I'm trying to cycle my new planted tank. In the early going, my pressurized CO2 was down for a week, and during that time the algae went crazy:eek:

I'm not sure if this was due to lower CO2 levels, or if my tank went thru a "silent cycle"? I've had some cycling fish in there for 3 weeks & still no nitrites/nitrates, that's another story:icon_ques

While doing a water change last night, the algae was so bad I decided to remove most of my plants and do a hydrogen peroxide dip. Did ~33% water change with RO water, and now not sure what to do? Mst of my plants are in tubs. I am keeping my lights to 7 hrs/day, doing water changes 1-2 times per week, and can't imagine Phosphates are a problem since I mix lots of RO with my well water.

Not sure what my next action should be as I don't want to go back to where I was last night (see before & after pics).

I appreciate any suggestions :help:

Looks like hair algea to me. What type of lighting, and do you have it sitting on top of the tank, if so raise your lights that should help.

I just had a similiar problem with thread/hair algae. I peroxided my whole tank per the one two punch method. Then started using flourish exel to help kill the algae off. It has made a world of difference. I cut my light period to 8hrs, upped my co2 and obviously started dosing flourish excel. within a week i have seen a difference in the quality of the tank. I did go into a mini cycle but at this point I dont care. The algae was taking over. Dark cobra is the one who did the write up on the one two punch method.

Hi starfire,

I have theMarineland 24" Aquatic Plant LED
http://www.marineland.com/Products/...led-aquarium-lighting-for-aquatic-plants.aspx
It's a 26 Bow so it's a fairly deep tank @ 20". I started out with a daylight cycle that was probably too long, so I've scaled it back to 7 hrs.
Based on the specs and input from others, I thought I was medium light, but maybe I'm pushing into high?

Thanks…I read Dark Cobra's thread also and was intrigued.

I am not sure if my tank has cycled (I'm thinking "no"). I'll have to find that thread again as my only concern would be setting back my BB. I currently do not use excel as I have CO2. Not sure how effective just the H2O2 would be?

I plan on dip-peroxiding the rest of my plants today, and doing another sizable wc.

Hi Raymond,

26 Gal (20" tall), running Marineland Aquatic Plant LED (link in post below) for 7 hrs/day. I was ~9hrs/day initially & when this issue popped up. Have EcoComplete substrate, dosing Flourish Comprehensive, and dosed Florin Axis during the 10 days or so my CO2 was down.

Thank you...
