Re: Removing phosphates #31
In the new water -

KH = 6 drops 107.4ppm

GH = 1 drop although it was really difficult to tell because the colour was so faint (17.9 - 35.8ppm)

I don't understand what is going on. When I usually add my RO/tapwater mix the ppm is around 100.

I just measured the new water and it measured 418ppm.

Re: Removing phosphates #32
It's 50 litres of water. I've tested the PH again and it seems to be 6.8. I initially added 1 level teaspoon (7g) of Neutral regulator and 1 level teaspoon (7g) of Discus Buffer as per the directions on the packets. The PH reading came out at 6.0

So I added one additional teaspoon of Neutral Reg at a time until it came back up to 6.8 (3 additional 7g, 4 tspoons of Neutral reg in total).

I'll go and test GH and KH now.

Thanks,
Fizz

Re: Removing phosphates #33
One more quick thing - does anyone know what re-mineralising does to GH and KH - should I still be testing these or should I assume that they will be fine with the remineralising?

I just checked the ppm in the water I am heating up for the water change is measured 376ppm since I added the re-mineralising powders.

Cheers

Re: Removing phosphates #34
Hi again,

I'm just getting ready for my first re-mineralised water change and just wanted to check a couple of things I'm a bit worried about.

I have added 50litres of RO to my mixing bin and added 1 tsp of neutral regulator and 1 tsp of Discus buffer following the instructions to take the water Ph to 6.8. When I tested the water it measured at Ph6.0. I then had to add another three tsp of Regulator to bring it up to 6.8.

Is this normal? Should I be worried? I don't really understand what has happened? Any thoughts?

My second question - can anyone recommend a really easy to read PH test? The API one is driving me batty as the measures for 6.6, 6.8 and 7 are all really close in colour and hard to differentiate. Tank water appears to be 6.8 now after adding discus buffer daily.

Please help - I'm worried I'm not up to the technicalities of this re-mineralising process and am worried that I may accidently cause PH shock to the fish.

Re: Decluttering again - but cats not fish #35
Sadly we have always failed with cats wearing collars and using attachments to open the cat doors! My oldest cat never used to put her head near enough the door so that the magnet would click and let her in... she used to push the door with her paws and of course it remained locked. I gave up in the end - the number of times I just had to get up and let her after she sat there and mewed pitifully at me made the whole point of the catdoor magnet a bit pointless! Given a choice a cat will always prefer human door opener

Re: External filter #36
I originally ordered an APS external filter with UV but it arrived in a state (the UV bulb was smashed and the casing was broken). I sent the whole thing back for a refund and then managed to convince myself to go for an Eheim 2128 Thermo.

I love this filter for SO many reasons. .It isn't as big as the APS one and fits in my Juwel 260 cabinet beautifully. It is virtually silent and really easy to set up for a non-technical person like me. And it heats the water to an exact temperature..... A smashing bit of kit and I am chuffed to bits with it. It filters up to a 600 litre tank and runs at about 1050l/h.

I run it alongside my existing internal Juwel filter which is great because the extra filtration is necessary with my current stock.

The only thing I would say is that it wasn't as cheap as the APS one - but since I decided to go for the Eheim II range - it did work out a bit cheaper than Eheim's in general - because Eheim have superceded all the pro II so most people are buying the Pro III or the PRO III i range (very technical and pricey).

Anyway, whatever you decide - I hope you'll be pleased with your external filter.
Let us know what you go for.

Re: Removing phosphates #38
I believe Violet describes it as learning to keep water, rather than keeping fish This doesn't mollify Mr F much when there's an RO unit running in the bathroom and a big red bin in the lounge full of water Nevermind eh?

Anyway, hopefully things will become more straightforward I really need to cut my expenditure on the tank for the time being - so hopefully this will all help with that.

Re: Removing phosphates #39
Have just tested the tap water - TDS is 300ppm so the 10ppm I'm getting in the RO is ok and I'll keep an eye on that from now on. Bit relieved actually because a replacement membrane is about ?20. I have ordered some replacement pre-filters from the same seller I bought the existing unit from so should be ok.

Is there anything else I have missed? Mr F thinks I've lost some marbles with all this 'faffing about' I do over the fish tank

Cheers Noodle

Re: Removing phosphates #40
Just checking... to work out if the RO unit is taking less than 90% of solids would be whatever the tap water ppm measures, divided by 100 and then multiplied by 0.9? Is that right?
