    I don't know if anyone has done this before. :rolleyes:

    Chladophora has been bothering me for a long time, regularly manual removal did not solve the problem at all. Seven weeks ago after doing routine maintenance and removing most of the algae on the substrate, drift woods and plants, I decided to take a risk on cidex(2.4% glutaraldehyde). I dosed cidex at 25 ml in the 42 g tank. One Caridina denticulata and MANY Septaria porcellana were killed on the next day, but all fishes remained alive.

    This is my NPT infected with chladaphora. 90x45x45 cm with T5 39Wx2.

    One week later I found that that remaining chladophora shrinked and withered. I dumped another 25 ml of cidex into the tank, and another week later futher shrinkage of the algae were noted. Althogh chladophora was not eliminated, I was satisfied with the result and stopped dosing cidex.

    Unfortunately chladaphora regained its growth 2 weeks later. And last weekend I saw the familiar picutre, the annoying chladophora was back!X-(

    Hope my experiment would help others with chldaphora problem.

    Thats a nice slideshow.

    25mL of 2,5% glutaraldehyde in 160L /42G = 3,6ppm, most snails/shellfish will be killed at that concentration.

    But since some of the algae survived, it will grow back.

    I tried dosing double conc. of excel every day for several weeks, but it didnt help.

    I think you could try to risk, dosing 25mL every week after waterchange. Observe the clado and see if it disappears totally.

    I think the shrimp/fish are eating the dead algae so pruning it first and then adding cidex could reduce the amount the shrimps are eating. Maybe stop feeding them could speed it up?

    To avoid problems you should try to use the spot method, it while allow high amount of gluta to be in in contact with clado without dumping the whole bottle in your tank ^^

    Dear Anti-Pjerrot,

    Hi, I use to run the water of my pond through a UV box and that was the only way I got rid of algae totally in my pond. I don't know if it is a good idea to use it for an aquarium, especially I plan to keep some shrimps. I am at present feeding my fishes with live brine shrimp fires.

    Your advice please.

    Warm regards^:)^

    I also use 2,5% gliuteraldehyde 10-15ml/100l with water changes. Plants have a better growing. :-"
