The Sera 500 uses a 16/22mm hose connection. I recently posted some information about poor quality control on the Sera unit I bought. Easily remedied and now working very well on the outflow from my 1500L/h filter.

In an effort to minimise the amount of equipment in my 100L cube, I replaced my CO2 diffusor with a Sera 500 CO2 reactor. I added this in the outlet pipework of my Eheim filter which is rated at around 450L/hour. I found that the rotors in the reactor slowed down and stopped almost immediately...

Fragments of Riccia

I've had one of these Rena tanks for a couple of years and found it very good. The Rena filter which came with it is powerful and quiet and I've had no issues with it. My tank came with two bars with T8 lights which rest on ledges under the covers - well made but not enough for the job. I sold...

Here's a short video of our Four Foot Jungle Tank taken earlier this year (Spring). Since then we have had great success with the cryptocorynes which are even more lush than in this clip. CLICK ON THE PICTURE TO OPEN UP A 1 MINUTE VIDEO CLIP OF MY TANK

I have a pressurised CO2 system and I feed daily with a PMDD solution, traces mix plus a small amount of phosphate solution. I seem to be able to grow most plants apart from any type of sword plants which my Ancistrus destroy and any Hygrophila/Ludwigia species which always grow explosively and...

As well as being a giant I think it may also qualify as one of the oldest plants I've ever kept. Although I'm sure it's been through several generations, I bought the originals from a long closed shop in Bradford in about 1990 or 1991. John

Pics attached of the monster Crypt. The biggest leaves are bending over at the surface which I reckon makes them 65-70cm long.

How big does Cryptocoryne wendtii get? I have several plants which I bought as this species which seem far larger than I expected. They look just like in the pictures but the largest just touches the surface of my 60cm deep tank. The actual leaf is 20-25cm long and 4-5cm wide on a 30-35cm...

Anyone had any experience with ordering CO2 from this firm? They come up on internet searches for cheap disposable bottles but I've had a disappointing time with them. Paid for a bottle two weeks ago and I haven't received it. Can't raise them on the 'phone and they won't respond to email...

Many thanks for the advice - this is what I suspected. Guess I'll be selling two full welding gas bottles and having to buy the very expensive Dennerle replacments.

I have an oldish (about 10 years) Dennerle regulator and have been using their 500g disposable cylinders. I bought what appeared to be an identical cylinder from Machine Mart - however the thread diameter is the same but appears finer than on the Dennerle original and will not fit. Does anyone...

The list seems to be a real mixed bag - I can't see how some of these species can be a problem if we continue to have cold winters? Maybe they know something we don't about climate change. On the other hand some of the plants have potential to be a nightmare. I had a holiday on the Gironde in...

I've also grown red root floater (Phyllanthus fluitans) in quite dim conditions. It goes green and is much less vigorous but grows OK. Agree with Darrels comment on LImnobium - it will grow OK in low light. I have loads of both - PM me if you would like some. John

I have used WS3 and the Pets at Home own brand white spot cure (which appears similar to WS3) in planted tanks with no problems at all.
