GHA Is coming ...... :(

xiholdtruex · Jun 7, 2019

Hello everyone, Last time I posted in depth I was having a issue with cyano , rip cleaned tank and rinsed sand and took care of that issue, 10 months later not I am starting to having a new menace Green Hair algae. It is starting to grow on my rock and some frag plugs. I have grabbed the two frag plugs it was on and peroxide dip and it eliminated the GHA on the plugs. Now I have a frog spawn with three small heads and it seems to be growing in the middle of them. tried removal and it came back. Is frog spawn ok to peroxide dip? I am going to rip my tank apart soon and clean out the sand I know under the rocks it is teaming with detritus. I removed one to scrub and a cloud of baddies came out in the tank.

Thanks in advance

my go to strategy for green hair algae, is two fold:
1) raised magnesium via kent's tech m 1800+ ppt sustained for a few months.
2) increase nutrient export (bigger skimmer, more macro algae, more mechanical/sock filtration)

if it is hair algae it will disappear over time and be skimmed out. Not sure of a good clean up critter that will keep it under control.

I have GHA on my frogspawn. I upped the housekeeping on the tank with regular rock detritus cleaning using a turkey baster, controlling nitrate and phosphate with NoPox, added a refugium, etc. The last stubborn toehold the GHA has is the frogspawn. I didn't want to risk hydrogen peroxide so I have only been doing physical removal via toothbrush. It is slowly yielding and reducing its growth but it is slow

If you can get the frogspawn out of the tank and do a better job with a toothbrush it should be better than what I have been doing
