Hi bro,

I am so sorry to hear that your Hydra stream LED had malfunction again. We had not been receiving such feedback from Singapore community but nevertheless, we will check on it how we can improve on the stability of it. Rest assure that your hydra stream is still in working condition despite the LED is down as the wire connection with the reaction plate is not link. You may bring it back to our retail shop at your convenient when you visit Singapore again, thanks.

One of our customer recently started freshwater fish keeping about a year ago, had bought a 60cm tank and had been using OF Hydra 20. After some time, as he added more fishes, his friends recommended him to change the Hydra 20 to external canister filter as it has a bigger filtering capacity and also look more professional. Therefore, he replaced Hydra 20 with a new external canister filter.

After using the external canister filter for a few months, due to the filter getting dirty, he decided it was time to wash out the filter. But as a new hobbyist without the knowledge of biological filtration which his external canister filter is running on, he did a major clean up on the external canister filter and water change and might have also killed off all the beneficial bacteria in the canister media.

Three days later, he suddenly noticed that the fishes that he had kept for some time started to die and majority of them floating lifelessly just below the water surface. He gave us a called in the evening asking for help to save his balance fishes. After finding out from him that it could be a case of ammonia spike and that he still had the Hydra 20 on hand, we advised him to put the Hydra 20 into his fish tank immediately and run it because we know that Hydra’s Hydro Pure Technology can detoxify the water.

He called us back 30 minutes later, informing us that some of the fishes started to leave the water surface and have regain stability. The next morning, all of his balance fishes are back to normal condition and no more death of fish had been notice since the moment the Hydra 20 was put in. He commented that the Hydra 20’s ability to quickly detoxify the aquarium’s water has saved the balance fishes from being totally wiped out. He will keep the Hydra20 in the water until the beneficial bacteria builds up in a few weeks.

Below are the pictures in sequence that he has allowed us to share with the community.

Hi, i have been using hydra 20 on my 2feet tank for quite some time now and i have noticed that there are orange deposits on one of the metal plates in the filter. They are rather hard to scrape off therefore i just left them there. May i know would it affect the peformance of the filter?

Hi I would like to ask if i change water 90% daily. Will hydra still be beneficial?

Dear QianHu,

I have bought a Hydra Stream I for my 5.5ft tank.

I clean the Hydra Stream I once a month, but have a cleaning question.

Namely, the metal plates, the side that turns dark brown, do I have to scrub it until it is sparkling clean again?

I tried to used toothbrush and scrubbed with force, but it is still dark brown even after much scrubbing.

Please advise how clean the metal plate has to be to work at maximum efficiency.

Pictures/illustrations would be greatly appreciated. Thank you very much.

Hi,

The brown color deposits on the one of the plate is normal as this is due to the reaction from the plate and cata pure as one of the plate is 'sender' and the other piece is 'receiver' It will not affect the efficiency of OF Hydra.
