Hmmm, I don't think there's any reason not to put them in. They might absorb a little water over time, but not enough to destroy them and they wouldn't be toxic. I say go for it.
And I don't think anyone genuinely expects an extremely high level of a grammar and punctuation. Messageboards are informal enough that if your post wouldn't make a 4th-5th grade english teacher flunk you then you're doing fine. I know mine certainly isn't perfect.
To use it as terrestrial plant fertilizer siphon it out and pour it on the garden. To use it as aquatic plant fertiliser don't siphon it out.
I suppose you could filter it out as you siphon, then dry it, compress it into little tabs and put them under the plants...Hahaha...Too much trouble.
Try putting his a 3:1 mix of his old food and his new food in a container of water, stir it up for a little while so any juices and smells will be hopefully transferred to the new food. Then dump it in.
Hopefully he'll start eating the new food an you can start increasing the ratio.
Nah, won't come anywhere near blowing them out of the water. A nice current at best. A lot of fish people keep are river fish and rivers flow much faster than just about any pump could get a tank moving. My 440L has around 8000 lph of flow(Assuming everything's pumping what it's rated at)
I'm advising if you want to be sure they'll stay shut to put some kind of latch or similar on them.
Jeez people, sometimes I'm actually serious, not sarcastic, learn to tell the difference! :lol:
There are a bunch of pumps that are available in powerhead versions and pond pump versions. The difference? About an extra 20 meters of power cord on the pond version.
And the people that use the wrong their, there, they're, too, two, to, lose, loose and spell bought with an R. All are valid targets for ridicule.
People that use "of" instead of "have" are optional targets.
