green hair algae

okay, 7 month in this hobby as biocube 29 user, uhm...for the first time im starting to get hair algae here and there for like 3 weeks now. I thought my clean up crew would handle that, but Im guessing they dont eat those.
What should I do to get rid of them? My bioload isnt heavy..i dont think.
I only have Filament Wrase in there, traded in my 2 chromis and $5 for that guy, last week. Anyway any suggestion on what I should do?

biocube 29
couple hermit crabs
3 turbo snail
1 astrea snail
2 nas snail
1 cleaner shrimp
1 filament wrase
1 dead artanic light bulb, only using the white one for now.
0 skimmer

My water is fine, except my Ph is kinda low, 6.7 or something. Could that be causing it? And if so what should i do to get it back to normal?

 

sorry..but "water is fine" doesn't cut it what are your ammonia, nitrite, nitrate, and phosphate readings?

 

Also, are you testing for alkalinity/calcium/magnesium? If not, get your water tested for those and post the results.

 

Also..6.7 is pretty low..If you have a biocube you probably have the hood on..is there any water surface agitation? If there isn't..your CO2 could be building up in the water and lowering the pH. Here is a good article that has everything you need to know about pH.

You may want to run a water sample out to the LFS... a pH of 6.7 is very, very low... I suspect that your ALK/Ca/Mg are all low as well.

Are you/have you been doing regular water changes, weekly/monthly? If not, get your water tested and consider a 5 - 10 % RO/DI-New Salt mixed water change.

 

+1 on all above

I think you meant to type 7.6 rather than 6.7 - as if its 6.7 I think you forgot to add salt?

a low PH will not help with algae issues
a low DHK will not help with algae issues
high phosphates will encourage algae
high nitrates will encourage algae
light of the wrong spectrum (old lamps or lamps where only part are working) can promote algae growth
elevated magnesium levels can help to reduce some algae issues.
use of a phosphate removing resin can reduce some algae issues
reduction and control of nitrates can reduce some algae issues

a low PH can be caused by either a low DKH - thus your tanks buffering capacity is reduced
it can also be caused due to elevated C02 levels in the tank - I note you have 0 skimmers so you may have an oxygen exchange issue

without knowing all the numbers in the equation, its difficult to ascertain exactly which of the above are the contributors to your algae issues.

ah okay, thanks steve good info. And others too ^^

 

Add a phosphate reactor and if you have stock lighting they are over due to be changed. Change one set wait 2 weeks or so then change the other set. The lights (losing their spectrum) is one of the main culprits for algae.

 

oh, yeah i guess i need to change the bulbs then. I ll start out by getting new arctanic blue light

 

I would change one 10,000k and one actinic. You want to get one of the weak 10,000k out of there.
