so since nobody replied, i just went ahead and do it. but, i added a little java moss island at the front. on the right side - just crypts. on the left - i think it is a high tech plant but i already purchased it before knowing it is high tech.. so... lol..
the old soil was mixed with gravel and look awful. so i throw them out and replace with a new batch
of ADA New Amazonia soil. filter is simple hob and has been running for 1 yr+ so the cycling will be faster IMO.
the day after:
will be sifting up those soil on the sand soon.
