I don’t know how to beat this algae, posting a few pictures if anyone you can help. Looks like some sort of light to medium green hair algae that is stringy and smells too, when I use a brush most of it comes off but not completely, part of it sticks to the leaves. It gets to about 5 to 6 inches at times. Once removed, it grows back within a few hours. I have tried black out for 3 days, I have tried double dose of Excel. I pulled out most of the plants, vacuumed the gravel, and changed 90% of the water. Replanted some of the old unaffected plants, and added new ones, but it has come back again. Here are my tank stats:
KH 4.7 83 ppm (raised using bicarbonate)
PH 6.4 (fish gasping at 6.3)
CO2 pressurized with controller. External inline Rex reactor.
Dosing EI, cycling every 9 days, with 3 days off.
Filter: Ehiem Pro-II 2028 and 2026
- 38w x 2 6,500K Narva (German – Labeled Oceanic Nature, for plants also)
- 36w x 4 9,500K (Arcadia – Labeled HO marine lamp)
- 36w x 2 Osram Fluora Grow (36W/77 pink light)
1st, 4th, 7th day:
KNO3 ¾ Tea spoon
KH2PO4 ¾ Tea spoon (if I dose less I get green dust) Sometimes 1 Tea spoon.
MgSO4*7H2O 1.5 Table Spoon
2nd, 5th, 8th day:
CSM 30 ML – 1table spoon/250Ml solution - (was dosing TMG 3 times 15ML before)
3rd, 6th, 9th days off
10th day 50% water change.
CO2 is a good 56 ppm, plants are pearling really well and look healthy. As you can see in the photo, I have enough plants. The foreground is still not covered. I have pigmy chain sword and tenellus.
Fishes are mostly tetras, thread fin rainbows, ottos. Not over crowed.
One thing I suspect after trying everything, is the lights. The Arcadia is labeled as HO marine Lamp, this could be causing the problem. It is due for a change and I am going to use 6,500K HO arcadia or Zoo Med 7,000k, depending on what is available.
What algae is this and how can I beat it? Should I just keep harassing it and wait for the plants to grow some more? Or can this algae be beaten somehow by increasing or decreasing something?
Appreciate any help.
