Hey all,
Recently I've had some issues w/ 3 species in particular and thought someone here could assist w/ some ideas for cause/solution with me.
Plants are/were:
Staurogyne (or Schismatoglottis roseospatha - can't see much diff betwn Plant Finder Id of Stauro or this link to Schismatoglottis :
http://www.victri.net/plants/_schismatoglottis.html )
along w/ P helferi & Blyxa japonica
I had recently renewed my CO2 and for a day was shooting way more into my tank than I should have been. During that time, pH fell from mid 6s to high 5s over night.
Fish lived but didn't like it
My substrate is ecocomplete topped in a few spots w/ granulated peat so tends to be rather loose.
(question part II - is <2" eco enough? think i should add another inch or something more compacting perhaps??)
And, I had begun regular liquid fertilization but cut back following a rapid incr in green algae on leaves and glass - though wallichi did finally redden up
(question part III; lack of red consistent w/ lack of some macronutrient (NPK)??)
Results:
P helferi simply melted over night
(like a crypt, stems rotted at base and most of plant dissolved *fast*)
(P. erectum appears to be undergoing same issue - but also has been moved recently and doesn't tend to like that in my experience, so could be unrelated?)
B japonica has been simply coming up much faster than it used to.
(tends to float up when it gets too busy and I've recently taken quite a few runners off of it - so may be coincidental - related to quest part II)
Staurgoyne has also begun to come uprooted and stems appear to be somewhat *mushy* for lack of a better term.
There is a small patch of Eleocharis parvula surrounding Staurogyne. But it doesn't appear to of any concern now, or prior to the problem showing up. Nor does it appear to have undergone a growth spurt and choked out Staurogyne growth;
P helferii was planted in a clearing so no other plants to overrun it ...
QI - rapid decline in Kh (pH) leading to plant meltdown?
QII - substrate not deep enough, or too porous?
QIII - nutrient def in wallichii; green consistent growth but not reddening and also somewhat leggy/scraggly prior to beginning fertilizing regime.
Ideas; thought, all welcomed.
I appreciate the feedback.
Tank specs:
75 US gal; Minimal/infrequent water changes; loose fertilization method (capful here / there in an attempt at regularity over spurts); lighting 12 hrs 4X65WPC, cylinder CO2 - in the 2-4 bps range; keeping pH around 5.9/6.0 range (do test that regularly - to keep the Dicrossus and Apistos happy)
Yeah, I should do better, but they grow and I can live w/ that. :wink:
thanks in advance,
