Thanks a lot for helping me with my journey into the marine aquarium world.

Lately though i have been having this algae problem. It only shows up when i use flash in my phone. But under sunlight (normal photo). You can harldly see it. So i mistook it for fungus growing on my rock.




water parameters are:

1. KH carbonate hardness (dKH) --- 7
2. pH Acidity --- 8,2
3. NH4 Ammonium (mg/l) --- <0,05
4. NO2 Nitrite (mg/l) --- <0,01
5. NO3 Nitrate (mg/l) --- <0,05
6. PO4 Phosphate (mg/l) --- < 0,02
7. Density -- 1.023

Inhabitants:

1. 3 --- green zoanthids. I feed them the white stuff from thawed prawns.In the hope of increasing growth.


Plz help!

Your tank looks really new...this is a normal.

In your post you say "œ under sunlight"
Sunlight is the virtually the worst light.
Even small amounts regularly will cause tons of algae.

 

[giga84]

i don't use sunlight. I should have metioned the equipment list from the previous post

Tank specification:

1. volume = 32.5 liters
2. Lighting = 24 w 12000k - 15000k (sunsun ADS-300h)
3. Filteration:
a. sponge
b. activated carbon 100gm
c. Bacteria growing Bio-ball (Fm908) 500gm
d. Dead coral rock (about 1.5 kg to 2.0kg)
4. Protein skimmer - skimz SH1 (L88xD85XH388 mm) with pinwheel pump rated for 200L
5. Lighting schedule 8.00am to 6.00pm (10hrs) (by automatic timer)

i also have 20gm of granulated ferric oxide. And my tank is an old one. I just changed the water(100%) and also cleaned the tank.

As your tank matures, the algae will come and go, eventually balancing itself out. I read your previous post. Looks like the next type of algae is taking hold. Just let a clean up crew do your work for you. It too will eventually go away. I had dinos, then green Cyano and now I’m on the backside of a bad turf algae outbreak. With having started your tank without sand (look like you may have added some) it’ll take that much longer for your tank to balance itself out. Just keep up with the water changes. Do you still have your fish and clean-up crew? You will need something alive in your tank besides a few zoas to keep your tank moving along in its maturation.

32.5 liters = 8.5 gallon fish bowl.

How old exactly is your tank? It looks pretty new to me not mature, takes at least a yr. for a mature stable tank unless you run a LOT of additional equipment To counteract the ever changing stability issues as the biodiversity evolves. I see no Coralline encrusting algae that is associated with a stable mature tank either, unless by some miracle it has not been introduced to the tank yet. A 100% water change can be brutal on a mature sys. as well, better done at 5 to 10% a week at same parameters as the existing water. Id avoid doing that again unless its an emergency. You need more in the tank then Zoos, toss in a hardy fish to get the good Nitrifying bacteria cycle going strong or add a drop or two of pure ammonia per gallon to establish food for the bacteria & do it the fishless way just test & be sure the ammonia stays at or below 2ppm since you have some livestock in tank. Any readings at all of Nitrite means the tank is still cycling. Dr Tim's Ammonium Chloride is a good product for this also. Patience is your best ally read all you can about everything as the tank matures, the info is endless..............................

Phosphate will leach out of your rock and sand for a while. If it goes on and on, there are other fixes, but for right now, you're not that bad.

 

[rocklobster1]

Some good grazers like turbos and tangs will do the trick.

I would never change 100% of the water at one time. In a true emergency a big water change is fine but I would not recommend changing it all at once it can cause you other problems but i would agree with the other post that your tank looks new, i dont see coralline or some of the other things and if its new or a just cleaned up old tank it should clear up in time with good husbandry.

 

[j.falk]

I would never change 100% of the water at one time.

It looks like he probably had a tank crash judging from what livestock he had in the tank last October (see the link he provided) compared to now. 100% water change is definitely recommended if a tank bombs out.
