hiya my tank is now around 3 mths old since setting up from new using uncured rock now i have brown leafy plants growing ,what lloks like blades of grass and the last one can only be said to look like fern which is stacnding around 1 inch high are all the abovew sage por not or shall i add rowa phos and destroy all alagae as i have some patches of slime alages and hair algae is this normal during first years
Its very normal to get all these things within the first 6 months with uncured rock. Just keep doing your water changes to keep the nitrate down, use rowaphos to help reduce the bad algae (brown/green)and use supplements like seachem calcium or carib-sea "purpleup" to encourage the nice purple calcerous algae to grow instead.
Dont worry about any of the leafy algae's they are all good, they use up nitrate so are no harm at all.
