Hi all!! Well as the subject states I have a issue with SHA. I changed my tank over to a lower light tank without c02 a while back.Everything was running great with NO algae atall. Before change: ( Running for about 3 months ) 110 liter tank +- Little dosing 112 watts at 10 hours a day. DIY CO2 Had no algae atall but my time became limited.Tank was very stable and looking awsome. Due to time issues i changed the tank to a low maintanince tank. 110 liter tank +- No dosing 56 watts at 6 hours a day. removed C02 The tank was runnig great for about 1 and half months.Plants was still doing good and no algae.Removed some of the swords during this period. Now about a week and a half ago Staghorn algae started to bloom...no other algae is present. I have been doing daily 30% waterchanges sinice it started but nothing is working.I have removed as much of teh algae manually aswell as the leaves affected buy it. Also i have started to give a little c02 again.Also light period reduced to 4 hours. Sofar the algae have slowed down a little bit but still growing. I do not test my water so do not have figures but with the waterchanges it should be low.And after all i have loads of plants in there.Mostly slow growers. Any ideas guys?
