Phosphate removal is a way to limit algae by blocking the supply of a key growth ingredient. Don’t fertilize your plants while doing this. ;)

Older tanks, with 25% or less weekly water changes, can accumulate an amazing level of nitrates. Sometimes the fish get used to it. But they are so high that new additions wilt and die.
And sometimes we unfairly condemn the shop for selling poor fish. That is one of the reasons why many return policies ask for a water sample. I have been carrying on about how many of us, myself included, need to increase the number of water changes. Under the title of “An Instant Nitrate Reduction Method” the author Stan Hunter, with a Salt-Water site, has very succinctly showed how this works. They included an excellent graphic for those of us who are or are also visual learners.

I hope these are of use. I for my part, have GOT to got make a heck of a lot of water changes this afternoon rather than spend further time summarizing another person’s thoughts. ;)
All the best,
30 liters down, 1 on the floor. (The towels are already in the wash.) At least 379 liters to go.
