Hi all,

Wonder if you can help.

My tank at the moment is using KH like you wouldn’t believe. Levels I have never seen before.

I am currently dosing Red Sea Foundation B (image below), alongside foundation A and C.

My question, Is there a cheaper alternative available in the UK with the same quality? Or would anyone know a reason as to why the KH is depleting so quickly?

For reference, I like to keep the KH around 10 and dosing around 212ml per week to maintain this level! (via automatic daily dosing of 30ml)

Hi guys, does anyone know what these shiny green bubbles are? They are fairly hard.

Guys my Chaeto is developing clear strands, like the green has been stripped from it. Too much light? Not enough nutrients? Am getting mixed results online. Can anyone help?

Guys does anyone know why suddenly I have 0.5mg/l of Nitrite in the water column?? Almost like the nitrifying bacteria has stalled somewhere along the line.

I’ve never had nitrite until recently (with the exception of cycling). I’m at a loss….the only recent changes have been three new frags (leather and gorgania)

Is anyone able to ID these for me please?

Morning from London! Just found these guys in my sump’s reactor. Any idea what these are and if I need to be concerned?
