Undergravel filter caused major problems

A few observations-

1- UGFs work fine, if you know what you are doing. RUGF works even better and is less work.

2- Fry basically need two things- multiple small daily feedings and DAILY tank cleaning and water change (10% or so).

3- Bare bottom tank makes managing #2 easier.

4- Failing to change your water and clean the tank for 2 weeks caused your problem.
 
Yep, I agree. When raising fry you must do frequent water changes. That way you can feed them a lot AND keep the tank clean. Bare bottom is best. I wouldn't ever use a UGF anymore because I just feel it gets too nasty under there and I like HOB & canister SOOOOOO much more. Also, I haven't personally experienced it but I've heard many times of fry being sucked down because of a UGF. You know I really think that the "fungus" you saw in the tank was probably rotting food and the fish got fungus because of the resulting poor water quality. Live and learn, I'm sure your next experience w/ fry will be better.
 
Yup, if the suction is powerful enough they'll get sucked up. I would rather spend a few extra bucks on something that keeps my tank clean, that I don't have to clean every week.

As someone here once told ME to do.... take that old fashioned style filter and smash it to pieces!!! ..
Wow! Such excellent advice, and to the point! No "beating around the Vallesinaria" there.. LOL

It's seems to me it's not really 'personal opinion' on whether or not to use UGF's, but rather poor advice. If one already has that product in their tank, then keep it vaccumed - often..

I can't see anyone 'advising' someone to go out and get a UGF for their new aquarium.... There are much better products available that actually "filter" the water!

(ReverseUGF's work opposite of UGF's so I won't drag out this post anymore.. ..They are also 'not' filters.)
