HBH Balance Blocks

[Dsdaley77]

Anyone have any experience with these? They claim to work much like a two part system regarding PH, Ca and Alk. Did a search and nothing came up.

I've never seen the one you are asking about - but a company called Sea Labs sells a line of these slowly dissolving blocks for a variety of purposes.
I have put one or two into my system to see what they would do -

They slowly disappeared, but I didn't notice any difference. It wasn't really a fair test as I dose ALK/CALIUM anyway and I didn't use the number of required blocks for my water volume. (Doing so would be too expensive for a system my size)

I'm a bit skeptical - I guess they could prevent complete exhaustion of ALK - but I don't see how they could maintain a balanced system either.

If you want - you'll find more info by googling the sea lab products. Some people like them - others question their effectiveness. I couldn't afford them either way for my system.
