Hi, I have a 100 gal system, and I did a water change on it a few days ago; how long should I wait before changing another 15 gallons? I am trying to reduce excess nutrients and have not yet bought a phosphate reactor, ...

clues/hints/advice please, ...

I bet you could do 15 gallons at least every other day w/o harming anything

so long as it is the right salinity and has been properly aerated, you can change quite a bit often.

as long as the salinity, ph and temp are the same you can change as much as you want.

^ what Andy said. I like doing larger because it's easier. You could change 15gallons everyday and it would be fine as long as you're matching those three levels.

use rapid denitrafication method. (look it up). this method required multiple small water changes performed right after the other. this means you do 10 gallons let the tank run for 20minutes and do it again. no worries as it reduces nitrates greatly.!!! i do 10 at a time repeated three times.

I had a small outbreak of a brown algae on my sandbed. I did the following and it has helped a lot. Started rinsing my frozen food before feeding, cut my light cycle back a couple of hours, feed 1 x per day instead of 2, water changes (10%) every 3 days for a week, placed a small power head on one end of the tank blowing across the substrate.
