Just noticed that the bubble count was down to 5bpm without me altering the control valve, it was set at 30bpm is this normal having to keep increasing the Co2 after 3 days? or might i have a leak?

I'm taking the unit back to M/A this morning to see if they can see what the problem is,I was hoping to find the answer on this forum but nobody has replied to my post sniff sniff.

Hope it works out.

I just found out there is a MA near me (well close enough) and I was going to ask them if they do refills of CO2 in case I bought the JBL 602.

Update

Been dosing for a month now the only difference so far is the reduction in BBA, just planted Crptocoryne walkeri and Hemianthus callitrichoides in the centre front of my tank.
Will do another update next month.

Think its been about 12 weeks since I first started using the Co2 and ferts, after some initial teething problems I can now say my plants are all growing well at a fast pace.
Hygrophila polysperma grows so fast I would recommend this plant to anyone.
