so basically normal activated carbon will do when I do my weekly water changesthe water is fine for about 3 days then starts to go yellow again
May be better to just invest into a diatom filter. It will clear the water quickly.
Dig the toilet bowl idea!
Yes it will I have used it for this reason.Diatom filters will clear up particulate matter quickly. They will not remove the yellowing from the water caused by tannins released by the wood. This is the same for any mechanical media commonly used in aquariums. You need to use one of the chemical media for this.
Yes it will I have used it for this reason.
But let me provide proof to better educate you on the matter. Copied from there manual:
"We are sure you will find the Diatom D-1 Filter to be very valuable and versatile tool once you
have mastered its operating principles. For instance: a small bag of water softening material placed inside
the jar will aid you in controlling water hardness; or to correct yellow water we suggest you use our
SUPER-CHAR, a highly activated carbon for use in your Diatom D-1 Filter."

Yes, I have read Diatom's web site and have used them for about 40 years. Let's just say that on this topic the manual is a bit of hype on the part of the manufacturer.
Having tries such methods, I have found them marginal, mostly because it doesn't take too much to clog one, due to the fine filtration. Because you use a Diatom filter as an occasional filter, not all the time, it is limited in the amount of good any chemical media will have.
Your much better off placing such media in your sump or other filtration.
