Default Converting established tank to Zeovit

I am noticing some of my blue corals and purple corals turning green. Acros and montis alike.

Iron is quite low according to my Red Sea iron test kit, which in my opinion suggests a very high iron level of 0.15ppm is normal and it clearly isn't.

Sadly the GHA is still not being affected by the now undetectable nitrate and phosphate after weeks of these low levels. Obviously it is leaching from the rock which doesn't surprise me. This rock came from a previous system that was fish only and had 40-80 ppm nitrate for some time. I have ordered two Sea Hares and added a foxface lo to help with this issue.

On a separate issue, I am struggling to keep the alkalinity stable because the alk usage keeps increasing while calcium is barely being used.

I am dosing 17.5ml of b-ionic alk supplement per day while only dosing 6ml of calcium. I am new to dosing 2 part in this manner as I've always used kalkwasser or dosed 2 part manually without putting too much thought into dosage amounts. Does this seem abnormally out of balance?

Sorry can not help you with the two part dosing maybe someone else can tell you more about it.

Forget the iron test the element is difficult to detect especially in saltwater. Just keep dosing it depending to the look of the corals but as long as you have green hair algae stop dosing it completely.

I'm having some STN now. Haven't really changed anything.

Can you please check the potassium level and the flow through your Zeovit reactor if it is to high ?

Flow is slow. Maybe 30gph. K is at 410.

I expect Ca and KH are stabile within the recommended levels ? Is this the only coral affected ? Are the other corals growing well ?

Ca and KH are stable. Ca is at 450 and KH is at 7.3dKH.

There are 3 corals affected in total, this is the worst. Growth has slowed to nothing. The only change in parameters is that nitrate has become undetectable on both of my low range tests. I've tried to increase feeding to get a little nitrate back into the system which has improved polyp extension at least. The green birdsnest in the photo is almost completely gone now.

I have also skipped the zeobak doses for this week to try to prevent the nutrient stripping.

Difficult to say what has caused the TN but it is often a imbalance of elements. Firth think I would try are three water changes each 15- 20 % within 10 days.

Have you changed anything else, which kind of carbon do you use ?

I've been using the KZ carbon per the recommendation. I decided to remove the carbon since it was due to be changed. I removed it for a week and saw improvements in colors and overall health. I have since put it back at half the suggested quantity and have already seen some issues start to come back. I am thinking of reducing it even further.

I have reduced the zeobak doses to half the regular amount to some positive effect. I am able to maintain very low, near undetectable nitrate this way which seems to significantly improve color.

I also did a deep cleaning of the sand and rocks to try to remove any stored phosphate to help remedy the hair algae problem, which isn't gone but has improved.


Full tank pic below. I seriously need to re-aquascape this mess. I have sort of gone a bit overboard with the acros. You can see the hair algae that remains and a couple of pieces that are still on the mend from my previous (pre-zeo) nutrient problem.

If you are able to keep nutrients under control with the lower dosage it would be fine. Also if the lower amount of carbon works well you can reduce it.

I've been reviewing the dosing regimen of others and I see quite a few people using xtra but they only seem to dose it 2-3 times per week rather than daily. Is it possible to overdose xtra to a negative result (other than algae)? I clean my glass every 3-5 days, it varies from time to time.

If overdosed you might experience some kind of a algae film and darker coral tissue. I have dosed it usually 2 – 3 x weekly depending to the corals coloration.

Default Converting established tank to Zeovit

I reduced my Xtra dosing to half the original amount and have seen an improvement in coral color.


I finally identified the algae in my tank as bryopsis. I am going to use the fluconazole method to eradicate it. I will manually remove most of it and then dose the fluconazole afterwards to prevent any artificial nutrient spikes as the algae dies. I have only found a couple of people who have done this on a zeovit system and no one seems to have had any issues as a result.

Has anyone here tried this method?

The fluconazole completely eliminated the bryopsis. But now the GHA just has more room. I cant take this anymore. This tank is growing algae like I am pouring lawn fertilizer into it. My dosing hasnt changed except I recently added bio-mate to the regimen. Everything has been stable and nutrients are unmeasurable. I barely feed the tank at all and havent for weeks trying to get rid of this crap.

I have been I this hobby for 25 years. I have eliminated GHA many times. This time I simply cannot get rid of it no matter what I do. If I cant get this under control Im taking this tank down and calling it quits for a while. This is infuriating. Please help me!!!
