  1. So this is just some feedback on the Hydra 50 and Hydra 20 filters we purchased a little while ago. I'll just try and keep this post short and sweet. Firstly, if you don't know what they are they are a filter which has a set of electronic metal plates inside them and as water flows over them they basically zap the water and kill or neutralise ammonia, nitrites, nitrates etc. I don't know the exact science behind it all, I just know it works. Here are some examples of where it has worked for us. 1. We started a new cichlid tank, placed our fish in and switched on the Hydra filter. No cycling at all, it was filled and stocked on the same day. A couple of days later we woke up and our tank looked like milk, you literally couldn't even see more than 10cm into the tank. It took us 4 days to work out that the gravel we'd been given secondhand, and washed a zillion times, was riddled with dead snail shells which caused a huge bacteria bloom. So we pulled it all out and replaced it with new stuff. Through all of that and readings of Ammonia and Nitrite completely off the charts, but our fish swam around just as happy as could be. It didn't bother them at all. We were a bit confused by the readings but it turns out that if there are high amounts of ammonia etc in the tank it may talk a few goes through the filter before it is all removed, but in the meantime it just neutralises it. 2. We started a live bearer tank, placed our fish in and switched on a Hydra filter. No cycling at all, it was filled and stocked on the same day. Has been there now for over a month, hasn't had a glitch, all fish are happy, water is crystal clear. We didn't need to add the fish in bit by bit either, we decided what we wanted, got them all on the same day and put them all in. On this tank, the Ammonia and Nitrite is never above zero and the Nitrates sit somewhere between 0 and 5 depending on the day. (we've now done this with another tank that contains cichlids and had the same results) 3. I haven't done this one but I've seen it firsthand. One Hydra filter and some salt added to a tank and left overnight, marine fish added (clowns and seahorses) and weeks later happy fish and not one issue. These filters do have to be removed if you ever need to medicate because they'll zap and neutralise the medication so we have one fully cycled normal filter ready to go at all times. So basically I think they're amazing and I would recommend them without hesitation. We almost didn't purchase one due to negative opinions on them but all of those negative opinions were from people who had never owned one and just 'thought' it wouldn't work. I'm glad we tried it for ourselves. I think Tech Den and Red Dragon Aquatics both have these.
