Simply Koi and More Koi

Hi Dave, this one's easy as we both use the same RO kit. The unit is 300 US gallons (240 UK gals.) per day, current system cost for the pumped version is around £330 inc. vat. Systems without the pump aren't worth the space they take up. They will not actually produce these figures due to the fac...

Right Gazza, the results of the rope heater on the RO water mains feed pipe. A winner I'm pleased to say, throughput has increased by 41%! I've used a 500w, 5mm x 3m rope heater, wound tightly around a length of 15mm copper pipe. The winding covers around 1' of the 2' of copper pipe I've inserted in...

Sorry for the delayed response Gazza, but in the last few days I've been in 4 countries! (including the UK) When I fitted new carbon cart's I simply left the system on backflush (in fact a misnomer) for an hour, which I now know simply follows the normal flow path, but all water goes to waste. This ...

I got the Flowmaster meters from Ro man, one installed in the waste line and one on the mains input, the differential being the RO product volume. My pressure guage shows 90 with new cartridges, but to be fair I've yet to find an accurate guage of the needle type generally supplied in the hobby. I h...

I will not be flushing any new carbon cartridges straight into the RO membranes again! Just installed a valved bypass line linked into the waste line. took the opportunity to tidy up a few other lines as well, it was beginning to look like the mad scientists lair in the filter house. What pressure d...

I think you will find that groundwater may have more dissolved minerals, but I know without doubt it would not have anything like the suspended fines the average pondwater has. OK, I need to get something clear here, are we discussing reprocessing pondwater through an RO system, but minus carbon sec...

We must look beyond the function of the membranes, the amount of fines in pondwater is several zillion percent higher than in tapwater, regardless of how you prefilter it. The effort required to remove those fines at the sediment prefilter stage would require a cartridge per day, I use one every 14 ...

OK Gazza and all, I have news. Fitted the RO man cartridges today, little or no difference, flow still pathetic. Spoke to RO man, who suggested it sounded like RO membranes were clogged. To test I removed the output (product) pipe from each in turn and fed the output to a measuring jug. He was right...

Hi Chester, I can see where you're at with regard to reprocessing the pond water through a sediment filter. However there's little chemical benefit to be had, it becomes a small mechanical cartridge filter really. Adding RO membranes in there will definitely not work, regardless how clean you get th...

Hmm, same here so not that then! Did I mention that as you have a higher production rate than myself I've treated my system to a rope heater? I ordered this today, 500w @ 240v, 3m of elemement, which should cover about 1' of the feed pipe to the RO system when tightly wound. I'm going to insert a co...

Hi Gazza, mad? I know not but I doubt it, but I'm sure you can see where I'm coming from. Your system is producing more output than the manufacturer claims possible at anything remotely resembling current temps and water pressures. On the other hand, a simple measuring jug can't lie, can it?!!! I've...

Incidentally Gazza and all, one of the carbon cartridges I am currently using is half the price of the equivalent from RO man. But, I notice that the design is considerably different, instead of a flow through casing it has a flow down design with a solid casing. Water enters at one end and exits at...

As I had to order some original RO prefilter cartridges from RO Man I ordered the meters also from that source.

Just in case Gazza has got 180 gpd, I've ordered two of the inline water meter/cart condition indicators by way of consolation!
