There are several options for dosing. I use seachem phosphorous. There are several DIY solutions. Feeding more can also work. Go over to the chemistry forum for many, many discussions about low phosphates. if your nitrates are 5+ I would think you also have phosphates, but just a guess.I can start testing for phosphates. Can phosphates be added to the water? Is there a non-dosing remedy for low-no phosphates?
If you get a test kit i really recommend one of the hanna checkers over the kits. Its much easier for phosphates. I have the ULR phosphorous but there are a couple of different ones now.
