Brown leaves

[chris10]

I think the answer to my question is more co2. Did a search but couldn't find anything about leaves turning brown.

My Crypt spiralis is starting to turn light brown on the edges of the leaves. The middle is still green. I am dosing flourish twice a week and the kh ph co2 comes to 24 ppm which I know to most of you means crap. Drop checker is coming.

lights are a little over 2wpg at 10 hours
Co2, from a pretty consistent diy jello using wine yeast (2 three liter bottles), is mixed in a reactor.
Pressurized is down the road since this tank I set up was for a local non profit animal rescue.

Heres a pic
just to let you know that is a UGF tube, but it comes from the top so no actual UGF

You are starving your plants. Flourish is like dessert to the plants. They also need meat and potatoes - nitrates, phosphates and potassium. Those are cheap to supply, if you buy some potassium nitrate and mono potassium phosphate from Greg Watson.

Flourish does provide those nutrients but not sure if its enough.

No, they do not.

You'll need some KNO3, KH2PO4, and perhaps some GH booster, fear not, they are very cheap and last many years for a few $ and they are very easy to add.

See Aquarium Plants, Aquatic Plants, Planted Aquariums, and Aquarium Plant Fertilizer

How big is the tank?

46 gallon bow front

Then do this:
Get the ferts from Greg.

50% weekly water change
Add 1/2 teaspoon 2x a week KNO3
Add 1/8th teaspoon 2x a week KH2PO4
Add 1/2 teaspoon 1-2x a week GH booster
10 mls 2-3x aweek of Flourish

That's it. Make sure to add enough CO2 and stay on top of that.
