Does anyone else use the Fluval U2 filter? I've been running a second hand one a few months now and the venturi valve has never worked. Today the filter packed up so I went to my LFS and bought a brand new one and the venturi doesn't work on that either. Is it a design fault? I have a U3 in my other tank and that one works fine.
I'm about to start setting up my second tank. I've had to wait a few weeks while some work was carried out in my kitchen. In that time I've had a piece of bogwood and a sponge filter running in my main tank in the hope that they seed with good bacteria. So my question is this; Once I put them in the new tank what next? Do I add a little bit of ammonia to see if it gets processed by the good bacteria? If not what do people suggest I do? Thanks for any comments and advice.
Can someone tell me if this is brown algae? (See pic). It's developed since upgrading my lighting to one of these off ebay. https://www.ebay.co.uk/itm/30-200-cm-A ... 61975837?var=424387119422 It's on everything!! I've introduced some Zebra Nerite snails after taking advice from elsewhere. I've put 4 in a 110 ltr tank. Are they as good as people say at controlling algae? And how long does it take them to get it under control? If indeed they can. Thanks.
I decided not to use Tetra safe start or any equivalent product. Instead I added liquid ammonia and let the bacteria develop naturally. It's taken best part of a month adding small amounts of ammonia every couple of days and testing the water. On Wednesday of last week I did a water test and the nitrite level had fallen off a cliff with a reading of zero. Ph 7 Hardness is 7.05 German degrees according to Severn Trent website.
Hi all. I've been cycling a new tank over the last few weeks and we are just about ready to start putting fish in. My 4 year old grandson is insistent on having some neon tetras in there. So my question is what other fish can I put in with tetras bearing in mind that I want some shrimps in there too? 110 litre tank. TIA for any suggestions.
