  • We are currently upgrading MFK. thanks! -neo
I was hoping would say their stock then their water change schedule.
My ten gallon betta tank gets 50 - 100 % changes weekly.

My 20 long with stunted cat, bristle nose pleco, and deformed peacock cichlid gets 25% on Mondays and 25% on Thursdays.

My 75 with the 9 inch red devil gets 25% on Mondays and 25% on Thursdays.

I test about every 3 weeks for nitrates. before water changes, helps me not just for water schedule but protein/feeding management.

50% weekly. Or when ever there is a lot of waste on the substrate.
 
Kind of off topic but.... Where do some of you live that you're using rain water for your homes?

If I tried to rely on rain water I would be die lol.

and to expand on that a bit, what kind roofs do you have. being a roofer for 26 years. roof run off has some nasty chems that leach from the roofing material. treated shakes have arsenic, asphalt shingles have petroleum. same with Bur roofing whither moped down or torch down.

I use rain water only for fish tanks. Not for regular house hold use. (I wish I had it planned to use at household too when I built the house)
Well, my roof has asbestos roofing sheets. My indoor tanks gets water collected in a barrel stays there for a day or two and then in to the tank. The outdoor ponds get rainwater directly from the down pipes from the roof. The rain is seasonal of course and I need to rely on the tap water for the dry season.

I have to admit that I didn't pay attention to any chemical effects (people with roofing material knowledge can elaborate more on that). However, I've been doing this more than a year now and I have not seen any ill effects.
 
I live here and rely on rainwater collected on out galvanised corrugated iron roof to supply our house and my tank. My tap water usually has a TDS of around 006PPM so it is very pure, despite there being a bit of leaf litter on the roof and in the tank. It is common practice here, with most of rural NZ relying on roof water, so I doubt they would be able to build houses with roofing products that will leach toxic stuff into the drinking water supply.

If you are going to use rain water for your fish you need to be aware that it has no mineral hardness whatsoever (unless you store it in a concrete tank!) and you will, in most cases, need to provide something to buffer the water to prevent pH crashes. If you're keeping Amazonian fish it is very good (generally speaking), if you're into rift lake or central american cichlids you're going to need to buffer it with something.
