Theres more water than air in here :P


« on: March 01, 2011, 07:22:32 PM »

Im just wondering would adding a co2 system to my well planted tank aid in any way with the health of my plants which are basically all hardy type plants such as anubias nana/java moss/bacopa caroliana/water wisteria and amazon sword? ????

The substrate is carrib sea instant aquarium sunset gold sand

The lighting is Juwel T5 highlight 45 watt 890mm long day and nature tubes

Wont a diet of nitrates and good lighting keep these plants happy either way ????

Or would the addition of liquid fertilizer or a co2 system or both liquid fertilizer and a co2 system give me lusher healthier plants ????

Also while on the subject what do people think of Seachem Flourish Excel as an alternative to a co2 system ?

Gunnerd,

I don't have CO2 and I grow:

Java Moss (and it really grows!)
Ambulia (wow, they need pruning every 2-3 weeks)
Crypts ( growing well)
Anubias (v. slow growing, but good enough)
Amazon Sword (ditto)
Banana Plants (survive, but don't really grow much)

I believe you need to look at CO2 when you get into high-light tanks and species. But never tried it.

do you "need" co2 and ferts? No. your plants will always do better with them but if you are running low light and start adding ferts and co2 it will just be more to pay attention to. if your plants are not dying now then you should be ok with out it

Unless you are at or over 3 wpg, all you will get with the addition of C02 and ferts is excessive algae growth.

i would have to disagree. i only run about 2.3wpg with daily ferts and pressurized co2 with very minimal algea growth. it really depends on how much time you are willing to put into it getting the correct balance of co2, ferts and light. if you are running a lower light set up, with the addition of co2, your plants can more redily use the light that is avaiable to them

With pressurized you would have more control - with DYI you have too much fluctuation (which is what I had) and that was the point I was making.

2x36W under reflectors up 95USgal of water.If we can say: reflectors give more 50% of light,that means i've 0.3Wpl or 1.14Wpg !
Its LOW! that's why i add macroelements as EasyCarbo every morning and microelements as ProFito every 7th day.
In my option,i think 1.14Wpg with Philips 865 TL-D (daylight)spectrum bulbs is enough to lighting tank ''ONLY'' 7-9hpDay...
Its so bright ! I like it.
So...in that conditions i can give co2 injections too BUT its NOT neccessary!
If you like that co2 canister so much,that mean add some bulb and regular fertilizers for 100%.
Like on pics.432W only at 4ft lenght!~400,-usd

  I know very little about plants, but every time I see the watts per gallon rule mentioned, it reminds me of the inches per gallon myth.  I know that it is just a rough rule of thumb, but wouldn't a more accurate measure be watts per so many inches of depth?

It would be, yes. Even more accurate is a measurement in lumens. Smiley However, it's difficult to think of it in those terms, and watts per gallon is easy, especially for beginners.
