Sagittaria & Vallisneria
The LFS (The Fish Store & More in Atlanta) said with this new light, I
should start by having only 8 hours of light per day and gradually increasing it to no more than 12. I see no point in doing this. Your lights are bright, but not *that* bright. Again, the LFS said CO2 injection is not *really* required and all it is said to be just because of high lighting levels. CO2 *is* required with high light levels. Otherwise, you will constantly be battling algae, and there will be undesirable daily pH swings. See my posts in the "75 or 90 for planted?" thread. Several of the guys there said they have never used CO2 with high light levels and have always had great results. I'd be curious to see what they consider high light. In general, CO2 is not necessary with less than 3 wpg (though it can help). Over 3 wpg, though, and CO2 is required, not optional. Concerning the PH, again the LFS said the Angels and Loaches would enjoy the 6.5 more than 7.5. I would not adjust the pH just for plants or fish. The vast majority of them will be fine with any reasonable pH. As long as you're not trying to breed cardinal tetras or something, leave the pH alone. The way I am doing this is by using SeaChem's Neutral Regulator with the Discus Buffer. These do contain phospate buffers. Is this really a bad thing? It will be, without CO2. If you want to lower your pH, adding CO2 is a much better, and easier, way. Leigh http://www.fortunecity.com/lavender/halloween/881/ |
