I have been doing regular water changes to reduce my alkalinity and it is now down to 7.5 over a period of about 2 weeks.

My nitrate is down to ~1.5ppm now. The GHA hasn't gone away and I may end up adding to my CUC to reduce it.

I am seeing excellent growth in my corals and some colors are improving. Polyp extension is excellent on pretty much everything. I am however observing a few corals paling out and I'm a bit concerned about this.

Current water parameters are:

pH: 8.27
Alkalinity: 7.5dKH
Salinity: 34.4ppt
ORP: 293
K: 410ppm
Nitrate: 1.5ppm
PO4: 0.00 per Hanna checker
Ca: 500ppm
Mg: 1365ppm
Temp: 77.6 F

Do you think the nitrates dropped too quickly? Or alkalinity dropped too quickly? Possibly this is the cause of some corals paling out? It isn't severe but it is quite noticeable.

Can you please post your actual dosing regimen and post a couple of actual coral pictures also a list of all korallenzucht products you already have ?

I will post coral pictures tomorrow.

My dosing schedule is as follows:

0.4ml zeostart3 twice daily

4 drops spongepower every 2 days

4 drops amino acids every 3 days

4 drops zeofood 1-2 times per week. I've held back on this to reduce algae and because until recently the nitrates were still pretty high.

I monitor potassium, iron and iodine and dose Red Sea colors components as needed which is extremely rare.

I also have a 1% automatic water change that occurs every day.

Here are some pics of the paled out pieces. The first one used to be deep red. The second one was darker. The last one is a red planet and it was super deep red before with no green. On one hand it has more color now that the green has appeared but the red is much paler than it was. Am I overreacting to the color changes?

Thank you for the dosing regimen and the pictures. Picture quality is not really good as they are very blue not showing the real coloration however you can try to dose products like XTra or CoralBooster, Iodine etc. to improve coloration.

Can you please post a list of the products you already have so I can suggest you a dosage for them ?

The only KZ products I have are the ones listed in the dosing regimen. Aside from that I have Red Sea coral colors A, B , C, & D which contain various elements.

I will check out CoralBooster and XTra. Any others you suggest? Also, do you have any recommendation about the GHA?

I would recommend to you add 4 ml XTra 3 x weekly to your dosing regimen in addition to three water changes each 15% within the next 10 days. This should usually improve coloration and growth. Because of the hair algae there is not much you can do. Would recommend to remove them manually as often as possible in conjunction with herbivore.

On a separate note, my nitrates are below 1ppm now. Alkalinity is stable at 7.5dkh.

I'm seeing color improvements on all except 3 corals which are still pale. Growth rate has simply exploded. Some of my corals are growing at close to 1/4" per day. I can literally see the difference in size of corals if I walk away and come back a few hours later. I didn't even know they could actually grow this fast.

XTra Standard, not the Special Version.

I have ordered the XTra and I am waiting for it to arrive.

Over the last week my nitrates dropped from about 1ppm to nearly undetectable and I am seeing some further paling of colors. I have stepped up the zeofood and aminos to try to prevent it from dropping to absolute 0. I also slowed the reactor flow slightly.

In spite of the extremely low nutrients the GHA continues to grow. Phosphate is undetectable using my hanna ULR phosphate colorimeter. Microalgae growth is very slow. Coral growth has also slowed.

I have ordered a red sea pro nitrate test kit to have the ability to test much lower levels accurately.

Obviously the zeo biology has really kicked in over the last week or so and my system is approaching ULN levels in a shorter time than I expected and possibly sooner than is ideal. I'd be interested in your opinions about these levels at roughly 8 weeks into the zeo conversion.

As for the GHA it has to be getting nutrients stored within the rocks and I really don't know what to do about that. I assume it will eventually exhaust what is contained in the rocks. The only alternative I can think of is replacing rock with clean, cured unused rock but that is just going to create an issue as that rock cycles and establishes a bacterial population. I added a Sea Hare but unfortunately it didn't survive for some reason (certainly not for lack of food). Does anyone have experience with replacing rock to remedy long term issues like this?

Looks like the algae do still pick up nutrients from the surface of the rocks. This is common when kalkwasser or PO4 absorbers where used on the same system before but over the time it should usually get better.

Regular removing them manually in conjunction with dosing CoralSnow can speed up that process.

XTra should usually improve coloration and growth of the corals but keep a close eye on the algae which should not increase their growth when you start dosing it regular.

Default Converting established tank to Zeovit

So I have been dosing the Xtra for about 2 weeks now and I have not seen any color improvements. My nitrate is now undetectable per the Red Sea pro nitrate test. The Nyos test still reads a near undetectable level. Phosphate remains undetectable per the Hanna checker.

I feed my corals with a distributed feeding of reef roids and coral frenzy every 1-2 days, at night when the polyps are most extended.

I can't complain about growth rate because everything is growing quickly. I have slowed the reactor to around 25-30 gph. I have stepped up the zeofood to 6 drops twice per week instead of 4. I haven't seen a significant algae growth increase but I still don't see color improvements in the paled out corals.

Trace elements I test for are iodine, potassium, and iron. All are ideal.

I am considering adding coral vitalizer to my regimen to see if I can improve the pale colors. Is there anything else you guys can recommend?

Reducing the flow is fine, just keep a eye on the nutrient concentrations while doing this. Also if you go back to the recommended flow again I recommend to do this in two steps within 10 days or so.

Have you already tried to do more water changes, for example three times 15 to 20% each within 10 days ?

I haven't tried large water changes, but I will give it a try.

Duly noted on the flow change.
