cryptocoryne issue

[Cornhusker]

tom,do you think that faster rate of growth of the crypt wendtii under compressed co2 conditions might cause the leaves to get holes?lutea and other crypts in same tank don't suffer same issues. the leaves on the wendtii look great,then start getting holes,then deteriate. i pull those leaves then in a while same condition starts again. regards,cornhusker

No, it's a nutrient issue.

Re: cryptocoryne issue

I'm having the same issue as Cornhusker with my Crypt Wendtii's and Giant Hygrophila (also some edges of leaves look like section was eaten). Ludwigia loses leaves but other plants, Bacopa C., Rotala Indica, Elodea Najans, E. Tenellus and Java ferns are looking great. Leaves on the Bacopa are the largest I have ever seen (attribute that to EI, CO2 and extra light).

I am using EI with Flourish (5ccs) on non Macro days, flourite substrate and plants are pearling like crazy. CO2 is at 35ppm, water temp is 83 daytime, KH 5.6, GH 9 (add Equilibrium and Bicarb at weekly water change because tap water is 2.5KH, 4GH), NO3 at 20ppm, PO4 at 2, 3.5WPG of light for 12 hours/day, 30 Gallon Long tank. Lights are GE9325 CF.

Any idea which nutrient would cause this? I believe I have most of them covered.

Thanks, Mike

Re: cryptocoryne issue

I have had zero luck with crypt Wendtii's, every other crypt has done well. The only Wentii's that have worked for me are crypt Wendtii var. Tropica.

Re: cryptocoryne issue

I decided to add K2SO4 at 1/3 tsp and Epson Salts at 1/3 tsp to my Macro dosages 2-3 times a week for my 30 gallon. Since I am doing 50-60% water change each week, that can't be too much, can it? If that fixes the problem, then I will do as suggested in other threads and start cutting back those nutrients and watch the plants for signs of deficiencies.

Thanks,

Mike

Re: cryptocoryne issue

Add some more Traces/K2SO4 and also a little MgSO4.
Also reduce the light peroid to 10 hours.

Re: cryptocoryne issue

ok tom if this is a nutrient deficient problem,then please correct my dosing. i use plantex csm+ boron=4 tbsp in 32 oz container,also adding 2 tbsp of epsom salt to mix. 75 gal tank,flourite,comp co2,220 watts ah supply lighting on 10 hrs.heavly planted and lots of livestock. at 50% water change i dose as follows,KNO3=3/4 tsp,, eq=3/4 tsp,, so4=3/4 tsp.. next day 20ml of trace.

wed w/c
thu trace, 20 ml
fri trace, 20ml
sat KNO3, 3/4 tsp
sun trace,20ml
mon KNO3,3/4 tsp
tues trace,20ml

would FLOURISH or TMG be a better trace to use? at what dosage for flourish?
at what dosage for tmg,and is this product a concintrated liquid for an econimical purposes?
cryptocorynes grow like gangbusters for me but have this problem with deteriation. thanks, cornhusker

Re: cryptocoryne issue

Try 1/2 on the KNO3, 3x a week.
Other wise, crank the CO2.
