being produced. I know that some fish keepers were using the RD-PRE with power heads, instead of the RD-30G for greater
However, the RD-30G was a very good filter for the money. And the fact that it is only one of a handful of HOT canister filters
on the market should have ensured its success. Anyway, I am glad that I purchased mine when I did, and at the discounted price
of $19.95 each...
UPDATE: 9/25/14 - The water flow on the RD-30/RD-PRE combo that I use on one of my planted aquaria was greatly reduced after having run this filter for four months, so I took the canisters apart to clean them.
The RD-30 was actually quite a bit dirtier than the RD-PRE, which shows that the 30 does a good job of absorbing much of the detritus that is filtered through its media compartments.
Several people have complained of how difficult it is to open the media trays for
the RD-30, and this has been my experience as well. I lift off the top tray which is easy to do, then open one side of the rest of the trays in order to rinse the media. I remove the mechanical media and I just rinse the biological media while it's still in the tray before reinstalling the media tray in the filter chassis.
The RD-30 (especially with its RD-PRE companion) really does work quite well, and for a more than reasonable price.
UPDATE: 9/9/14 - I have been running a pair of the AquaTop RD-30 filters on two of my planted aquaria for several months now (one with the RD-Pre attachment) and
like them very much.Read more ›
difficult. However, the same filters are manufactured by a few different companies (all likely from Taiwan)
under their own names. Can't remember the names off hand here, however, if you Google AquaTop RD-30G
you will likely find them. They are sold through venues such as Ebay and Amazon.com
There are two caveats with the RD-30G and RD-PRE that someone contemplating purchasing these filters should consider before actually buying them.
The first is that these filters are impossible to prime unless you fill the water right to the top of the canister (to the point where it's about to flow over the edge of the canister).
The second is that the media trays in these canister filters are interlocking and nearly impossible to separate.
The answer is to get a pair of scissors and cut clasps that hold the trays together, so that trays can be
removed independently from the RD-30G.
When adding the RD-PRE pre-filter to the RD-30G, this filter doubles the filtering capacity of the RD-30G. I have used this combo on a Mr. Aqua 17.1 gallon aquarium, and was very effective l at keeping this tank clean. I also used it in combination with a Marineland 350 and a Cobalt Aquatics DUO 500 UV sterilizer.
If you find these units on sale on Amazon or Truaqua.com you'd best snap them up while you can, because for the money you won't find a better filter on the market. They are cleverly designed, well made, and do a great job of filtering your aquarium water.
The RD 30G is rated for up to 30 gallon tanks, and the pre-filter doubles this capacity to a full 60 gallons.
I paid $35 for the pair and liked them so much that I purchased another pair for the same price.
Well worth the money and highly recommended, even if you have to pay a bit more for them.

Design wise it's near perfect, save for some fingernail busting maneuver when separating the baskets. I have to shave the plastic link
