Symptoms - Cryptocoryne beckettii
I have a Cryptocoryne
beckettii in a 29g planted discus tank that is the center piece of the tanks and
really something to see ! It has thrived and grown very large and
beautiful over the last 6-9 months. Lately I have noticed some light gray
streaks appearing on more and more leaves and some indication of progressive
decay on some of the smaller/newer leaves. Most of the older leaves are
large dark-green/red and show no signs of distress. I am trying to figure
out what may be causing this ??
Up until a couple
of weeks ago I had 3-20w lights and have added a fourth 20w florescent totaling
80w. The original tubes consisted of 2 Coralife Trichromatic and one
Coralife 50/50. The fourth tube added is a Coralife 10,000K. I use
DIY mylar reflectors in both of the double-tube
Co2 - Consistent
20-30ppm by Lamontt test kit. Injected (as of Christmas present from wife, did
not expect this one .... what a shock !) 1 bubble/second into Advanced
Reef Tech reactor (not thrilled with this reactor design because I think it lets
too much Co2 escape).
Fe ~ .1
Nitrates/Phosphates: Nitrates are sometimes
consistently a little high in the 10-20 range, never over 25ppm.
I use Seachem's phosphate
and Puragen resins in the magnum for excess Phosphate/Nitrates. With
planted discuss tank and with feeding beefheart I think this helps control
P/NO3. I also vacuum some of the top layers of substrate with water
phosphates in a while. Hold on a second....... P = 2.5-3.0mg/l (SeaChem)
NO3 25mg/l(Tetra Kit). YIKES these are high ! I am using the
low-range Seachem P kit. In the directions it says: "Usually,
freshwater phosphate concentrations will be beyond the range of this kit (0.0 to
3.0), and dilutions of sample with distilled water will be required. If
excessive algae growth is not a problem ( and it is not, NO hair algae in the
tank), then the phosphate concentrations may be considered as
acceptable". Well ok. Does this sound ok the ADPers in the know
?? Just did a water 30% water change and will test again tonight
diluting the test sample.
Pond Planting Soil (this is just very fine fired-clay granules w/ supposedly
good CEC, no organic matter in it), DuplaK lateraite balls pushed in
deeply. I may lack Ca/Mg in the substrate after thinking about it
DuplaPlant tabs (the smaller ones for 20l), drooped in Magnum 350 with weekly
30% water and filter media/floss cleaning, 2-3 DuplaPlant24 drops/day. No UG
heating at this time. Maybe on the new 90g...I wish !
Bi-weekly add 1-3
tsp... Kent's Fresh Water Plant Food if I think the plants are showing
signs of iron deficiency or if my useless RedSea Fe kit looks on the low side.
It measures .1 usually, (It looks like I need to invest in the Lamott or Hatch
Fe kit after all).
I Feed sparingly
2 3-4' Discuss ( 1 high-fin turquoise and one red) I soak Jack Waltney's
and M3's DISKUSIN with Kent's
Zoe vitamins over night. Also feed tetra flakes, Spirila (sp?) and tetra
Other fish include ~ 10
tetras, 6 SAEs, 2 Corys and 1 plaeco that is getting to big and may have to go
to another tank.
Other plants look good and growing well except for
two Amazon swords that seem to have stopped growing all of the sudden and are
developing green algae on the leaves. Java Fern (getting more algae) ,
Hygrophila polysperma, Sunset Hygrophila, Anubias barteri v. nana,
Lilaeopsis brasiliensis, Aponogeton rigidifolius, and Bacopa caroliniana all
seem to really be perking up with the addition of Co2 (Duh!).
Back to the question at hand - I am really
concerned with these gray streaks that are developing on the Cryps. Any
Thanks in advance for you thoughts on this and all
of the wonderful dialog from all APDers.
In Virginia where
it's been 60-65F over the last few days.....go figure or go El Ninyo.
