So, I still have my planaria issue going on in the shrimp-mania and need some advice. I did a 35% water change yesterday and today a 15% because I saw a bunch of them in one corner and thought I will take that chance.
I know they came from overfeeding (not that easy to find the right amount) and since I use the blasting sand as a substrate, I can't really poke around in the substrate to stir it up and clean it thoroughly. I kinda touch up the surface of it and that way I can get some more out.
Now I know, using a dog dewormer is an option to get rid of them, but since there is a reason how they came, it kinda fights the situation, but doesn't fix the problem as I think they will reappear until I can figure out, what habitat of mine is causing them to be there in the first place.
Question: How can I take better care of the substrate to keep it cleaner? How many water changes are safe for the shrimp but effective enough to get rid of these planaria?
My maintenance is like a 10-20% water change biweekly. If that needs ti increase/decrease please let me know... I never changed the filter cartridge yet (tank has been running since July 2013) but I did "rinse" it in old water maybe about 3 times since then. The tank is a 20 gallon with a 75 gallon HOB. I use prime as a water conditioner and dose with Flourish comprehensive twice a week.
I feed about 2-3 a week half of a strip of the azoo food and fish flakes and other things, really small amounts... Too much?
Inhabitants are Red Cherry Shrimp, maybe all together about 40-60 I would guess, there are shrimplets everywhere and almost fully grown offspring.
I am happy about any suggestions
