Hello all,
I've recently installed my new pressurized Co2 system on my 29 gallon tank, and am now starting to pay more attention to my fert. routine. A quick rundown on my tank...
Specs -
29 gal.
Eheim 2236
Nova Extreme T5HO 48w
T8 5500k 18w
Red flourite/topped with sand/and some eco complete
pressurized Co2 @ 2 bubbles per sec. Inline DIY reactor. (works great)
Seachem's Iron/Flourish/Trace
This is the tank as of last night, major trim 2 weeks ago (not in any shape to show)
I am following Seachems "Suggested dosing" chart, but only with the -
Flourish Iron (3 ml. a day)
Flourish (2 ml. every other day)
Flourish Trace (2 ml. every other day)
Sundays get a 22% water change and a full dose of all the ferts. Prior to having the Co2 system in place I was dosing excel daily, but have discontinued. The tank pearls every day in the evenings after about 4.5 hrs of constant light. My lighting schedule is as follows...
On - 7:00
Off - 10:30 = 3.5 hrs
On - 3:30
Off - 10:00 = 6.5 hrs
= 10 hrs a day
Co2 turns on an hour before lights on, runs all day, and off an hour before lights out.
It is my opinion that the tank is adjusting to the change in Co2 right now, I've recently found some small holes in a couple leaves here and there. My original thought was potassium, but I'm not sure. I'm estimating that I am running on about 2.5 watts of light (approx. 4 gallons of displacement in the tank). Should I be adding more ferts than I have mentioned above. Is it maybe time to shift over to another product line for dosing?
Tank health is good, although before Co2 I had a little bit of hair aglae. That has been replaced by some healthy staghorn, which I have had in the past....it's just never pearled this nice
Any suggestions to my dosing method or products i'm using would be very helpful. I've been very happy with the Seachem line, and I have a good local retailer that sells the small bottles for 8 bucks. A price I am fine with.
As always... thanks for the help
