Aquarium Advice Addict
Hi all
Seems like I'm working my way through the algaes!
First, I had cyano bacteria and GSA. With the suggestions on this thread here http://www.aquariumadvice.com/forums/f24/before-after-103131.html I have now been three weeks and I have had no more cyanobacteria grow (yay! thanks guys!). The GSA has returned a bit after my scouring the tank but in much smaller amounts.
But it looks like I've now created an environment that attracts BBA! Asmallamount of black furry yukness appeared around a week or so ago on the glass at the back and ths week, more has appeared on one of my driftwood pieces.
Current params.
Amm & NitrITE = 0
PH < 6.0 (I can't measure any lower)
NitrATE 40ppm
Phosphate = 3ppm
Dosing routine: 3 weeks ago I changed my routine (see above thread as to why). It is now as follows:
Potassium Suphate - 20ppm.
Potassium Nitrate - 10ppm - I'm aiming to have a nitrATE level of 20ppm post-PWC. Being a 15g tank, it goes up over the week to usually somewhere around 40ppm when I do the next change.
Potassium Phosphate - 5:1 ratio of Nitrate to Phosphate.
Plus I dose 1ml flourish excel comprehensive.
I do all my dosing weekly when I do the obligatory 30% pwc.
I don't inject CO2 as it's a low-light setup. I was doing some reading and I read that to prevent BBA, you should aim to keep around 15ppm NitrATE and 0.5ppm phosphates. I can do that, but this is the conditions I had before. In other words, this is the environment that appeared to be the cause of the cyano & GSA to thrive.
I scrub the BBA, but just like the cyano/GSA, I need to address the underlying cause to prevent it returning.
HELP! any ideas?
