Like charlie said check the watts on the pumps. The grunfos may especially turn out to be an expensive pump rather than free.

That grunfos is a big pump, check the wattage on it cause Id say it would be right up there too. It may be an overkill for what your planning.


The Grundfos is 350W, how expensive would it be running full time?

Hi Ripturd.
Your going through the same thing I have with latex instead of PVA.
Sucks hey :(

I've found the best thing (and I've tried a lot of things) is high powered pressure washer with hot water running into it.
Only a glass scraper gets the thin stuff off - and it takes a lot of work.



Yeah sucks for sure, might try a glass scraper or similar. Work has a hot water pressure cleaner, I might have to see if I can use it.

Well, that's too much...at least I have a good pump for transferring or draining tanks. Not sure if the Fluval with have enough gusto for the job so might have to find another one. I think I will run the Fluval and see how it goes...it's only 50W so will be a lot cheaper to run.

I use an Aquapro AP3000DW that draws 35W and it turns over my 1000L FT every hour plus supplies water to about 1.5m head height where there are 3 vertical flooded pipes each 4m long… I have 3 IBC GBs and my system is constant flood CHIFT PIST. If it wasn't for the flooded pipes needing water I think I could get enough flow with a 20W pump or so.

Got a barracuda 10kL which is overkill for the system we have. But it was $100 brand new from the irrigation shop as they ordered for someone who didn't end up wanting it. It draws 150w but on our flood drain it ends up at like $3 a week. So that's not breaking the bank.

If you had the big pump running flood drain at 15 in the hour then that cuts it back to roughly $5 a week

I think you'll find it will overwhelm the SLO and flood the FT.

The plan was to split the flow from ST, a line to the FT with Venturi and another circulating back to the ST allowing for further aeration.

Good point, I find myself with tunnel vision when thinking of my set up. It has taken so long to decide how I want it I fear changing things will prolong my agony of indecision.

Good to know, my smaller pump should do all I need it to for now then.

Cheers to you all for the feed back.
