Picotope with HC - brown/yellowing patches

[Uggs123]

Hi folks. Was wondering how to remedy this.
I have a tank which I did a dry start on with HC cuba for foreground for 6 weeks in which I experienced some nice expanisve green growth. I flooded the tank about a week ago & now have brown & yellowing patches and small dying patched.

Also, just did a trimming of HC (was a lil bushy) to try to stim lateral shoots. Mostly top shoots.

The tank setup is as follows:

3 gal JBJ picotope
azoo palm filter
eco-complete substrate
Perch-Light Compact Fluor Fixture - 13W 7400K - photoperiod 14+ hrs
Ferts - EI method- w/ (1) weekly 50% water change
NPK - seachem NPK - 3x weekly -scaled down to 3 gal from label instructions
Seachem flourish - 2x weekly - scaled same
Seachem Excel daily - scaled same

Would like to eventually add hair grass or Microcarpea minima in rear. But, would first like to get tank on point.

Any ideas whats causing it ?

Thanks.

Hi,

Flooding does cause some changes from the emersed to submerged form..

14 hours + of light is A LOT. Remember that with DSM they get plenty of c02 from the atmosphere.

I don't see where you are injecting c02???

If not, this is also a big change for them to adapt to.

Keep in mind that commercial liquid ferts are mostly water so your dosing may be less than you think

I have a Seachem dosing calculator based on their dosing chart if you would like to use it. It's in Excel 2003 form. If you want to dose more of the products, just enter more gallons in that section. Since it is Excel based, you can modify it as needed. FertFriend is a nice calculator for Seachem's products. You can calculate your dosing ppm with it. The fertilator is another Seachem calculator as well as Seachem's calculators on their site too.

Thanks, guys. Very much appreciated. I scaled back the lights to 9-10 hrs & up'ed the ferts. Thanks for the fert calc Left C.
Yes, I'm not injecting CO2 at the moment. Plan to have it setup with 2 weeks or so. Stuff is in the mail. I guess until I get that up & running I will continue to have blue/green algae patches colonizing the HC.
I make a habit every evening to comb it out. I see the importance of the CO2.

Trying to figure the dosing from Seachem's chart is a PITA. That's why I wrote the Excel based calculator. You can add other items to dose with their own formulas to that calculator. Just use its "unhide" feature to view the formulas and add anything that you want.

Do you see the nano CO2 regulator that yikesjason built? http://www.barrreport.com/showthread.php/7278-A-Primer-for-Pressurized-CO2?p=51681#post51681

That thing is amazing ! I PM'd him for a "how to". Cool thanks
I have the Taam CO2 controller setup with a 20 oz pball cylinder for almost a week now.
My HC starting to pearl here and there, so my guess photosynthesis is taking place and hopefully on right track.

Guys thanks again
