I don't know of any articles on Reverse flow undergravel filters unless I wrote it as I am the only one I know who uses one.
I will try to explain it on Monday or tuesday.

Hi Paul...This is the way to go...so many times we see or hear of a fish or coral going south then we start trying to fix this and that ..instead of just leaving it and wait it out as all normally sort itself out in a few days or week especially in a matured tank..now by disturbing the hole tank for that one coral or fish we sometimes sacrifice the rest of the tank mates ...Also I agree with you re the lifespan of a fish you mentioned in a other tread..I have 3 fish that’s been with me now over 10 years and am proud of it...haven’t lost a fish other due to my stupidity jet in 10 years...my hat goes off to you...and for the reefers not reading your tread and learning from you... sorry for them...when I read or hear of someone that has been keeping a tank for even 10years or more I read their story to see if I can’t learn something from them...It’s a pity that technology gets followed instead of the basic principals in keeping marines..so many livestock gets lost due to this what I mean is you read of so few guy’s keeping marine for even 7 years and longer and more newbie’s come and go with in the first 5 years as most guy’s insist trying new technology only to pack it up as a lost cause ether to expensive or time consuming and to mush hustles keeping all the gadgets working ...so you keep posting and I will keep learning..Thanks for your valuable input and information.I am not sure why, but I left it in the tank and didn't niotice it any more as it fell behind the rocks. Today my urchin carried it to the front like he does with everything that is not nailed down and the thing is growing back. There are 4 dime size patches of life on it and it was completely bare. I am happy about it but it is wierd. Another montipora is also growing faster than I have ever seen these things grow. This is just one of those strange things that we can't explain. I am leaning towards coral wars as nothing I can see happened and the rest of the corals are fine. The same thing happened to my Birds nest and now it is growing relatively fast.

Now of course we have the internet so we can get a whole lot of mostly incorrect information. I went through a lot of fish before I learned how to keep the things alive and healthy. The internet is kind of a deterant sometimes and wrong information is so abundant that it is taken for granted that it is true. Just mention UG filters and fifty people will post and say, the thing can't work. How many times should I come on and have to tell the entire story? Hair algae, people still say to add a sea hare to "cure" hair algae. It is not a disease and can't be cured. A sea hair does not even prefer hair algae and even if it eats it, it will grow right back. The stuff disappears on it's own and that is why there are so many rumors of different animals "curing" it. But that is for a different thread where people will argue with me so I probably won't get it started. Ich is another one. It is the easiest thing to cure and keep your fish from dying but all I hear is garlic. I eat garlic and don't get ich so maybe it works. This is not rocket science and it is not an expensive hobby (after you set the thing up) Fish want to be healthy and live forever, if they die, it is always our fault. The fish was healthy when they caught it, it will stay healthy if we learn a few simple cheap things to do to keep them healthy. Quarantining is great but it is not the answer. It is one way but to me, not the best way. I will try to start a thread of "my" ideas on this. But it is only "my" opinions from "my" experience. Everyone should eventually through experience tweek this for their own particular situation.
For a REEF tank, reverse UGF will not work, as it will be a nitrate factory.

Just learn what fish in the sea do
but do you guys do anything to condition your top-up tap water, apart from letting it stand for a few days?
I don't even do that
I do the same
Steve i use on tap mixed with kalkwasser..hi Jaco, gebruik jy ook kraanwater om op te top vir evaporation? of gebruik jy RO daarvoor?
RO water, being stored is not good. Especially if container is open. Due to all the dissolved minerals and whatever else being removed, it is very easy for the RO water to take up any flavours or chemicals hanging around in the air around it. Test it, put RO water in open container in your fridge for 5 days. Taste it. And you will taste the other open foods in the fridge. So no, do not store RO water for long periods (my opinion - 1 week).but do you guys do anything to condition your top-up tap water,
You just have to stand back to be able to see it.100% of this hobby is common sense.
You as human can pee most of it out of your body
