Hi this tank has been up for about 3 weeks now and i can't figure if this is diatom or rhizoclonium. My plant are growing fine but that because i spend several hrs each day cleaning the algae off the plants. My HC is getting destroy by the algae because everytime i clean the algae it pulls the HC off the substrate if i don't clean the HC the brown algae will completely smother them.
I dose about 5ppm nitrate, 5 ppm of potassium, and 3 ppm of phosphate every other day and 0.75ml of flourish when i don't does macro, Co2 lime green 4dkh drop checker. I dose high Phophate but I'm still getting some Green spotted algae which i don't really mind.

I did a 4 day black out last week and overdose with excel this algae didn't even budge. I did water change every 3 days with tap which has almost no trace of silicane. however I switch to ro/di last two weeks and reduce the fertilizer and this algae still doubling it growth each day, light only on 4 hrs a day. I might just let it grow as much it want this week than remove as much algae I can and do 50% water change

I've had some luck dosing H2O2. Killed it pretty quickly and my water looked like soda for a day. I'm not really sure if it'll come back yet, I'm still trying to remove all the death stuff from my driftwood.

Not sure why h2o2 killed it.
Anyway, I've used cups and cups of h2o2 in a 20 gallon before and never had ill effects other than some clouding.
I read on this forum about someone using it and then losing a fish, but the fish was old, and I don't believe it was related, although the owner certainly did.
If you're spot treating, be sure to turn of the filter.

Indeed diatoms.

Remove as much as you can manually while doing a 50% water change.

Add in 15 Amano Shrimp per 20 gallons and it will clear up over night. Do another water change, and you will be set.

okay i think i won the battle, turn out it rhizoclonium. I took some of the brown algae out of the tank and let it dry up. When it dry up it turn green so i assume it rhizoclonium. So i did a 50% water change and add 3ml of excel per gallon. The next day it turn green and most it melted away. I did another major water change 2 days later and dose another 3 ml of excel per gallon. The fish is okay including the chilli rosboras, otto catfish and fire red shrimp. I wouldn't overdose excel because of the shrimp but i been adding 1ml of excel to 5.5 every day so most of the fish/invertebrate was expose to excel before the overdose to allow them adjust to the excel.
