BGA return, what next
(SLEngst) wrote in message ...
I had forms of BGA show up in 3 planted tanks. I treated all three for 5 days
with the 1/2 dose of maracyn needed for fish fungus or whatever, as suggested
in an article in the KRIB. It came back in two tanks. I treated them both for
7 days with full doses of maracyn. A week later it now seems to be reappearing
in one of those two tanks. First clue is - even my prefilter media is starting
to "pearl", as are above substrate roots, etc.
Do I do some huge water changes, again? and go for 10 days on the maracyn? I
just did a virtual 90% water change on that tank less than a week ago. How
much of this (maracyn) can the fish take?
Thanks in advance,
Sharon Engstrom
A better more effective way:
Blackout the tank by covering it completely with towels/blankets/trach
bags etc.
This works in 3 days, not 5.
Oh, BTW, did I tell you it's _free_?
This will kill the BGA.
You should remove as much algae as you can prior, do a 50% water
change, turn off the CO2, add KNO3 to the tank as per Chuck Gadd's
dosing calculator to 5-10ppm NO3, cover the tank for 3 days.
Remove after 3 days, vacuum up any leftover detritus, 50% water change
, turn CO2 back on, dose the tank again with KNO3, K2SO4, PO4, traces
and keep up on dosing and taking care of your plant's needs from then
on.
BGA is pretty easy to deal with, BBA, GW are tougher.
Unless you address the causes of algae, poor plant growth, you will
continue to get algae. Feed your plants.
BGA floats in the air and recolonizes soil after volcanic
eruptions/intense fire in about 20-30 day's time. It'll come back
unless you correct the conditions.
