Hey everyone here are some pictures of what im dealing with. The tank is a 29 gallon (19in tall). All purpose sand(Lowes) for substrate, lights are on for 4 hours in morning 4 hours in evening. I have a stingray and a new current led from todays auction. I am dosing twice a week with ez green and liquid carbon every other day... no co2. I have Fert-tabs in the substrate for the crypts Nitrates stay around 10-20ppm kh and gh around 100... Let me know whatcha think the best way to tackle it.
