"If you are sure that you need Potassium, simply go to any store that has a garden supply and purchase a product called "Grants Stump Remover." It is KNO3."

I've been adding "Green Light" Stump remover (potassium nitrate) and "Flourish" Potassium (Potassium Sulfate) to my tank. Is this overkill for potassium?

My Scapes

Prune most of the leaves with holes but at the same time you don't want to totally strip the plants. The leaves will not regenerate and fill in the holes so they will all eventually need to be removed but if almost all of them have holes you may not want to do it all at once. Just remove the most badly affected ones to start, then continue to prune them off as new healthy growth fills in. That's how I would do it.

Wow! This Forum has really gone crazy since I have been here last. Thanks so much for everyones help!

Should I cut off the leaves with the holes in them? Sadly is most of them. I think I am going to get some of the stuff from Seachem. Its on sale right now on my web site that I buy stuff from. Thanks again!!

If you are sure that you need Potassium, simply go to any store that has a garden supply and purchase a product called "Grants Stump Remover." It is KNO3.

Sorry, Frank but I think using KNO3 for Potassium supply would be a real bad idea.

KNO3 will increase Nitrates as well as the potassium, and seeing as the reccomended level for potassium is 20ppm, dosing to that level with KNO3 could quite possibly result in levels of nitrate that are toxic to fish (depending on his current N03 levels).

I'd stick with the Potassium Sulphate or Potassium Chloride.

It may not be a Potassium deficieny, but as Potassium is difficult to overdose and is not an algae inducer, it's worth a shot trying. Potassium is quite often deficient in aquariums.

Ashura,

I doubt that it would be this animal, although nothing is impossible. I found a website that lists this as its feeding habit:

“Gammarus are scavengers and feed on microscopic algae and protozoans normally found in pond water. If keeping for longer periods of time, introduce aquatic plants into the aquarium which, as they break down, will provide food.”

In addition, I would assume that these animals would be a very good food source for the fish and would not survive too long in an aquarium where the fish population is much higher than in nature.

Hi, before judging to the lack of Potassium the plant leaves might be ruined by Gammarus sp. a kind of small crustacean that makes lots of holes on leaves, whether old or young, only liverworts and stem plant are difficult to get attacked. Gammarus looks like a small flea, grayish, about 2mm long, difficult to see especially if your tank is full of plants. Would this probably the case?
