Water changes just for plants?

Planning on starting a heavily planted 220 gal. Thinking I'll have a light fish load, but wondering how much work I'll have to put into water changes. I'm willing to spend to make things as low maintenance as possible (within reason), so I just want to make sure I'm not biting off more than I want to chew.

If you run a low tech setup you don't need to water changes often especially with a low bio load, so you might only have to do them every 2-3 months. High light setups usually require fertilizing and as a result require weekly water changes.

Just need to water change every blue moon to take out things that the plants dont absorb.

Limit the light intensity to low light - 30 micromols or less - and you will have as little tank maintenance needed, including water changes, as possible. What lighting do you have or plan to have.?

I haven't decided on lighting as I haven't decided on plants. I didn't realize that low light plants = less maintenance. 1/3 water changes on a 220 every other week versus every other month is a lot less work. I wasn't thinking about going low light. That may send me back to the drawing board for a bit. Thanks!

When you deal with large tanks, you want to use a system where you pump the water in and out of the tank. The last thing I want to do is be lugging buckets of water.

I use a large powerhead connected to a long clear plastic tube. I set up a 50 gal rubbermaid trash can, fill it with water, add what ever I need. Then the next day use the pump to remove about 50 gal of water, and then use it to refill the tank with new water.

Just get a Python or a Lee's Gravel Vac and then you don't have to even deal with trash cans for holding water or any of that jazz - just hook up to your sink, take water out the tank, put fresh water back in, and your done.

When do add de-chlorinater to the fresh tap water? Are the fish being exposed to some chlorine when you refill straight from the tap?

here is a gadget someone in here created. I can't take the credit for this but I wanted to pass it on. If anyone knows who created this please let me know.....

its great because you can actually leave and never have to worry about water level going past the T. then after you're done taking the water out, hook it up to the sink and fill it back up. NO BUCKETS!!

You substrate will also be very important with a low tech tank, you want a good nutrient rich substrate so plants get food without you adding any fertilizers to the water column.

Here's some low tech reading http://www.barrreport.com/showthread...on-CO2-methods

Wouldn't that mean putting non dechlorinated water into your tank and really fudge up your bacteria

Tbarabash: possibly. but I have had no issues at all. I also put a dechlorinator in the tank like a cap full per every 10-15 gallons of water. I also never clean my gravel, bio balls or remove the gunk in my sump, im sure that helps a lot.

What things do plants not absorb?
