor flow slightly to 300L per hour.
It's hard to say why PO4 is slowly rising.
I cite these possibilities:
1. Source water
2. Some cornerstone materials are leached
3. What kind of kh ca is added?
4. Some filter leaching
5. Some mechanical filtration
6. What kind of cornerstone and what kind of sand?

If you are willing to get Zeo SpongPower3 drops every other day. ZeoFood retains the use of corals afterwards. Try to drop ZeoBac and ZeoStart before the reactor inlet, pull it down several times a day. Skimmer adjusts the humidity and simultaneously vacuums the sand when performing water changes

A more balanced spectrum seems to help with nutritional improvements.

Can you post more pictures about the main display system and Sump?

How often or do you ever vacum your sand bed. Crushed coral tends to trap food particles .
Or it could be you have too many fish in the tank.

Reactor flow seems to be to low. Can you please measure the flow by collecting the water from the reactor outlet for 30 seconds with a small container ? If you multiply the volume of the collected water with 120 you will get the exact output per hour.

I've measured the flow through the reactor as per your instructions and it works out at 200lph. How many lph would you recommend? The aquarium is around 300L after taking rock and equipment into consideration.

My po4 is currently 0.20ppm and my nitrates is 10ppm.

I vacum the sand bed one a month and i have 7 fairly small fish. I usually feed twice a day, a little dab of Masstick in the morning and cube of frozen Mysis or Byne in the evening. Is this too much?

A little thought, maybe when using frozen foods, use Ro/di water to rinse them slightly, or try to change them once a day. How do you feel? If the product is nutritious, this can help reduce nutrition. But the Zeo system is very powerful in reducing nutrition.

First of all, don't know if you have completed the "first replacement of ZeoVit material"?

If the "first ZeoVit material replacement" has been performed and the coral is healthy. 300L water = reactor flow rate is approximately 300 liters per hour. (Small container collects water from the reactor outlet for 30 seconds to measure flow? If you multiply the amount of water collected by 120, you will get an accurate hourly output.)

The amount of flow per hour in the reactor seems to help with the reduction in nutrients.

ZeoStart = 0.3ml twice daily (morning and evening)
Zeobak = 3 drops, 3 times a week.
Zeo SpongePower = 3 drops every other day
Coral snow = 3 ml twice a week.
Change water every week = 10%

If you prefer, we can try to pull the reactor twice in the morning and evening, then drop the Zeo Bac and Zeo Start into the reactor inlet. skimmer adjusts the wet. When you change the water every week, vacuum the sand at the same time.

1. Execute Zeo Basic 4 products
2. If the coral is healthy, get/adjust the correct reactor hourly flow
3. Vacuum the sand bed, adjust the skimmer equipment, reduce feeding

Hold on for a while and try to see if it helps

Since the system has been in operation for several months, usually the nitrate should be “not detected”, then, [reactor hourly flow] and [Zeo basic 4 product], we can make this part “confirmed”

Then, in the raw water part, is the last passage with resin material as the overfill?

Ok I increased the flow through the reactor to 300lph. It's been running constantly at 300lph for a week now.
I have also stopped dosing ZeoFood for now. I guess this isnt required while my nutrients are this high.
I have been wet skimming for a few weeks now.
My NO3 has lowered to <5ppm.
Unfortunately my PO4 seems to be slowly increasing, its now 0.26ppm!
My tank, rock and sand bed looks great, no algae or film at all. I havent needed to use my glass scraper/cleaner for a week.
My SPS also seems to be ok but my lps isnt doing great.
I've ordered some sponge power but it hasnt arrived yet.
Should it matter i am roughly 4 months into using Zeovit. I replaced the Zeovit media/stones (800ml) for the second time two weeks ago.

Can you post a picture of your sump and the tank ? Also how many fish do you keep and what are their sizes ?

I've performed a couple of 10% water changes and siphoned my sand bed. My PO4 levels have come down a little to 0.18ppm.

Am i correct in thinking the ideal target for PO4 is 0.03ppm and NO3 5ppm? Does running low nutrient levels like these encourage cyano, dinos and other algae problems?

I think, in Sump, the bubbles on the water generated by Skimmer, the bubbles don't seem to be easy to soak, which means the water quality seems to be "fertile", maybe for some reason

Thank you for the picture but I can not see anything problematic. What about the fish ?
