Water changes

Postby L.Poore » Sun Aug 26, 2007 10:36 pm

I wanted to do a topic on water changes. I currently do 30% a week. I would like to see what others are doing and how often filters are cleaned.

I only ever clean my filter when the return flow slows down. My last filter clean was 12 months ago (that was a Jebo 819. The little internal filters need cleaning every few weeks as they gunk up faster). I do a water change every 2 or 3 months.
My tank is heavily planted, under stocked, well filtered and has been running for over 10 years so well matured (like me!)

Umm... I do 30% water changes every 7-10 1/2 days. My filter only gets cleaned once the water flow has weakened. I just put up my new setup about 3 months ago. Never had to clean the filter yet. :wink:

Rio 400:
I try and water change this every 4-5 days, taking 25%-30% out. This also includes using a syphon to get the waste off the sand & stirring the sand. The white pad in the filter gets either rinsed or replaced (depending how it looks after rinsing!). Carbon pad changed every 4 weeks. Every 3-6 months i will rinse a course and fine sponge and swap their positions over and clean the impellor. every 12-18 months i will syphon the gunk out of the bottom of the Juwel filter box (its a bit of a sand trap).
I also have a Rena XP3 on this tank and that gets looked at every 4-6 months (or maybe when the water flow looks weak, cant really put a timescale on it) but that gets sponges rinsed out and positions swapped, the substrat media gets rinsed and the piece of polywool gets replaced.

Rekord 60:
pretty much weekly water changes of about 50% with gravel syphon. white pad changed weekly, carbon changed every 4 weeks (Juwel have a pack that is 1 carbon + 4 white pads for this filter)
Sponges get rinsed eventually but never at the same time. Impellor gets cleaned about once a year.

A lot depends on the size of the fish. Oscars are very messy fish and need a lot of water changes.

I do a 20% water change each week and also change the white filter pad. About every 3rd week I use a syphon to clean up the gravel and get the gunk out. Also follow the guidelines for the other Juwel internal filter pads as to when to change them (although I do tend to just rinse them out as I don't feel its necessary to replace them quite as often as suggested by Juwel.)

I do a 25% water change/gravel siphon every 2-3 weeks. Clean my impellers every few months and almost never change my fiter pads unless they are falling apart. My ehiem external filter has been cleand once in the last year. My internal fliter that I have on my 20long tank gets a swish in the removed tank water every time I do a water change.

I don't really have guidelines, it's really as i think of it which can range from 5 days to 2 weeks. Occasionally i forget about it and do it once a month, but not since i added more fish, then it was just three fish in large tank. I remember about 2 years ago i changed the water every 2 days foro almost a month because i was bored (Summer hols). :oops:
I aim for 30% but again i do as much as i feel like at the time, sometimes it's 10% other times i am taking nearly half the tank out.

I have not done any water changes on my new 29 gallon tank. It has been set up for two months. But I have plants in there. Have never had plants before so this should be a learning experience. In my 75 gallon, I rarely did water changes, just added fresh water once enough had evaporated and cleaned the filters once the water flow was reduced. I have two very big filters on this tank.

You should still do water changes, despite the filtration and the plants. :)

I do about 25% water change and gravel siphon every 2-3 weeks, though I've been a bit lazy lately. Should probably do it again soon. I clean the filter monthly approximately, or when it starts making annoying noises.
