It's that time of year again when the water is starting to warm up, fish are starting to feed, water starting to get mucky as the fish start disturbing the sediment, and the dreaded green algae starts to build up in the water reminding you that it's time to change the UV tube.
I bought a twin pack of 36w replacement tubes but as it turned out it was not only the tube that needed changing but the ballast had also failed and was no longer available as a 'part'.
So a bit of delving and research and a new stainless tube'd UV steriliser was ordered, they're supposed to be more efficient than the plastic bodied type.
I was pleasantly surprised when it arrived, a right bit of kit and certainly looked the part. The one advantage it had over my faulty one is that the tube and inlet/outlet are larger. I'd found several times that they would start to block up with debris and slow the flow down, often thinking it was the pump that was partially blocked.
Anyway, less than thirty minutes later, the old was out, the new was in, the filter vortex emptied and the pump back on. The lamp's now happily glowing away doing it's thing.
I'll give it a couple of weeks and then get the vac out to clean any sediment and flush the filters out again - onwards and upwards
If anyone is interested, I got the 36W version of this...
