Hi I have an old time metal 20 gal
stand. I have of course a 20 gal
tank on top. I also have a 10 gal
on the bottom. It is the bottom tank I have a problem to clean. I do water changes 7-10 days. But it is cleaning the substrate that has me concerned. I bought a small siphon bottom cleaner. But the siphon doesn't doesn't start be cause of the angle of the hose and the bucket. I tried cleaning with just the hose. But a siphon never starts. there is mulm on the bottom that would be nice to clean up. Any ideas?
