What causes these Spirogyra in my tank?




So. Since day 3, I had small troubles with Spiro as it began to appear on my HC. Now, 2 months later, I still have this problem even (much more intense on my Java moss) if I tried fixing the problem with different solutions:

-Frequent large water changes (50%, weekly)
-One-two punches (Excel and H2O2)
-Hand removal
-Increased flow
-Lift my light 4 inches higher (thinking I had too much light)
-Added some Amano Shrimps (they won't even touch the Spiro)

Nothing helps. I am now at the point where I will buy some Algaefix to erradicate this type of algae, but I am afraid it will come back if I don't treat the cause.

Here is my setup:
ADA 60p
ADA Aquasoil
Finnez Ray2
Pressurized Co2 (2bps)
Eheim 2217
Small powerhead
PPS Pro ferts
8 hours light / day

Planted with DHG, HC and Java Moss.

Amonia and Nitrates are at 0.
No idea about phosphate levels.

Seriously, why the h**l do this kind of algae keeps on coming?
Please help!

Try switching to EI dosing perhaps?

Go with the algaefix. It's the only way I've been able to kill spriogyra that's been growing in my mosses. Remove any shrimp from your tank before dosing.

What's your tank size? What kind of filter do you have?

Yep, go ahead with algae fix to get rid of the algae. Secondly, reduce your photo period to 6 hrs.

Guys I've tried algae fix in my high tech tank. It didn't even dent the spyro for me. Did nothing for the bba as well. I've done the same one two punch. Algae fix. Max co2 for a day without gassing fish. Excel treatments. Nada in results of killing the algae. I have however found balance between my dosing ferts lighting and co2 which has prevented it from all out annihilation of my tank.

It appears to be a micronutrient deficiency of some sort. Once micros are added, spiro diminishes greatly, at least in my tank. I was able to get rid of spiro by removing as much as possible, then adding CSM+B regularly. It's completely gone now.

Thanks all for the advices.

I will be trying AlgaeFix for sure, but if the root cause is not fixed, I suppose it will come back!

I do dose micros with PPS-PRO method (2ml/2days) . Should I dose a little more?

Won't my HC suffer from lack of light?

Im only recommending EI dosing because there could be an imbalance in your ferts you're unaware of. I've never dosed pps though so im sure you have a better idea of what you're doing there. When I switched to EI dosing all my algae issues disappeared

I will keep that in mind, but I will keep that as a last resort method since I really like the simplicity of PPS-Pro Thanks!

The tank is very sparsely planted, you have way too much light, and probably not enough CO2.
