GH and Algae and Plant Health

OK. I have been making water changes every other day and have reduced the GH down to about 1/2. Here is a picture of a plant I just placed in the tank about 2 weeks ago as an experiment. You can see some translucent spots starting to apppear on the leaves. The stargrass near it is suffering the same problem and is just about dead. Following all sugestions that have been made including eliminating the excel. Any futher help is appreciated.

Thanks,
Walt

I read back through this thread and would mention that there was a lot of "stuff" going in the water and it takes time to clear all this. Also, the plant issue was mentioned previously, so that is not the result of the changes. Just to clarify.

Now that I've seen a photo of the plants, I may be able to suggest more. With water as hard as yours, there is a lot of calcium and magnesium in it. As with most nutrients, more of some without a balance of others can be detrimental. So in a sense, this is connected to your GH. Trace minerals are probably in too short suply; these are easily removed by binding with oxygen and such. This is a case where Flourish Trace and Flourish Comprehensive would probably help. There are some trace minerals in Comp that are hot in Trace (iron for instance--this is essential for swords and indeed all plants) so I would use both. Get a small bottle of Flourish Trace Elements and use as directed.

Now that I've seen it, I have had this issue (the "transparency") occur, it came with an increase in magnesium. It has also recently occurred in my 70g with the Flourite substrate, in which I had reduced the Flourish (the trace elements in Flourish Comp were missing I suspect). So I think we're on the right track.

KH is different, and something could be affecting the carbonate/bicarbonate levels. And once KH lowers, so normally will pH as the buffer is gone and the natural acidic tendancy of the biology will be free. The GH itself has no impact on pH. The two are usually "high" or "low" but not always, as here.
Byron - I am also having issues with high GH/KH levels, and I see you indicated using 75/25 mix (RO/Tap Water) Also, you wrote that the GH can only be lowered by diluting the water with pure (soft) water. Are you saying to use RO soft water or soft water from a water softener?

The only way in my opinion to safely lower the GH in an aquarium is by diluting the water with what I'll call pure water. This is completely natural, no chemicals, salts or whatever substances are being added. This means either RO or distilled--both of which have no mineral content--or with "softer" water such as rainwater. The reduction in hardness will be in proportion to the mix, so half tap and half RO/distilled will result in water that is one-half the hardness of the original tap water. Rainwater will do much the same thing, though there might be some mineral depending upon what it has "picked up" falling to the ground.

If fish are present in the aquarium, the change must be gradual to avoid shock. When the hardness lowers, so too will the buffering capacity and the pH will lower, and this also must be done slowly. This is why I suggested a 25/75 dilution, and that took into account the initial hardness and what would result. If the initial water is very hard, less of a dilution should occur to avoid too great a drop at once.

As for water softeners, it depends. I've never used one, some other members here have with varying problems/results. If the softener "softens" by replacing mineral salts with other salts, this can be just as bad for the fish.

TY Byron for helping me out with my hard water issues. I have never had a water softener and was thinking of putting one in, but maybe I need to look into a whole house RO sytstem instead. I will deffinately do what you suggested and do the 75/25 to adjust my tank.
