Do you mind ellaborating on the process a bit. Like how much per gallon? A little bit goes a long way. From memory 1 teaspoon of baking soda (sodium bicarbonate) raises the kH of my 55 gal by about 2 german degrees (~ 36 ppm). I use quite a lot as the water here out of the tap is 0 dkH and I run CO2 injection and need to keep around 8 dkH, so for each 25 percent water change I add a teaspoon or so, and then measure and adjust as necessary.

Diatom Filter or H.O.T. Magnum
Marineland has always provided that info and mine came with DE for use in
the filter SamB "TR" wrote in message k.net... "Randy Ocano" wrote in message ... I've been using a HOT Magnum for years for just polishing.The micron cartridge generally does a good job but on rare occasions I charge it with diatom powder. I doubt if Marineland recommends this or if it would void your warranty but it seemed to work fine. Haven't touched either of my vortex filters since I've started using the HOT Magnum. To charge the filter you'll need two input tubes, one for the input and the other for the output. Place the filter in the tank and submerge a small plastic pitcher and bring it up with the input and exhaust tubes in it. I then slowly dump a cup of diatom powder in it. Just received my HOT Magnum yesterday. Marineland now includes an instruction sheet for charging and using the micron filter with diatom powder. So I woudn't think there will be any warranty issues :-) Instuctions are basically as you describe. |

There is absolutely nothing in the instructions of mine to tell you how to use it with diatom powder. Rick |

I purchased the "HOT pro" kit with gravel vac, etc. On the flip side it has directions for charging with diatom powder, a fast method (simply pouring into the canister) and a better method, charging with a container until the recirculated watrer is clear. At the bottom of the slip are the numbers "004696", and perhaps a date "10/97". It does have the Marineland logo and address on the slip. Perhaps it is just something that comes with the Pro kits? I also ordered an extra cartridge, an honestly I do not recall if the slip was packaged with the kit or with the second separate cartridge. --Tom |

I just checked the paper that was wrapped around my Micron Cartridge and there is no such information. As a coincidence I have been swapping emails with one of their Customer Service Rep's. over problems I was having with my H.O.T unit and asked him about it. His reply was that if you have a filter that has those instructions in it then it is old and I mean old stock. According to him they stopped including those instructions 10 years ago when it became known that diatom powder was a carcinogen in airborne state. Rick |

I just ordered this from Big Al's. I suppose it could be old stock, but I would think that would be more likely to happen if I was buying from an LFS that didn't see much turn over, not from a mail order site like Big Al's. The box the Magnum came in has ©2002 on it, so I think that must be fairly recent. The filter I can't tell, but certainly the packaging appears recent. How reliable is your Rep? How long has he been with Marineland? Perhaps he thought you were trying to make a case for choosing a diatom filter over a Magnum and just tried to dissuade you? Who knows. Certainly alot of diatom filters on the market, and the media readily available. Seems odd for Marineland to take such a 'carcinogen...don't use it' stance. I may contact Big Als and see what they have to say. Well, I have no plans at this point to use diatom powder, but I do have the instructions if I ever feel the need :-) The micron cartridge worked very well. My biggest gripe is with the micro bubbles the Magnum puts out. The water LOOKS cloudy but it's not. Turn off the magnum for a while and it looks great. The micro bubbles are spewing continuously. Trying to reset the seals and use silicon lube, 'burping', etc. no luck yet. |

Trying to reset the seals and use silicon lube, 'burping', etc. no luck yet. I know nothing about the guy except he answered by query to the Company. This is my 3rd H.O.T Magnum. I also get the small bubbles however my problem with the other two was the unit purging the water from inside the filter only leaving about half and this then causes noisy operation and lots of big bubbles. Pain in the neck. The silicone did not work for me however I did get a laugh when the "Rep" suggested in a previous exchange that I use the small tube and if that was not enough to buy more at the Hardware store and use copious quantities. He said that the problem is the D ring which does not seal properly. I told him that if I had to use copious quantities of silicone then I would suggest they have a manufacturing defect in their product. The new one works fine with the exception of the small bubbles. Here is his rely to my query. Hi Rick, Glad to hear that you got the issue resolved at the store. Regarding the use of Diatom Powder, this is something that has been used in the hobby for quite some time. We used to include it with our Magnums until we discovered that diatom powder is a carcinogen in an airborne state. This stuff is known to cause cancer. For that reason we stopped recommending its use. The micron cartridge by itself can filter out particles as small as 4 micron. With the use of diatom powder I think it brings that number down to 2 micron, not that much difference really when referring to such a small particle size. If you do choose to use diatom powder, simply hang the Hot Magnum on the tank. Take a small container, such as a milk jug with the top cut off, to isolate the intake and return tube. With the container full of water and the tubes isolated, turn the filter on and add an amount of diatom powder to the small container. The filter will continue to circulate the water inside this small container. Allow it to run until the water appears to be clear again. All of the powder is now going to be attached to the micron cartridge. Simply lower the small container to introduce the intake and return tubes back into the tank. Do not turn the filter off, as this may cause an amount of diatom powder to loosen up and shoot back into the tank when its turned on again which may have an adverse effect on the fish. Is sounds to me like the person on line had gotten a hold of some older stock if he had found instructions regarding diatom powder in the manual. We have not recommend this stuff for at least 10 years. I hope this is some helpful information. Please feel free to contact me if you have any further questions or concerns. Thank you, Matt Bennett Marineland Customer Service 1-800-322-1266 x4474 |

Hmmm, thats disappointing to hear about your bubble problem, and lack of solution. If it wasn't for that myself, I'd be thinking I have found the perfect filter. It really irks me that the tank is actually quite clean, but looks so cloudy due to the bubbles. If I can't resolve it, I'll be buying another filter (shhh, don't tell my wife), maybe a rena Filstar 204 or something similar. I'll keep the magnum for its ease of use and micron filtering, but not as my primary filter. I've lubed the D ring, and the inlet o-rings, so far not enough to make an improvement. It also bothers me that the D-ring seats in a channel on the LID of the unit, rather than in a channel on the canister. Heck, if you don't have a lot of silicone lube on the D-ring its likely to fall out as you try to place the top back on the canister. Seems like the channel ought to be on the canister. I think the Magnum has a lot going for it, but a few design quirks keep it from being as good as it could be, IMHO. |

They are handy though and easy to move from tank to tank. I borrowed a System 1 diatom filter from a friend and this little unit is amazing. Much easier to use than a Vortex. Hangs on the tank and can be easily moved from tank to tank. I had quite a bit of free floating algae in my 77 heavily planted tank. Hooked this think up and it was amazing how clear the water was within an hour. The next day I used it in my fish room. Charged it with 5 tbls of diatom powder and did 10 x 10g tanks using the same charge. Nice little unit. Rick |

It sits on the floor, and has a completely round ring. Like the HOT version, though, it too is on the lid, not the canister. When in a not paying enough attention, I have had a couple issues getting to stay on properly..... it didn't take long to notice it.. a few drops spurting out, air back-filling into the canister... To date I have not had to use the silicon that came with it. crosses fingersknocks wood --Tony |
