My tap water (severn trent) has about 0.5ppm of chlorine. I recently dealt with someone who had 0.25ppm, so it wouldn't show up on most home test kits.

Ive used these before. I agree its a great cost effective UV. The bulb is a sealed unit, you can't get in to clean it. Just replace the bulb unit if it needs replacing. I've found the bulb lasts about 2 years with 8 hours/ day usage. The bulb failed before it showed any sign of needing...

Hi Colin. Been a while. Waterlife went out of business a few months back. You can still find old stock for sale, but they they will disappear once they run out.

1 watt/ litre is normally sufficient unless your aquarium is outside in the cold. I'd be surprised if they operated more than 5 minutes in every hour. So thats going to be a couple of hours a day of actually operating. If you are heating large volumes of water though, it's more efficient to...

Have you reattached it to see if it works now you know the filter is primed?

Then there is something blocking the clarifier. Are you sure you opened the aquastop valve before turning on the filter? Could you try just running water through it with a hose? Have you tried re-attaching the clarifier again now you know the canister is primed? It doesn't really matter if the...

I presume its connected to a fluval canister? Id check whether it connected on the right line, and that the aquastop valve was open but if it was, it sounds like your fluval canister isn't priming, which can be difficult with fluval canisters. My solution would be to detach the aquastop valve...

If your polishing media gets clogged up and reduces flow, you can use the Xtender dial to redirect water flow and keep your filter operating for a bit longer without needing to open up the canister and changing the polishing pad.

Methylene blue.

Turn the leaf over. If they float to the surface its just trapped air.

Looks like air bubbles trapped under the leaf.

This medication is a single dose treatment. If you need to repeat the treatment, wait 7 days, big water change and then redose. Carbon will remove this medication from the water, so yes, a big water change and then carbon in the filter is a good wat of removing the medication from your aquarium...

Im not sure specifically what "calcified water rock things" are. If they are calcium carbonate they will very slowly disolve and raise GH and KH if you have soft acidic water. If your water is already harder and higher pH then they will just sit there in the water and do nothing. I would start...
