75 Gallon Plant Log
 
6 Attachment(s)
Keep track of my plants growth and ask questions....I have had some of these plants (not sure what some of them are) for about a week to a week and a half.

First question is my are some of my leaves becoming transparent and dying? Most of the swords started doing that yesterday.

Second question, the tall sword one leaf, and only, one has turned brown why is that?

I have two flourish root tabs in and I am dosing with Flourish comprehensive

How bright are the lights, and how long are they on per day?
I need some suggestions for plants in my tank, here is a thread that you can go to for suggestions:

When many plants are moved to a new environment, the existing leaves will frequently die off. Echinodorus (swords) do this most times. The new growth will always appear from the centre of the crown. Older leaves at the outside can be removed if they begin to yellow, or you can leave them initially for a time. Some nutrients such as nitrogen, phosphorus and potassium are what we term mobile, which means that the plant can move them from the older leaves to the new leaves in order to promote new growth. This is useful when such nutrients are insufficient in the water. So leaving the obviously-dying leaves on for a bit means the plant can take some of the stored nutrients from those leaves. I usually remove any leaves I see yellowing though; with regular fertilization this is n to usually an issue.

Another cause of this deterioration of existing leaves in newly-acquired plants may be due to the propagation. Nurseries propagate aquarium plants emersed, as bog plants, if the species grows this way, as swords do. So the leaf form will be the emersed, which is different from the submersed form. When the plant is placed in the aquarium submersed, within a few weeks the emersed leaves will die off as the new leaf growth in the submersed form appears.

With your fertilizing scheme you should not have issues growing swords, so it is almost certainly either or both of the above since you have only had the plants a week or two. Just look for new growth; if the new growth is very pale, almost white, that might mean insufficient nutrients, but don't jump to conclusions, since all new growth is naturally lighter in colour than the more mature leaves. I do see new growth in some of the photos.

Another point is that changes in the environment--such as switching fertilizers, lighting spectrum, intensity or duration, and water parameters--can take anywhere from a few days to a few weeks to become evident in the plant growth in response to these. And again it is always the new growth since the change that will show this; existing leaves that may be yellowing or dying will not turn around and recover.

No mention is made of light, and that is a vital factor in all this, as it must balance the nutrients. The photos seem OK in this respect, but of course I can't tell the actual intensity (or duration) from the photos, so more info on this might suggest something.

Final comment, on the pots; I assume you left the plants in their clay pots until you decide where you want to plant them. Once you do, I would remove the pot and unwrap (carefully) the rock wool and remove most of it, but being careful not to break off roots.

Triple bulbs for light, one that came with the tank and two that are labeled aquarium and plant. Atleast one or both fixtures are on for 8 hours each day.

The thing that doesn't make sense is that the translucent leaves on some of the plants are newer ones but there are even newer ones growing in green. On some of the other ones it is turning translucent.

Is this a standard 75g, so 4 feet in length? And are these tubes all 48-inch tubes?

One thing I see I forgot to mention/ask, is the GH of your source water. The hard minerals (calcium and magnesium particularly) must be sufficient in the source water, since the Flourish fertilzers (and other brands like Florin) do not have sufficient of the hard minerals to make up for deficiencies. If your GH is 5 dGH (roughly 90 ppm) or higher, this is not the issue.

I've heard that sometimes too much light for low light plant will make their leaves translucent.

From what I remember the alkalinity was 180ppm. Yes about the lights

If you are in to aquascaping, here is a new thread just for this!

Alkalinity is the carbonate hardness or KH, which is not what we want; we need to know the GH or general hardness, which is the measure of hard minerals 9calcim, magnesium...). This can affect plants (and fish), the KH does not.

How long are the lights on daily?

Can't find GH....help?
