Aqueon 15W 8000K full spectrum tube
I got a flourescent tubelight with the specs listed above for my 20 gallon tank. I was wondering if it is the right kind of lighting to grow plants.
That should work fine.
I put in a Java fern, java moss, japanese moss balls. I'm getting a cryptocorne wendtii, C. usteriana, and moneywort. Any need to fertilize?
The tank is a little over 2 months now with 5 zebra danios, 5 albino corycats and 3 platies.
Depending upon the afore-mentioned, you might be OK without, but a good liquid is Seachem's Flourish Comprehensive. You use so little it is long-term not expensive. Once a week a 1/2 teaspoon is sufficient.
The hardness is 300 and pH is between 7.8 to 8.4 (closer to 8.4). I use Aqueon water conditioner...from the label it says that it detoxifies heavy metals released from fish waste. So I guess I'll get the liquid fert. you mentioned. If I can't find it, is there another one you recommend?
Also, you mentioned that I shouldn't vacuum the substrate...will I do only water changes from now on? So far I used to vacuum the gravel since I only had plastic plants.
I got another light question. I hear about 2W/gallon rule. I only have 1 light fixture for the hood I currently have. Do I have to find a hood with 2 fixtures? I can't find 18-inch tubes that are 40W...they are all 15W each !
The 2W/gallon "rule" doesn't take into consideration newer light bulbs. There are some bulbs that use 32W of energy but give 40W of light. So it's a guide. I have a 20 gallon with a single 15W 8K bulb on it and have the wentii, moss balls, and java fern that you have and they grow like weeds.
I also use the Flourish Complete too. You can get it from Petsmart. They will have the large bottles out by the fish food but the smaller bottles on the end cap with the "live plants" in tubes.
Sweet. I just need to get the fert. Will head over to my local Petsmart this eve =0)
As TwinDad noted, the "watts" is not accurate due to the various types of tubes which today give more intensity in their role as energy-saving or greater efficiency.
A single tube will be fine for the majority of plants, any noted in our profiles as low or moderate light will work.
On the Flourish, make sure it is the Flourish Comprehensive Supplement. Seachem make several different products under the "Flourish" name and the bottles look very similar.
