Hi all,not posted for a while...but summer pastimes have meant the tanks have been on the back burner for a while.
I recently tested my hightech tank for nitrates and the results showed bright red on the test strips,as oppossed to pale orange on my low tech.

Am currently feeding tnc complete and seachem suppliment.

Just checked my water parameters on the severn trent website.

Do i really need to add more N?
