Today I bought my Hydra 30 new type, and realise that in the Hydra 40 and Hydra 50 when I open up the catalogue/manual within it. Can I know is the Hydra 40 available for sales now??

The other thing i'd like to check is, your old Hydra 30 can treat 100 ~ 300l, however, the new Hydra 30 state that it can only treat 100 - 200l, does that mean that there's an efficiency drop for both types? If yes, I will change back to the old one instead.

Anyone monitor their nitrate while using this? Does it work effectively?

Hi QH,

I bought the Stream 1 and attached it to my pump with flow rate 6500l/h.

Is it too fast for the catalyst to break down the nitrite?

Thank you

Hi , where did you buy the stream 1? how much does it cost??

I bought at Aquarama 2013 yesterday.
Good price, I feel if the filter do what I need it to do.

My only concern is whether the flow rate is too fast for the breakdown.

Just bought the Hydra Stream 1 yesterday at aquarama. My nitrates and nitrites are the same. But one thing did change alot was the PH of my water. From 6.2 yesterday it shot up to 7.2 today. Ammonia still remains at 0.50

May i know what's the diff between the Hydra stram and Hydra 40? Mind sharing the price? Am considering placing it in my slump tank last compartment.
