Have been doing all the regular water changes e.t.c, however my nitrate is extremley high about 80ppm. I've increased water changes to 25% each week and have been trying to get a few extra ones in between. I use RO
water and my tank is low stocked.
I spoke to the LFS
whom all have marine set-ups at home. The bloke said the only way to sort the problem out is to remove all the rock, use a gravel cleaner and stir the substrate so the filter can drag all the 'crap' out.
I walked out of the shop in a daze! My tank is several metres long and so deep I can only reach the bottem of the tank if I'm using a step ladder! Alright I'm not that tall, but is this really the only way? will I have to do this every year?! 8O
