Guilt Tank (continued)
#1
'Guilt' is how this tank was referenced in Another Place.

The impetus for posting this thread comes from WingNut, who began a course of Easy Life's AlgExit in his tank(s) to operate on his green algae. I mentioned in his thread that I'd begun playing with the same product and, though requested to report back there on progress, I felt it better to create a new one.

The reason for my use of AlgExit is a bit of an experiment to see if it'll work in 'Guilt', which has an impressive display of Black Beard Algae (BBA) which I actually quite like since it seems to concentrate its efforts in one area of the tank and looks 'natural'.  

In theory AlgExit might work. Although BBA is theoretically 'red' algae it's actually green and various users report that it deals with BBA successfully. Contrary to that is my supposition that its active ingredient is lanthanum chloride, LaCl3, which works by binding phosphate to calcium - thus rendering it unavailable to algae.  Presumably it renders it unavailable to higher plants, too, but (again presumably!) algae must keel over from phosphate deficiency before plants are affected too much, if at all.

Trouble is, there's little or no calcium in Guilt's water column and therefore there's little or nothing of use to LaCl3 in context! It's a blackwater(ish) tank and vital statistics are currently :

Temp 25.6C
GH <1
KH <1
pH 5.74
Conductivity 53.2uS
TDS 37.4
Photoperiod 7hrs
Plants : mainly Cryptocorynes and floating Salvinia.


I'm halfway through the recommended AlgExit course, having given the third dose yesterday. As yet there's no discernible change in the BBA.

I took a quick (5mins) video last night - mainly to illustrate the BBA but also to show what's happening in Guilt generally and in doing so distract the viewer from the scratches on this rather long-in-the-tooth tank:



(Most residents appear at some point but both Chocolate Gouramis and Kuhli loaches elected not to).


My expectation is that the AlgExit won't work even after extending the course beyond four weeks. Thereafter my plan is to introduce some calcium (I think I've got calcium chloride and calcium nitrate somewhere in my museum) and see if that makes a difference.

More news as I have it ...

Your algae is worse than mine V!, and I don't do anything so the BNs and otos can graze on it.......

Another interesting experiment to follow. Smile

Well it is definitely working for me, could also be the EasyCarbo I am dosing daily as well. If you compare the two videos, looking at the Crypts and the large piece of bogwood, it is nearly gone in the second video.

The fourth dose of AlgExit has gone in. I was two days late with the water-change that accompanied it, but I don't suppose that matters very much.

Still not much/any obvious change to the BBA before I began the water-change but …

… there was a lot of fine particulate matter that had gathered in the Salvinia 'roots' and which I disturbed. I had a quick squint at it and it looks like dead plant stuff.  Also …

… when I did the syphoning-out I thought I'd have a bit of a poke at some BBA, and great clumps of it got torn off. I don't know whether or not this would have happened anyway, without the AlgExit, because I normally just leave it (the BBA) alone - fish seem to like foraging in it so I didn't want to clean it too much! Could it be that its attachment to its substrate is weakening? Also …

… when I looked more closely at BBA in the darker depths of the tank, I fancy it is actually receding.

I'm going to give it at least one more week before trying the calcium trick, to see what further progress there may be.



By the way - does anyone know exactly why Kuhli loaches go so berserk following a water-change? Is it the old "it's flooding, so I'd better get a bit of nookie" thing?

Looks like a few of us have algae problems.
I am just about to, reluctantly, dose my second lot of AlgExit. I do not like using chemicals unless I am forced to. My tank has a bad dose of BBA and AlgExit is my last hope.
I am aware the underlying causes of the algae need to be corrected but I want to try and reduce it first. I have removed rocks and wood, given them a good scrubbing, but the BBA just returns.
Looks like Ian (Wingnut) has had a good result from AlgExit, I hope I get something similar although I think Ian was treating a different algae.
I'll let you know how I get on.

Good to have brightened your day a bit!

It wasn't entirely facetious, though : flooding of rivers into surrounding land increases access to food for fish, and that can trigger breeding behaviour!
