Hi,
I am currently contemplating buying a economicable usable PH controller for planted tank as well as in a range usage for the Marine Ca Reactor system
I know Bioplast cost a 100 odd dollars...
May I have reviews, price and where to purchase cheaply : Bioplast , ehiem , Dennerele, Sera, ..??
Also...I heard saw Denitrinators in a Dynamax Catalogue...donno it it is good or not>
I know there is Tetra Nitrate Minus which is also biological filtration.
Are there any De-Phospaters..? without chemical filtration as well?
Thanks for the help!
Jo
