Controlling GHA on Fissidens

[Rob Dahl]

Here are my specs:
TANK–30li.Fluval Flora
LIGHT– 13w, 6400k, CFL
Flexi mini, PAR 230 @ 5cm., 40@ 50cm.
CO2–pressurized soda jets and ceramic diffuser 1bubble/sec.
FILTRATION–Fluval U1, 250li./hr.
FERTILZATION–Excel–3ml./day
FluorinK–3ml./every other day
Fluorin GRO (nitrogen)–3ml./day
I have tried the shock treatment with 5ml. Excel/twice a week, and 2hr. interrupted light at mid day. Would like to get some help on this.
Many Thanks,
Rob

Forgot to mention R/O water changes once a week.

Hi Rob
Can you identify the hair algae from this link......>http://www.theplantedtank.co.uk/algae.htm

Try twirling a tooth brush around in it. Not sure how well it will work in the moss but worth a go

Hi group,
Have used the tooth brush with some success. I think there is a combination of some different algaes. There seem to be algaes with different characteristics. It's just that they seem to be intertangled in the Fissidens. So you can't disentangle them.

Keep at it with a toothbrush, if it's possible to get the whole piece of Fissidens out (if it's tight to a stone or wood) you could put it in a small container and give it a total black out, if that's not possible maybe try to cover the moss with some Catapa leaves or some black plastic for a few days (make sure that the plastic is non toxic) tighten some stones on the corners of the plastic or pieces of lead.

Thank you Martin and Hoggie. Today is water change day, so I will see what pieces I can remove for treatment. (and keep at it with the toothbrush).

Fluval Flora

and Here's my dry start SpecV at 32 days

About the ferts, I see fluorinK (only potassium?) And fluorin gro (only nitrogen?). Google doesn't know them but if this is true you are missing phosphate and traces. In that case you can twirl your toothbrush every day, but it will grow back unless you add the missing nutrients.

Thank you for the information Johan

Any update on this?

Hi Johan,
Yes, I've been daily dosing Excel and using a test tube brush to daily "comb" the GHA. GHA now almost eliminated from the Flora tank and slowly retreating in the SpecV.
