I can not really see it in the pictures, can you please describe the corals changes a little bit more detailed ? Also which kind of carbon do you use (quantity / active or passive flown). Lets temporary stop to dose BioMate, also how much ZeoStart do you dose 2 x daily ?

G.Alexander

[esco]

I have some brown green algea.
Which product may I have entered too much?
amino acid, vitalizer, sponge, biomate, iodine.
I have some bubbles and some cyano too

[jacky]

The picture is very blue and not very clear, can you give a picture with clearly visible signs. What is the dosage of Zeo Start, and those products you mentioned, what is their dosage/frequency.

[G.Alexander]

I agree with Jacky, please try to take another picture with natural day light. Does the film grow back if you vacuum the affected sand areas ? Please also post your full dosing regimen of everything you use in your system and the actual PO4 and NO3 levels.

How do you prepare your RO water, do you already use a purest water resin as the last stage of your RO unit ?

How do you prepare your RO water, I am using ro water with zero tds. do you already use a purest water resin as the last stage of your RO unit ? YES

The picture is really a bit blue, it is not very clear. Green algae, does it feel grainy and slimy to the touch. Unplugging it by hand, adding 1-2 sea urchins might also be good.

Temporarily change the dosage of Zeo Start to 0.4ml x2 every morning and night, the nutrition should not rise. As a result of the nutrient rise, I speculate that it may be a reduction in your tuned reactor flow, as the corals seem to be a bit TN. If the coral is currently in poor health, I also recommend that you temporarily stop changing the flow and keep the current flow, otherwise the coral will not like it repeatedly.

Temporarily stop aminoacid. aquaforest pot I don't know what it is, sorry. Coral tops seem to burn, please also cross-check results with different test kits (Kh/Ca/Mg)

[G.Alexander]

Can you please cross check, is your PO4 level 0.8 mg at the moment like mention in your last post ? That would be a really quick increase in a short time as it was 0.0 mg before.

G.Alexander

[esco]

I double check everything.
pO4 is 0.05 ( it was 0 before I stop to use coral snpw plus)
potassium 380
I raise flow 570 to 660 today
1.8 lt zeovit
0.8 x2 times start
cal 430 mag 1350 kh 6.8
8 drop x2 times week zeobak
1 lt carbon
thats all I am dosing like 2 weeks but I have still green algea
0 tds double checked

[G.Alexander]

Even in a nutrient poor environment algae do grow but I am still not sure which kind of algae it is. Can you please google for Bryopsis algae to compare the pictures with the algae you have ?

I would try to remove the algae regular manually with a brush plus adding two sea urchins to get rid of them. It might be a longer process so you might need some patience.

The water parameters and the dosing regimen is basically fine. Are your corals doing better again or do the still show a decrease in polyp expansion and slow growth ?

G.Alexander

[esco]

Yes looks like bryopsis.
colours are good, growth is fine but most of thembad polyp expansion.
zeobak the bottle is about to run out.It has no smell anything. Maybe , could it be dead?

[G.Alexander]

Glad to hear corals are doing better again. This kind of algae does also grow in a nutrient poor environment however slower than usual so the only way to get rid of them completely over the time is removing them manually regular and herbivore. You will need some patience as it might take some time.

The lost of smell with ZeoBac is not a indicator that the product has gone bad, it should still be fine as long as there are no slimy patches or particles in the bottle.

Is PO4 still 0.05 mg or does it increase ? Please keep a close eye on the level, with the increase of the reactor flow it should usually slowly come down again.

G.Alexander

[esco]

What about lights? I changed all bulbs 2x mh 250 w + 6x80w + ecotech 2x gen 6 at the same time before algea starts.

[G.Alexander]

A wrong spectrum in combination with nutrients can also be the cause of the increase of algae growth but I can not really help you with the LED setting. Make sure not to have to much red in the spectrum. To get rid of them manual removing in combination with herbivore should fix those issues. You can additional treat the algae with CoralSnow Standard by dosing it daily at the double quantity for some time. Just make sure not to use the Plus version for this case as it might cause PO4 swings if doses in higher quantities for a longer time.
