How To Advantage’s of Under Gravel Filter Urdu/Hindi
I recently joined this forum and was somewhat surprised by the number of hobbyist who dislike undergravel filters. I have had a conventional one in every tank since the 1970’s, and since this adds up to dozens of undergravel filters over several decades, I thought I might be qualified to clear up a few concerns. I only went to reverse flow a week ago, (Thanks for the advice, Bryan!), but can already explain some amazing benefits of this set-up too. This is my opinion based on many years of experience and I am entitled to it. If you feel otherwise, don’t flame me. Instead, post a response expounding your own experiences and let the readers decide for themselves.
From what I can tell, the most common undergravel concerns are: 1) They are “old technology” and have out-lived their usefulness in the hobby. 2) They offer poor filtration. 3) They are not suited for growing live plants. 4) “Muck” collects underneath them and is impossible to remove. 5) They clog up constantly, fouling the tank and creating maintenance woes or killing the bio-mass of beneficial bacteria. 6) They are hard to clean.
In the same order, here are my responses:
1) They are old technology for sure, but this alone is a ridiculous reason to avoid them. The latest, most expensive and complicated solutions are not always the best answer to life’s simple problems.
2) They do offer very poor mechanical and chemical filtration, but when properly maintained the biological benefits are huge. And remember, biological filtration is the most important and the one you can never have too much of. In conjunction with a good power filter, they do offer worthwhile benefits.
3) I am not a horticulturist, neither in gardens, pots, nor aquariums, so I wouldn’t argue with this except to say that not everyone cares about it. That most all tropical fish will thrive in unplanted tanks with 3 different types of filtration (biological, mechanical, and chemical) along with regular partial water changes is an established fact. I prefer the look and convenience of artificial plants, and undergravel filters are fine for this. I also enjoy replacing my expensive bulbs only when they refuse to light up – about every 5 years and sometimes much longer.
4) Totally agree, but not a problem with pre-filtered, reverse-flow powerheads.
5) Not if kept clean. And again, not much of a problem at all with pre-filtered, reverse-flow powerheads. These push only filtered water through your undergravel filter solely for the benefit of biological filtration and do nothing to clog the substrate. Indeed, the reverse flow option may even keep gravel cleaner than using nothing because it discourages floating debris in the tank from settling in it.
6) Hogwash. Until last week I had used a conventional undergravel filter in every tank I have owned (about 25 total) for well over 30 years, and sometimes nothing else. And as long as I did not over-feed the fish, the gravel only needed cleaning about once a month and could be stretched to twice that in under-populated tanks. This is done during bi-weekly water changes and adds no extra time to this simple responsibility. All you need is a bucket and a simple, inexpensive gravel siphon. Coincidently, the siphon tool actually makes scheduled water changes much easier and is probably something you will want to own anyway.
