Be sure it has (or you get later) a DI resin attachment. The RO membrane alone will not eliminate PO4 or silicates.leesanhua said:eerrr... i use tap water to top up and water change.
will get a RO soon.
Always a must when using tap water to add some sort of conditioner. Personally I prefer Prime but Amquel works just fine.but i do put AMQUEL PLUS to reduce the ammonia, nirite and nirate.
The lawnmower blenny and the scooter will not compete for food sources but adding a fish is not your solution. Lawnmowers will typically only eat green film algaes. Many do not accept prepared foods nor macro algaes and cyano is definately not on the menu.the red thing keep coming back. i don't dare to buy a lawnmower blenny because i affraid that it will consume all the antural food as i have scooter blenny which only consume natural food. so...? should i buy the lawnmower?
