Sand Filters vs. Bead Filters

Here is today's Pond Q&A, with questions about filters and winter feedings..

But first, some more readers reviews of 'The Scarecrow'

==

It works! So far. I received the scarecrow yesterday and immediately set it up. This morning Mr. Blue Heron came in for a landing in my pond and the little scarecrow creature went crazy and Mr. Heron flew away.

He landed on my neighbor's roof and pondered the situation for awhile. Then tried it again. Little scarecrow went crazy again and Mr. Heron had had enough and flew away.

The only down side is that the scarecrow sprays joggers and cars, too. I may get kicked out of the neighborhood...

Question>

HI THIS IS ANA in Pt. Charlotte Fl

Please Help me, what is the difference between a sand filter and a microbead filter? I am in a rush, cause my dad wants a sand filter and I don" think that is the right kind.

Thank you Ana in Pt charlotte

Well Pat, let's just say that 'Sand' Filters are great for swimming pools, but terrible for ponds. In pools, they work effectively to 'polish' the relatively clean water by filtering it through very small granules of sand. Add some fish waste and other organic waste to the equation, and you've got yourself a mess. In ponds, they clog quickly, require almost daily backwashing, and can also grow anaerobic bacteria (smells like rotton eggs).

Bead filters, on the other hand, were designed specifically for fish hatcheries and ponds. A Bead filter provides excellent biological filtration, due to the large cumulative surface are of the beads for colonizing beneficial bacteria, and they are also excellent for polishing the water without clogging easily. They are also easy to backflush, easy to maintain, and easy to use. In short - we love 'em!

Question>

Hello First of all i love your Q & A's. I cant tell you how many of my questions/concerns have been answered just by reading these. I live in western Pennsylvania. The change of seasons in this area are so extreme that today could be 75 degrees and sunny and tomorrow is 45 degrees with rain.

I know not to feed the fish (1 koi, 2 comets/shubunkins and 10 new babies) after the water temp drops to 50 degrees. But my water temp changes as often as the air temperature. My question is if the water temp fluctuates should I still resist the urge to feed them until Spring? This is the first winter that I wlll have left the fish outside. Thank you in advance. Kim Ladasky, Pittsburgh PA.

Hi Kim, thanks for your compliments.

Ok, well it really depends. You wont necessarily harm them by feeding them a little here and there, just use your best judgement. But you definately don't want to give them a 'feast' right before a cold spell. Again, fish don't have stomachs and the good enzymes that digest their food are less present in cooler temperatures, so excess food can actually rot in their gut if they are feed too much when it's cold.

So, a 'light' feeding sporadically would be fine untill it cools off, but then again - they will survive just fine without it.

Hope this helps..

-- Happy Pondkeeping!
